Within the bigger study of the terrestrial isopods of the iberian peninsula, a new species is described for the region of Murcia, Armadillidium bifidus n. sp., this species is ascribed to serratum group, and called after the characteristic scale-setae that ornate its cuticle. Furthermore, its diagnostic characteristics are discussed , as well as its affinities with the rest of the group.
... The evolutionary and systematic significance of these characters remains unknown and, accordingly, the monophyletic nature and definition of many supraspecific taxa in Armadillidiidae have been questioned (e.g. Vandel, 1962;Schmalfuss & Sfenthourakis, 1995;Schmalfuss, 2005Schmalfuss, , 2008Schmalfuss, , 2013. ...
... by using the trace character over trees option, and likelihood-based ancestral character state reconstruction by using the package phytools in R (Revell, 2012). We used the tree obtained with *BEAST as input and reconstructed three discrete characters: (1) myrmecophily, coding species as myrmecophilous or non-myrmecophilous; (2) schisma in pereonite 1 epimera, coded as present or absent in the included taxa; and (3) head morphological types, coded in three states (Vandel, 1944(Vandel, , 1962: (1) Eluma type (only linea frontalis present); (2) duplocarinate type (both linea frontalis, complete or partial, and postscutellar line present); and (3) Armadillidium type (only postscutellar line present). ...
... Although as a family, the group seems clearly defined and monophyletic (Schmidt, 2003(Schmidt, , 2008Schmalfuss, 2013), many of the currently accepted genera within Armadillidiidae (most of them originally described as subgenera) are not based on clearly derived character states; hence, their monophyletic status has often been doubted (e.g. Vandel, 1962;Schmalfuss, 1989Schmalfuss, , 2008Schmalfuss, , 2013. No phylogenetic studies including a significative number of representatives of Armadillidiidae have been performed, and the evolution of characters traditionally used in systematics and taxonomy of the family is far from being well understood. ...

The terrestrial isopod family Armadillidiidae presents higher diversity in karstic areas, with fewer species present in areas with reduced suitable subterranean habitats, such as siliceous sandy soils. Myrmecophily, although not widespread in the family Armadillidiidae, can help these animals to colonize sandy substrates, as is observed in several populations of myrmecophilous Armadillidiidae species in central and southern Spain. Morphological examination and multilocus phylogenetic analyses, including mitochondrial DNA (Cox1) and nuclear DNA (18S, 28S and H3) markers, indicate that these myrmecophilous populations represent four new taxa: Iberiarmadillidium pinicola gen. & sp. nov., Iberiarmadillidium psammophilum sp. nov., Iberiarmadillidium sakura sp. nov. and Cristarmadillidium myrmecophilum sp. nov. Some of the main diagnostic characters used in the taxonomy of Armadillidiidae are not clearly apomorphic. Among head morphologies, Eluma type seems to be the ancestral state, being typical of several unrelated lineages; duplocarinate and Armadillidium types are derived states observed in unrelated lineages. The presence of a schisma is a convergent character state, because it has been identified in several taxa nested in unrelated clades. The newly described taxa present patterns of morphological stasis and homoplasy, likely to be associated with their shared myrmecophilous habits. The generic taxonomy of the family needs a deep revision including phylogenetic approaches and thorough taxon sampling.

The examination of the collection of terrestrial isopods of the Museo Nacional de Ciencias Naturales de Madrid has allowed us to recognize a new genus and a new species, Estenarmadillidium granulatum n. gen. and sp. from Castilla La Mancha (Spain), belonging to the family Armadillidiidae Brandt, 1833, and it's located in the Elumiinae subfamily Vandel, 1962 because of its cephalic structure.The diagnostic features and the affinities of the new genus and species are discussed. In the Ibero-Balearic area, Estenarmadillidium granulatum n. gen. and sp. can be mistaken with Cristarmadillidium muricatum (Budde-Lund, 1885) in a basic examination due to their hypertrophic granulations. However, the lack of schisma in C. muricatum, among other characteristics, can be used to discern between the two species.

... All species are strictly coastal and have halophilic habits (Taiti & Ferrara, 1989;Schmalfuss, 2003). Armadilloniscus species live closely to the sea, on sandy or rocky beaches using both stones and plant remains as a refuge (Vandel, 1962;Taiti & Ferrara, 1989). Their flattened body shape and clinger ability (Schmalfuss, 1984) are a strategy to adapt to the unstable environment in which they live. ...
... Their flattened body shape and clinger ability (Schmalfuss, 1984) are a strategy to adapt to the unstable environment in which they live. It allows them to cling tightly to the substrate, either on the lower surface of stones, wood or other remains deposited by the waves (Vandel, 1962). In this way they can resist the battering of the waves, submersion and periods of marine transport on floating objects to which they adhere. ...

Armadilloniscus Uljanin, 1875 is a genus of halophilic woodlice that strictly occurs in coastal habitats. Two species are known in the coastal areas of the western Mediterranean and only one species, A. ellipticus, was previously recorded in the Iberian Peninsula and the Balearic Islands. Another species, A. candidus, is reported for the first time in Asturias and the Iberian Peninsula. This species could have arrived to the Atlantic coast attached to floating objects, like logs, trunks or plants. The record shows the capability of A. candidus to adapt to coastal areas of the Atlantic. Until now, this species was only documented in the Atlantic by two single records from the French coast and the Azores islands. Ecological data are provided of this species in the Iberian Peninsula. Finally, figures of the habitus and of the morphological characteristics are provided, that allow the identification of the two species of Armadilloniscus present in the Iberian coastal areas.

Los isópodos terrestres de Andalucía han sido objeto de numerosos estudios, por lo que el inventario de especies citadas ascendía a 90. En este trabajo se han estudiado 2.046 ejemplares pertenecientes a 41 especies y se ha realizado una revisión bibliográfica de todas las citas anteriores. Como consecuencia, 13 especies se eliminan del inventario original por tratarse de errores en la determinación, porque su estatus como especie es dudoso, o por la carencia en su descripción de rasgos que permitan distinguirlas de otras especies de manera inequívoca. Por tanto, la fauna conocida de isópodos terrestres de Andalucía está formada por 77 especies, pertenecientes a 30 géneros y 11 familias. Para todas ellas se facilita su distribución en Andalucía y una distribución general en el área iberobalear. Se proporcionan datos inéditos para 41 de ellas. Se citan 4 nuevas especies por primera vez para Andalucía, y otras 20 especies para alguna de las provincias andaluzas. La familia Porcellionidae Brandt & Ratzeburg, 1831, con 38 especies, y el género Porcellio Latreille, 1804, con 24 especies, son los que presentan mayor riqueza en la región. A nivel provincial, Málaga con 39 especies conocidas es la más rica, seguida de Cádiz (36) y Almería (34). En Andalucía solamente se conocen 11 especies endémicas de isópodos, el 14% de su fauna, frente al 52% del área iberobalear. De todas las especies citadas, solamente cuatro (5%) son cavernícolas.

A new species of the family Armadillidiidae Brandt, 1833 is described, pertaining to the genus Cristarmadillidium Arcangeli, 1935, C. alticola n. sp. The specimens were captured in a pitfall trap located in a mesovoid shallow substratum (MSS) at Peñones de San Francisco (Sierra Nevada, Granada at 2.505 m.a.s.l.), which is located at an altitude that not many isopods are able to reach in Europe. Among other things, it can be recognised by its colour, its smooth pereonites, the three first pairs of pereopods of the male with brushes of the long sharply setae and its mountainous location. On the contrary, the other three species of this genus have grainy pereonites, they are lacking brushes of setae and are troglophilic species in low altitude areas. This morphological characteristics and its habitat make C. alticola n. sp. the possible oldest species in the genus, which could be a remnant of a terciarian fauna that evolved in the mediterranean area.
... In the Iberian and Macaronesian species of the Atlantic group, there is a single glandular field on each tergite, generally semi-ovoid and proximal to the lateral margin, or extending along the entire edge. In some species (such as Porcellio xavieri Arcangeli, 1958 or Porcellio incanus Budde-Lund, 1885) the glandular field may be totally absent or very small (Vandel, 1951(Vandel, , 1960b(Vandel, , 1962Schmölzer, 1965). ...

Porcellio wadianae sp. nov. (Crustacea: Oniscidea: Porcellionidae) is described from the Extremadura region, Spain, Iberian Peninsula. The new species can be classified within the so-called "Porcellio Atlantic group", def-fined by Vandel. It is characterized by having an integumentary glandular system uncommon within this genus and by other characteristics that differentiate it from the other species of the same group present in the Ibero-Macaronesian and Northern African region. In addition, we report additional observations on woodlice species collected in Extremadura, one of Spain's most poorly known regions concerning terrestrial Isopod fauna.
... Only two Philoscia species occur in areas of the westernmost part of Europe, Philoscia muscorum (Scopoli, 1763) and Philoscia affinis Verhoeff, 1908. Philoscia affinis usually shows arboricolous habits (Vandel, 1962) and mainly lives in damp forests near watercourses or on waterlogged soils (Vandel, 1962;Boeraeve et al., 2017;Segers et al., 2017;Hughes, 2019;Gregory, 2020). It has been reported from European continental sites in Austria, Belgium, Croatia, France, Germany, Great Britain, Hungary, Ireland, Italy, Slovenia and Spain (Schmalfuss, 2003;Vilisics & Lapanje, 2005;Lefebvre, 2012;Farkas & Vilisics, 2013;Boeraeve et al., 2017;Segers et al., 2018;Hughes, 2019;Gregory, 2020). ...

... On the contrary, P. muscorum is an ubiquitous species that inhabits mountainous environments, deciduous forests on humic soils, damp grasslands, salt marshes and estuarine meadows (Vandel, 1962), especially in damp microhabitats as dead wood, leaf litter or moss, since the species shows negative phototaxis and cannot resist desiccation (Cloudsley-Thompson, 1956;Vandel, 1962). It has been reported from Belgium, Czechoslovakia, Denmark, France, Germany, Great Britain, Greece, Hungary, Ireland, Italy, Netherlands, Norway, Poland, Portugal and Spain (Schmalfuss, 2003), and was introduced into North America (Jass & Klausmeyer, 2000). ...

Bulletin of the British Myriapod & Isopod Group: 33, 79-87. "The presence of Philoscia muscorum (Scopoli, 1763) in the Iberian Peninsula has been questioned by some authors in the past. New data from northern localities in Spain confirmed the species in the Iberian Peninsula. Additionally, new ecological data and sympatry with Philoscia affinis Verhoeff, 1908 are reported. Finally, figures on the morphology of P. muscorum and P. affinis are provided.
... Porcellio scaber was first described in Western Europe and belongs to the scaber-obsoletus-group. In general, the materials of P. scaber collected in South Korea agree well with the original description by Latreille (1804) and the re-description by Vandel (1962). Porcellio scaber contains the following six subspecies: Porcellio scaber americanus Arcangeli, 1932; Porcellio scaber flavobrunneus Collinge, 1917;Porcellio scaber flavomaculata Collinge, 1918; Porcellio scaber japonicus Verhoeff, 1928;Porcellio scaber lusitanus Verhoeff, 1907;and Porcellio scaber scaber Latreille, 1804. ...
... In fact, these characteristics were found to be mixed within the same population and included intermediate forms, so they were not used as characteristics to define subspecies of Porcellio species (Caruso et al., 2007;Karasawa and Nakata, 2018;Cifuentes, 2019). Vandel (1962) also mentioned the above in re-describing P. s. scaber and P. s. lusitanus, and concluded that subspecies would be valid only if genetic differences clearly isolate them. The differences in the characteristics mentioned above were also found among Korean materials, but they included intermediate forms and did not consistent with genetic differences (Table 1, Fig. 3). ...
... In terms of body color, P. scaber is mostly dark gray, but there are many variations, such as pale yellow with irregular pigmentation, gray with reddish pigmentation, and occasionally no pigmentation (Vandel, 1962). Color variation was also observed in the Korean materials, and there were no significant differences in morphology other than body color. ...

The common rough woodlouse Porcellio scaber Latreille, 1804 is newly reported from South Korea with following diagnostic characteristics: the presence of distinct tubercles on body; the strongly developed lateral lobes of head; the presence of notch on tracheal field of pleopod 1 exopod; and distinctly short exopod of uropod. This species is reported to be cosmopolitan, but there were no taxonomic records of it in South Korea. All voucher specimens were collected from humid shaded areas adjacent to the eastern coast of South Korea. Organismal ecology and scanning electron microscope photographs are provided. In addition, the results of CO1 analysis of individuals representing the different color and morphological variations are provided.

A list of eighteen terrestrial isopods (species or subspecies) is presented. Six of them (Chaetophiloscia elongata, Chaetophiloscia cellaria, Platyarthrus costulatus, Platyarthrus schoblii codinai, Acaeroplastes melanurus and Porcellionides sexfasciatus lusitanus) are new to the fauna of Andalusia and three others (Porcellionides pruinosus, Porcellionides fuscomarmoratus and Armadillidium mateui) are new to the fauna of Murcia. Another nine species (or subspecies) are recorded for the first ime in some provinces of Andalusia.
... In the specimens studied, the same type of scale-setae is found regardless of body size, which is not the case with other characters dependant on allometric growth. With the results obtained, we can affirm that both the "petiti" form as indicated by VANDEL (1962), and Porcellio dilatatus bonadonai Vandel, 1951 fall within the range of normal variability of the nominal species, so they have no differential taxonomic entity. ...

The objective of this work is to make a review of the main morphological characters used in the identification of this species, in order to determine the degree of its variability and whether these characters can be used to separate subspecific entities. 759 specimens from 28 sampling points of Porcellio dilatatus Brandt, 1833, were studied: 644 of them were captured in the Sierra Norte’s caves of Seville, and the rest were found in thirteen different Spanish provinces. This study allow us to indicate that while the first exopod of the male’s pleopod has an inner tip well marked in most of the specimens, that is developed throughout its growth; the exopod of male’s second pleopod, and the female’s first and second pleopod vary very little in form during their growth. Although the first exopod of the male’s pleopod may or may not have a notch, this notch is always present in the exopodites of the male’s and female’s second pleopod, and it is also very evident in the immature individuals. In males, the development of secondary sexual characteristics begins with the pleopods, continues with the first pereiopods, and finally affects the seventh pereiopod. Both the telson and the uropods present some variations in comparison with the normal type, even in specimens of the same colony, so they should not be used for the discrimination of subspecies not even forms. In the specimens studied, the same type of scale-setae is found regardless of body size, which is not the case with other characters dependant on allometric growth. With the results obtained, we can affirm that both the “petiti” form as indicated by VANDEL (1962), and Porcellio dilatatus bonadonai Vandel, 1951 fall within the range of normal variability of the nominal species, so they have no differential taxonomic entity.

RESUMEN: En este artículo se presentan los isópodos terrestres recolectados durante los muestreos efectuados en diversas campañas realizadas en las cuevas del Parque Natural de la Sierra Norte de Sevilla, durante los años 2002-2004. Se han identificado 673 ejemplares pertene-cientes a cinco especies de isópodos terrestres: Haplophthalmus danicus, Lucasius pallidus, Porcellio incanus, Porcellio dilatatus y Eluma caelatum. Solamente P. dilatatus puede ser considerado como troglofilo, mientras que P. incanus presenta un carácter troglófilo menos marcado, ya que aunque es habitual en las cuevas principalmente de la zona sur peninsular, en el resto de su área de distribución se comporta como epigea. Las otras tres especies son trogloxenas. Se cita por primera vez para la provincia de Sevilla y Andalucía a H. danicus y por primera vez para la provincia de Sevilla a L. pallidus. El inventario de los isópodos terrestres de la provincia de Sevilla comprende 17 especies. ABSTRACT: A check-list of the terrestrial isopods found in the caves of the Natural Park of the Sierra Norte de Sevilla, during the years 2002-2004 is presented. A total of 673 specimens belonging to five species of terrestrial isopods have been identified: Haplophthalmus danicus, Lucasius pallidus, Porcellio incanus, Porcellio dilatatus and Eluma caelatum. Only P. dilatatus can be considered as a troglophile. P. incanus presents a less marked troglophile character, because although usually inhabits caves in the South of the Iberian Peninsula, in other distribution areas behaves like epigean. The other three species are trogloxene. H. danicus is cited for the first time from the province of Seville and Andalusia, and L. pallidus from the province of Seville. The check-list of terrestrial isopods in the province of Seville includes 17 species.
... Presently, Stenoniscus comprises four species (Schmalfuss 2003): S. pleonalis Aubert & Dollfus, 1890 from the northern coasts of the Mediterranean east to the Aegean, Bermuda, Bulgaria, Madeira and Mexico; S. carinatus Silvestri, 1897 from coastal areas of Croatia, Italy, Portugal and Spain; S. aenariensis (Verhoeff, 1942) and S. plutonis (Verhoeff, 1942) from Ischia Island, Italy, both most probably junior synonyms of S. pleonalis according to the short descriptions by Verhoeff (1942). The genus can be defined by animals of reduced size (up to 3.5 mm), body slender with lateral sides parallel, dorsum bearing longitudinal ribs and tubercles, sometimes reduced, epimera of pereonites 2-7 with lateral margins grooved, pereonites 4-5 ventrally with lateral sternal thickenings and 6-7 with sternal plates, antennula of two articles, pleonite 1 absent, uropods of conical shape, pleopod exopods without respiratory organs, and pleopod 1 absent on females (see Vandel 1962;Schmidt 2003). ...
... In the Caribbean region, four species of Armadilloniscus have been recorded: A. caraibicus from Venezuela, A. ellipticus (Harger, 1878) from the Atlantic coasts of USA and Bermuda, A. ninae Schultz, 1984 from Belize, and A. steptus Schotte & Heard, 1991 from Turks and Caicos Islands (British West Indies) (Schultz 1984;Paoletti & Stinner 1989;Taiti & Ferrara 1989;Schotte & Heard 1991).

In this study, we report the results of a taxonomic survey of terrestrial isopods from Isla Grande, a ca 2 km2 island located in the north of Cartagena de Indias, Colombia. We found a total of 17 species belonging to nine families and 10 genera. Eight of these species have been reported only from the Caribbean region, nine are recorded for the first time in Colombia, and three are new to science and described here: Tylos negroi López-Orozco, Carpio-Díaz & Campos-Filho sp. nov., Stenoniscus nestori López-Orozco, Taiti & Campos-Filho sp. nov. and Armadilloniscus luisi Carpio-Díaz, Taiti & Campos-Filho sp. nov. Our revision also determined that the genus Microphiloscia is a junior synonym of Halophiloscia; and moreover, Halophiloscia trichoniscoides comb. nov. is redescribed. We also provide illustrations for Armadilloniscus caraibicus and Armadilloniscus ninae. Most (16) of the species were found in coastal habitats (i.e., beaches, coastal lagoons and mangroves), whereas the tropical dry forest harbored only two species. Molecular phylogenetic inferences supported the presence of three species of Tylos in Isla Grande (i.e., one new species and a new lineage within each of two known species). Our work on Tylos highlights the importance of combining taxonomic and molecular analyses to support taxonomic decisions and uncover cryptic diversity. Due to the multiple threats to Caribbean coastal habitats, taxonomic and molecular genetic research are urgently needed to understand biodiversity patterns of oniscideans in the Caribbean, which will inform strategies for their protection. Such studies will also contribute to our knowledge of their evolution, ecology, and potential uses, as well as the factors that have shaped the remarkable Caribbean biodiversity.

Les Oniscidea présentent une diversité remarquable de systèmes chromosomiques de déterminisme du sexe (hétérogamétie mâle XX/XY ou hétérogamétie femelle ZW/ZZ), dont l'origine reste encore largement inconnue à ce jour. Il a été proposé que ces différents systèmes puissent être le produit de la coévolution entre les isopodes terrestres et Wolbachia, une bactérie endosymbiotique féminisante transmise verticalement par voie ovocytaire. Dans le but de caractériser l'impact de l'endosymbiose à Wolbachia sur l'évolution des mécanismes de déterminisme du sexe, nous avons utilisé une combinaison d'approches génomique, transcriptomique et d'expression de gènes. Tout d'abord, le génome de l'espèce Armadillidium nasatum (caractérisée par un système XX/XY) a été généré et ensuite annoté structurellement et fonctionnellement. A partir de ce génome, des approches de génomique comparatives ont permis la caractérisation de séquences liées au chromosomes Y, afin de mieux comprendre les processus impliqués dans la dégénérescence des gonosomes. Afin d'identifier des effecteurs liés au déterminisme ou à la différenciation du sexe, une approche par gènes candidats a permis de caractériser des gènes à domaines DM, connus pour être impliqués dans le déterminisme du sexe de nombreuses espèces, et d'en mesurer l'expression au cours du temps. Enfin, une phylogénie des Oniscidea a été réalisée en parallèle d'expériences de réversion de sexe afin d'estimer le nombre et la direction des transitions de systèmes d'hétérogamétie au cours de l'évolution des isopodes terrestres. Ces travaux contribuent à illustrer l'impact de l'endosymbiose sur l'évolution des mécanismes de déterminisme du sexe de l'hôte.
... Typically, A. officinalis can live on different substrates, namely sand, silty-clay substrates, or rocks. These pill bugs have mainly nocturnal habits (Vandel, 1962). In the daytime, they remain under stones or other shelters, forming quite large aggregates. ...
... It is thought that aggregation is likely useful for preventing both desiccation and predation, as reported for many terrestrial isopods (Broly, Deneubourg, & Devigne, 2013;Broly, Devigne, Deneubourg, & Devigne, 2014;Broly, Mullier, Deneubourg, & Devigne, 2012). A. officinalis is an iteroparous speciesthat is, producing offspring more times in a lifetime-and the reproductive period depends on the particular region to which it belongs-for instance, from June to August in France (Vandel, 1962), mainly in October in Israel (Warburg, 2013), and from May to July in Sicily (Messina et al., 2011;Messina et al., 2012). ...

Effective communication is essential in animal life to allow fundamental behavioral processes and survival. Communicating by surface-borne vibrations is likely the most ancient mode of getting and exchanging information in both invertebrates and vertebrates. In this review, we concentrate on the use of vibrational communication in arthropods as a form of intraspecific and interspecific signaling, with a focus on the newest discoveries from our research group in terrestrial isopods (Crustacea: Isopoda: Oniscidea), a taxon never investigated before in this context. After getting little attention in the past, biotremology is now an emerging field of study in animal communication, and it is receiving increased interest from the scientific community dealing with these behavioral processes. In what follows, we illustrate the general principles and mechanisms on which biotremology is based, using definitions, examples, and insights from the literature in arthropods. Vibrational communication in arthropods has mainly been studied in insects and arachnids. For these taxa, much evidence of its use as a source of information from the surrounding environment exists, as well as its involvement in many behavioral roles, such as courtship and mating, conspecific recognition, competition, foraging, parental care, and danger perception. Recently, and for the first time, communication through surface-borne waves has been studied in terrestrial isopods, using a common Mediterranean species of the Armadillidae family as a pilot species, Armadillo officinalis Duméril, 1816. Mainly, for this species, we describe typical behavioral processes, such as turn alternation, aggregation, and stridulation, where vibrational communication appears to be involved.

Five new species of terrestrial isopods from Liguria and surrounding regions are described: Buddelundiella zoiai sp. n. (Buddelundiellidae), Sardoniscus marmoratus sp. n. (Oniscidae), Cylisticus poggii sp. n. (Cylisticidae), Porcellio incavatus sp. n. (Porcellionidae), and Alloschizidium segestanum sp. n. (Armadillidiidae). Buddelundiella zoiai, Cylisticus poggii and Alloschizidium segestanum were collected in edaphic environments, while Sardoniscus marmoratus and Porcellio incavatus were found in leaf litter or under not deeply embedded rocks. The diagnostic characters, the affinities and the distribution of the new species are discussed.
... Outre les éventuelles différences de couleurs (les mâles adultes étant régulièrement plus foncés que les femelles), l'identification du sexe d'un cloporte passe ensuite par l'examen des organes génitaux externes. Ceux-ci sont par ailleurs à la base de la plupart des études sur la systématique des Isopodes (Vandel, 1943(Vandel, , 1960(Vandel, , 1962Noël and Séchet, 2007). Ils incluent premièrement, chez le mâle, une apophyse génitale ("pénis"), c'està-dire un organe dérivé de la membrane articulaire reliant péréion et pléon et contenant la portion terminale des canaux déférents (Legrand, 1946). ...

La différenciation sexuelle des Isopodes dépend d'une hormone sexuelle protéique, l'hormone androgène (HA), caractéristique des Malacostracés. Cet Insulin-Like Peptide suffit à induire par sa présence la différenciation mâle de ces Crustacés. Nous avons identifié in silico le transporteur circulant de l'HA, l'IGFBP-rP1, chez de nombreuses espèces d'Isopodes ainsi qu'à l'échelle des Crustacés. De la même façon, nous avons identifié deux récepteurs transmembranaires, l'IR1 et l'IR2, issus d'une duplication de gène spécifique des Malacostracés. Les patrons d'expression de ces gènes ont été étudiés sur notre espèce modèle, Armadillidium vulgare. Av-IGFBP-rP1 et Av-IR1 sont exprimés de manière ubiquiste et tout au long du développement. Av-IR2 est aussi exprimé à chaque stade de la différenciation mais ce transcrit est quasi-spécifique des glandes androgènes et ovaires. Une approche par ARNi a confirmé l'implication de ces trois protéines dans la voie de signalisation de l'HA. En effet, l'inhibition de l'HA, Av-IGFBP-rP1 et Av-IR1 provoquent l'hypertrophie des glandes androgènes, suggérant leur implication dans une boucle de rétro-contrôle de l'HA. L'inhibition de Av-IR2 semble seulement provoquer la différenciation d'ouvertures génitales femelles. Ces phénotypes sont comparables à ceux des intersexués mâles induits par la bactérie féminisante endogène Wolbachia. Nous montrons cependant que la bactérie altère seulement l'expression de l'HA et pas celle des récepteurs. Enfin, nous avons testé l'effet du bisphénol A mais nous n'observons pas d'altération de la différenciation sexuelle des larves lors d'expositions à ce perturbateur endocrinien exogène.

Terrestrial isopods (Oniscidea) are crustaceans that thrive in terrestrial environments. This study provides an overview of the major topics in terrestrial isopod research during the last 70 years in order to provide an example of publication practices in invertebrate zoology and to examine how basic research in this area is transferred to its applications. Co-citation analysis and bibliographic coupling based on citation data from the Web of Science Core Collection was used. Findings show that while research on terrestrial isopods expanded in applicative research prioritised by research policies, basic research continues to flourish. The most productive countries in the field include the major developed economies and several smaller nations. In the smaller countries, as well as in France and Italy, the bulk of woodlouse research is performed at a few institutions with traditions in this field. Some of the most influential works have been published in periodicals or monographs that are not indexed in Web of Science or Scopus and lack impact factors. Conference proceedings represent some of the most influential publications in the field. Our findings indicate that smaller and developing economies make significant contributions in invertebrate zoology if their research organisations can achieve continuity of research on a topic. Another conclusion is that journal metrics may be a misleading descriptor of the impact of studies and researchers in this field. Ultimately, these results identify several examples of how basic research in invertebrate zoology leads to applications with considerable socio-economic impact.

El Medio Subterráneo Superficial (MSS) es un hábitat constituido por una red de grietas, fisuras e intersticios colonizados por la fauna subterránea, tanto por especies adaptadas a la vida hipogea como por aquellas venidas de ambientes periféricos. El estudio de este hábitat en España es aún incipiente. En la provincia de Almería únicamente se han llevado a cabo los muestreos a los que hace referencia este estudio, los cuales ya han arrojado algunos resultados. El objetivo de este trabajo es describir y analizar las comunidades de isópodos detectadas en el MSS en la Sierra de Gádor y la Sierra de María. La recolección de los isópodos se realizó mediante Estaciones de Muestreo Subterráneo (EMS) que consistieron en un cilindro de PVC perforado en el tramo inferior para facilitar el acceso a la entomofauna presente a una profundidad de-0,5 a-0,9 m. Las EMS se recolectaron estacionalmente en 2018 y 2019. Se capturaron 4137 ejemplares pertenecientes a tres familias, siete géneros y nueve especies. Para detectar diferencias entre zonas, se ha realizado un Análisis Clúster Jerárquico y modelos lineales generalizados (GLM). El GLM reveló la existencia de diferencias significativas entre ambas sierras, siendo la abundancia mayor en Sierra de María (p<0.001). Las diferencias entre las distintas orientaciones no fueron estadísticamente significativas. El Análisis Clúster Jerárquico clasificó los canchales en dos grupos claramente diferenciados, en uno los ubicados en Sierra de Gádor y en el otro los de Sierra de María.

The exopod of the first pleopod is almost identical to that of P. scaber, but has the posterior lobe with the internal angle more prominent than the external angle, while in P. scaber and other species of the same group the external angle usually exceeds the internal one (see Vandel, 1962;Gruner, 1966;Cifuentes, 2018).

Two new Iberian species of terrestrial Isopods (Crustacea: Oniscidea) of the family Porcellionidae are described. The specimens come from scientific collections preserved at the Museo Nacional de Ciencias Naturales de Madrid and at the Centro Iberoamericano de la Biodiversidad of the University of Alicante (Spain). These had previously been identified as Porcellio ingenuus Budde-Lund, 1885, and published under that name in various scientific papers. A re-examination of these specimens and their comparison with the holotype of P. ingenuus, located in the Zoological Museum of the Moscow State University (Russia), has allowed them to be described as new species, assigned respectively to the genera Mica Budde-Lund, 1908 and Porcellio Latreille, 1804. Mica iberica sp. nov. comes from Priego (Cuenca) and is the second known species of this genus. Porcellio cibioi sp.nov. was collected in Salamanca and is closely related to Porcellio scaber Latreille, 1804. In this paper we also illustrate and describe the type-specimen of P. ingenuus briefly, a species described in the 19th century based on a single female specimen from Lisbon (Portugal).

Three new species in the genus Niambia are described from southern African caves: N. botswanaensis sp. nov. from Diviner’s Cave (Botswana), N. ghaubensis sp. nov. from Ghaub Cave and N. namibiaensis sp. nov. from Märchen Cave (Namibia). All these species show troglomorphic traits such as absence of body pigmentation and eyes. These are the first troglobitic species recorded in the genus. Most of the other species of Niambia are epigean and occur in semi-arid environments in the Afrotropical Region.

An overview of the Estonian terrestrial isopod fauna is given, based on literature data and material collected from 1984 to 2021. The identified material consisted of 10915 specimens belonging to 14 species and collected from 172 localities throughout Estonia. In combination with previous data from the literature data, there are now reliable records of 16 species of woodlice from Estonia. Two species, viz. Platyarthrus hoffmannseggii Brandt, 1833 and Hyloniscus riparius (C. Koch, 1838), are new for the fauna. The latter has probably colonised Estonia recently and range expansions have been reported elsewhere. The data on Philos-cia muscorum (Scopoli, 1763) are dubious, and this species is currently excluded from the Estonian list.

Three new species of Androdeloscia Leistikow, 1999 from the Brazilian Amazonian rainforest are described. Androdeloscia bicornuata sp. nov., A. paraleilae sp. nov., and A. micropunctata sp. nov. were distinguished from the 26 other species of the genus mainly based on the shape of male pleopod I endopod. Androdeloscia bicornuata sp. nov. differs from all the species in the genus by the complex morphology of the distal portion of the male pleopod I endopod bearing hyaline lamella and two horn-like tips. Androdeloscia paraleilae sp. nov. is characterized by the male pleopod I endopod with simple distal portion, without hyaline lamella, and apex represented by a curved tip and inner margin serrate proximally; and by the concavity on the lateral margin of the first maxilla (except for the A. leilae that is related to other listed characteristics). Androdeloscia micropunctata sp. nov. differs from the remaining species of the genus by the male pleopod I endopod with simple distal portion, without hyaline lamella, and apex truncate bearing a small acute tip in the outer corner; and 5+5 teeth on the first maxilla.

Terrestrial isopods (Crustacea: Oniscidea) are a model group for studying the colonization of land. However, their fossil record is remarkably scarce and restricted to amber inclusions, and therefore amber deposits represent valuable windows to their past diversity and morphology. Here we present a new collection of 11 terrestrial isopod specimens preserved in Albian-aged amber from the Peñacerrada I outcrop, northern Spain, which collectively represent the most thoroughly documented fauna of Mesozoic Oniscidea. The three new genera and species identified belong to three of five major groups of the Oniscidea: Eoligiiscus tarraconensis, new genus and species (Ligiidae), Autrigoniscus resinicola, new genus and species (Synocheta: Trichoniscidae), and Heraclitus helenae, new genus and species (Crinocheta: Detonidae?). These taxa significantly expand the known fossil record of Oniscidea and demonstrate that considerable cladogenesis had already transpired by the Albian. The assemblage represents the earliest-known diversification of Oniscidea, extending direct evidence of terrestrialization in the group back to the late Early Cretaceous. These new taxa exhibit some characteristics that may inform hypotheses relating to general patterns of terrestrial isopod evolution. A discussion is provided about different aspects of the paleoecology and biology of the fossils compared to the Recent fauna. The new species indicate that Cretaceous isopods were a group of considerable adaptive diversity, exhibiting innovations analogous to what Recent isopods would exhibit 105 million years later.

... Porcellionides pruinosus individuals produce two or more generations per year (Achouri, Charfi-Cheikhrouha, & Marques, 2002) and have limited dispersal abilities; therefore, they may respond to environmental changes behaviourally (Morgado, Ferreira, Cardoso, Soares, & Loureiro, 2015) or morphologically (Csonka et al., 2018). Phenotypic reproductive variations have been reported among some population of this species (Achouri & Charfi-Cheikhrouha, 2005) and considered to be forms of resistance to the environmental conditions (Vandel, 1962). In the same context, several examples of environmental influence on the phenotype of P. pruinosus and other isopods were reported (Dangerfield & Telford, 1990;Eroukhmanoff & Svensson, 2009;Winkler & Wallin, 1987); however, none of these studies used geometric morphometrics. ...

Background Isopods shape features are sensitive and respond to several selective pressures which may result in variations of these features. These pressures might reflect the heterogeneity of the environment where an animal lives. Land isopods Porcellionides pruinosus were collected from an agricultural field. Landmarks geometric morphometrics was applied to evaluate its shape changes during two different seasons. The present work aims to (i) assess and characterize morphological changes in body shape of P. pruinosus as a response to seasonal variations, (ii) determine differences in the body shape during ontogeny, (iii) examine the effect of intraspecific allometry to interpret the observed variations in the species, and (iv) clarify whether the body shape of P. pruinosus can be used as a sexual differentiating trait. Results Juveniles showed no seasonal variations in the body shape, which were detected among adults, females and males as shown by PCA, DFA, and MANOVA. The adult winter forms have large bodies, small heads, broad pereons, and short but wide telsons. The adult summer forms have small slender bodies, slightly stretched heads, and relatively long telsons. Juveniles’ growth to adulthood showed body shape changes in the head and pereon, that include shrank of the head in the anteroposterior direction and its level became slightly lower than the body. The pereon becomes broader and the two anterolateral projections of the first pereonite extend anteriorly, reaching a little beyond the posterior margin of the eyes. Present species showed a shape sexual dimorphism which includes the broader body and more convex pereon in females and a small waist between the second and third pleonites in males. Shape sexual dimorphism was attributed to reproductive activity. Both allometric trajectories of juveniles and adults (ontogenetic allometry) and of sexes (static allometry) were parallel. Conclusions The landmark geometric morphometric technique was able to reveal the seasonal shape variations in terrestrial isopod P. pruinosus . Also, this method provides information about shape variations between juveniles and adults, as well as about shape sexual dimorphism.

This was regarded by KESSELYAK and VANDEL as a remainder of the primitive duality, while MACCAGNO and VERHOEFF as a secondary condition due to the coaptation at the endopodites of the first pleopode (VANDEL, 1962). In both cases, the clear difference of the section Crinocheta from the Monospermophora is obvious. ...

In this first note, we present the taxonomic position and the differential diagnosis of the family Trichoniscidae. In our opinion from the common ancestor of Oniscidea two lineages evolved: a lineage evolved toward the complete disappearance of the genital apophyses leaving only two separated male genital openings (Infraorder Tylomorpha) while the other lineage evolved toward merging the two genital apophyses up to the fusion of the ejaculatory ducts and a single genital opening (Infraorder Ligiamorpha). Within Ligiamorpha, the family Trichoniscidae is included in Suprasection Orthogonopoda, Section Synocheta. We argue for the sister group relationship of Section Synocheta with Microcheta (Mesoniscidae) and not with Crinocheta, the most evolved group among the terrestrial Isopods.

The capability of producing sounds and vibrations is well known in insects and is thought to be a form of intra- and interspecific communication. Sounds and vibrations are used and modulated for several aims such as interacting with conspecifics, getting information from the environment, and defending against predators. This phenomenon is less known but also present in other arthropods, including a few roller-type terrestrial isopods. In this study, we used a Y-shape test apparatus to investigate the behavior of adult individuals of Armadillo officinalis Duméril, 1816 (Crustacea: Isopoda: Oniscidea) when exposed to two particular vibrational stimuli, namely species-specific stridulations, and non-specific substrate-borne vibrations. Our results showed that adults of A. officinalis significantly react to the presence of both types of vibrational stimuli, by moving away from the vibrational source as if they experienced these vibrations as a sign of danger or disturbance. A. officinalis can produce stridulations only when it rolls into a ball during the so-called conglobation, a possible defense mechanism against predators. Stridulation might thus be a secondary form of defense used during conglobation to deter a predator following contact with it and might be experienced as an alert by conspecifics nearby. The high sensitivity to non-specific substrate-borne vibrations might provide A. officinalis with the possibility to anticipate dangers and adverse conditions, giving it a better chance of survival.

Species richness of terrestrial isopods is high in caves of the Dinaric Karst, which hosts ~10% of the world’s nominal oniscidean troglobionts. The most widespread taxon is the southern European genus Alpioniscus, which consists of two subgenera: Alpioniscus s.s. and Illyrionethes. Before this study, 14 nominal troglobiotic Illyrionethes taxa were recorded from the Dinaric Karst. Our molecular analyses using two mitochnodrial DNA (16S rRNA and COI) fragments and a nuclear gene (H3) fragment on all known Dinaric taxa identified three distinct lineages: strasseri-, heroldi- and magnus-lineage. Our results confirmed the validity of most nominal species. The exceptions are Alpioniscus balthasari, which consists of two different species including Alpioniscus iapodicus, and Alpioniscus heroldi, which is paraphyletic with respect to Alpioniscus bosniensis. The strasseri-lineage was highly supported by all phylogenetic methods used; therefore, we performed a detailed morphological analysis to distinguish and characterize the species of this group. New morphological characters, such as body part ratios, are proposed for future species identification. In addition, we redescribe three known species (Alpioniscus strasseri, Alpioniscus christiani and Alpioniscus balthasari) and describe two new ones (Alpioniscus hirci sp. nov. and Alpioniscus velebiticus sp. nov.). As a result, 15 nominal species of Illyrionethes are currently known from the Dinaric Karst.

Woodlice (Isopoda: Oniscidea) represents a group of arthropods that has been neglected in Switzerland. The last comprehensive review on Swiss woodlice was published more than a cent ury ago. In the present work, we update the checklist of woodlice in Switzerland and provide information on the distribution of each species as well as further remarks. We considered information on recent records of woodlice from different regions and habitats of Switzerland and present new species records, which are mainly based on a survey of heated reenhouses in nine botanical gardens and other institutions across Switzerland and a fi eld survey in the Swiss National Park. Altogether, we found six new species for Switzerland. Five of them are exotic species, captured so far exclusively in heated greenhouses: Reductoniscus costulatus Kesselyák, 1930, Venezillo parvus (Budde-Lund, 1885), Chaetophiloscia cellaria (Dollfus, 1884), Nagurus cristatus (Dollfus, 1889), Buddelundiella cataractae Verhoeff, 1930b, and Miktoniscus linearis (Patience, 1908). Thus, the updated checklist of terrestrial woodlice in Switzerland comprises 50 species.

Dispharynx nasuta is a widespread nematode parasite located in the proventriculus. This parasite may cause mortality in free-living birds or in captivity. However, reports of this parasite in psittacines are scarce. In a private aviary, in Zamora, Michoacan, Mexico six red-rumped parrots (Psephotus haematonotus) died in one month, from mid-August to mid-September 2016, and one more specimen died during the examination. Prior to death, the birds presented depression, ruffled feathers, crop atony, and regurgitation. Upon necropsy, ulcers in the proventriculus, and hemorrhagic content associated with the presence of round worms was observed. At histopathology examination, the parasites were identified as Spirurida nematodes, located in the proventricular and ventricular mucosa. Specimens were submitted to the parasitology laboratory of the College of Veterinary Medicine and Husbandry, National Autonomous University of Mexico (UNAM), where the parasites were identified as D. nasuta. This is the first report of D. nasuta in P. haematonotus and the first report of D. nasuta in Mexico.

Terrestrial isopods (Crustacea: Isopoda: Oniscidea) from Bosque Fray Jorge National Park, Coquimbo Region, Chile. The Bosque Fray Jorge National Park, located in the coastal mountain range of the Coquimbo region, occupies an area of arid mediterranean climate with marine influence, dominated by vegetative formations of desert scrub and with presence of forested relics associated with peaks exposed to coastal fogs. This work describes the terrestrial isopod fauna of the Bosque Fray Jorge National Park based on material obtained during two campaigns carried out in 2017. The surveys were successful only in damp microhabitats, such as the rocky supratidal, mist forests, water bodies and springs associated with human settlements. A total of 12 species, distributed in 11 genera and 9 families were registered, which constitutes an increase of 92% in the local oniscofauna diversity. A half of the isopods species collected are exotic, while among native species, at least two of them have not been described.The exotic species Haplophthalmus danicus is the first representative of the family Trichoniscidae known in Chile, while Platyarthrus aiasensis and Trichorhina tomentosa are the first myrmecophilous species. On the other hand, although Porcellionides pruinosus and Armadillidium vulgare had already been recorded in the country, these are the first known locations in continental Chile. Finally, the exotic species Niambia capensis is cited for the first time in areas far from marine influence. Among the native isopods, only Chileoniscus marmoratus had previously been registered in the park. However, the presence of Benthanoides sp., Ligia novizelandiae and Tylos chilensis are confirmed, because these species have been previously reported in locations northern and southern the study area. The record of the family Dubioniscidae requires confirmation, as it is based on incomplete material. This work has allowed to add five species to the Chilean oniscofauna, so the diversity of the group would reach a total of 15 families, 27 genera and 50 species in the country.

The study focused on the attractiveness of mulches (consisting of the addition of a layer material to the soil surface) and their efficiency to promote recolonization by pedofauna of isolated and degraded areas. The experimental study was set up in the former coal mining area of Northern France. This area is particularly disturbed and fragmented by land-use change, urbanization, industry, intensive agriculture and metal pollution. To examine the movements of pedofauna, four kinds of mulches were applied: (i) Ramial Chipped Wood (RCW), (ii) chopped Miscanthus, (iii) dead leaves and (iv) wheat straw as well as plastic sheeting, a material often used in green spaces. A negative control consisted in soil without mulch addition. The experimental set-up consisted of a set of 18 bands of mulch (6 m long x 0.5 m width x 8 cm thick, i.e. a volume of 0.04 m3 per band) installed on three adjacent plots on a surface area which stretch on 4400 m2: (i) plot F1, a mixed plantation, (ii) plot M consisted of three rows of maples (both considered to be the reservoir of biodiversity) and (iii) plot BF, an ash plantation (with lower biodiversity). Faunistic communities of soil present within the mulches were monitoring using pitfall traps for four months (April to July), at a rate of eight surveys for each of the 90 traps installed, i.e. 720 samples. Different life traits and indices of diversity were studied, more specifically on carabid beetles. The main objective of the study was first to check whether mulches could or not reconnect different planted plots in a peri-urban landscape highly modified by human activities. The second aim was to find which type of mulch had the best efficiency in the recovery of the connectivity between plots. The last questions were which type of zoological groups could be favoured by the use of mulches and which benefits for ecosystem functioning. The main hypotheses of this study were: (i) Organic mulches would act as dispersal corridors and refuge zones to the soil organisms; (ii) organic mulches would be attractive to many organisms with various ecological needs. This study highlighted the potential benefits of using the mulching technique to support ecological connectivity in disturbed environment since this method highlighted the presence of individuals with different diets (saprophagous, predators, phytophagous and so forth), small and large size species which do not have the same dispersal capacities as well as species that are more dependent on forest environments and others that depend on more open environments. The study concluded that organic mulches are more favourable to pedofauna than soil without mulch or plastic sheeting. With regard to organic mulches, no difference was noted, either in terms of cumulative abundance or monthly monitoring. However, for carabids, it should be noted that dead leaves and wheat straw have higher specific richness than Miscanthus and RCW.
