... Si bien señala que este grupo ocupa una posición particular, tanto por la ausencia de diferenciación sexual en el 7º pereiópodo del macho, como por la alta diferenciación del endopodito del segundo pleópodo del macho. Algo semejante podemos indicar para T. sicoensis Reboleira & Taiti, 2015, ya que Reboleira et al. (2015 apuntan la posibilidad de que pueda pertenecer a un género diferente. Ambas especies, T. albigensis y T. sicoensis, comparten algunos caracteres, como la gran membrana hialina del segundo endopodito del pleópodo de macho o las estriaciones que adornan su extremo. ...

Pero difieren en otros como la forma del exopodito del pleópodo I del macho, rectangular, mucho más ancho que largo, y con una escotadura en la base de los tallos ciliados, y sin diferenciación sexual en el pereiópodo 7º del macho en T. albigensis, frente al exopodito cuadrangular, sin escotadura y 7º pereiópodo diferenciado en T. sicoensis. También se puede indicar que en ambas especies, la punta del endopodito II del macho termina de forma muy diferente (Dalens, 1966;Reboleira et al., 2015). Trichoniscoides basozaina sp. ...
A new species of terrestrial isopod of the Trichoniscidae Sars, 1899 family, Trichoniscoides basozaina sp. nov., found in the Otxola's cave (Navarra) is described, and its diagnostic characteristics are discussed, and also its similarity with the other species of the genus are discussed. The structure of the endopod of the second male pleopod places it in the group of species that served as a transition bridge between the "pyrenean" group of Trichoniscoides Sars, 1899, and the pyrenean genus Scotoniscus Racovitza, 1908.

The genus Eluma Budde-Lund, 1885, was composed until now by three species, with a Betic-Rif distribution type. In this work a new species of the genus is described, Eluma matae sp. nov., from the West region of Portugal. The distribution of the two other known species present in the Iberian Peninsula is updated, and figures of the three Iberian species are provided to facilitate their identification. Finally, a dichotomic key for the entire Eluma genus was also created.
... As corrections to the given illustrations, I present SEM of relevant details of S. rubens males (Fig. 7) which fully correspond to the precise drawings of this species in Juberthie (1967). There are some cases of the spread of some old Aegean fauna into western Mediterranean, as in terrestrial isopods Graeconiscus (Garcia et al. 2020), Cordioniscus (Reboleira et al. 2015), Macedonethes (Karaman 2003), cave cricket genus Dolichopoda (Karaman et al. 2011) and probably others. Assuming a sympatrical occurrence of species at the locality of Mt Aigual in France (cited as the source of the analyzed samples in de Bivort and Giribet 2004), and thanks to the published coordinates in Giribet and Shear (2010), I found only relatively numerous populations of S. rubens. ...

Abstract Spelunconiscus Campos-Filho, Araujo and Taiti, 2014 is a monotypic genus of the family Styloniscidae represented by a troglobitic species, Spelunconiscus castroi Campos-Filho, Araujo and Taiti, 2014, from the cave MOC-32, in the state of Minas Gerais, southeastern Brazil. New representatives of this family were found in three additional caves, which revealed a new species, Spelunconiscus septemlacuum sp. nov., from Taboa and Tatuzinhos caves and a new occurrence for the type-species in Retiro cave. The original diagnosis of Spelunconiscus is emended due to the discovery of a spur-like structure in the male pereopod VII ischium, as well as some supplementary traits that have not been previously considered. Spelunconiscus septemlacuum sp. nov. differs from S. castroi in the number of articles of the antennal flagellum, in the proportion between this flagellum and 5th article of peduncle of antenna, in the size of maxilliped endite, in the morphology of male pleopod II and in body size. A discussion is provided for both taxonomic and ecological concerns.
... Mais de três dezenas de novas espécies foram descritas e novos padrões biogeográficos foram estabelecidos (Reboleira, 2012).

O Planalto das Cesaredas é formado por calcários marinhos do Jurássico Inferior a Superior (Toarciano ao Titoniano, ~180 a 144 milhões de anos) e alberga várias cavidades naturais com condições propícias à vida subterrânea. Localizado a baixa altitude na transição entre o maciço de Montejunto e vale Tifónico das Caldas da Rainha, este afloramento cársico inclui-se no distrito bioespeleológico Lusitânico, unidade biogeográfica que inclui os maciços da Arrábida, Estremenho, Sicó-Condeixa-Alvaiázere, Outil-Cantanhede e os afloramentos calcários da Península de Lisboa. O interesse científico sobre a biologia das grutas das Cesaredas teve o seu despertar há sete décadas e investigações recentes revelaram que a sua fauna estritamente subterrânea é composta sobretudo por invertebrados: moluscos, aracnídeos, miriápodes, crustáceos e insectos. A descoberta de espécies endémicas, i.e., cuja única área de distribuição mundial se encontra confinada ao Planalto das Cesaredas, lança grandes desafios em termos de conservação e urge estabelecer medidas de proteção para salvaguardar a sua biodiversidade subterrânea. Este artigo oferece uma perspectiva sobre a geologia, composição faunística e a ecologia das grutas das Cesaredas.
... Despite some recent studies (e.g. Gregory et al., 2012;Reboleira et al., 2015;Cifuentes, 2019a, b;Marmaneu et al., 2019), the terrestrial isopod fauna of the Iberian Peninsula is still poorly studied, and new undescribed species are likely to be found in the region, including troglophilous-like species even in sandy areas, as is the case of the new myrmecophilous species presented here. ...
... Current taxonomy of the family Armadillidiidae recognizes 17 genera (Schmalfuss, 2003;Schmidt & Leistikow, 2004;Reboleira et al., 2015), including Iberiarmadillidium described here. Most of them are poorly diversified, usually with fewer than ten species, including several monotypic genera and with limited geographical ranges. ...
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.

This study is the first kind of it in Iraq. The samples were collected from April to Junuary 2018, we recorded seven species for the first time in Iraq ( Procellio laevis, P. cingendus, Lacasius pallidus, Armadillidium album, A. assimile, Orthodillo chiltoni, Cylisticus convexus ). These species belong to four famillies (Procellionidae, Armadillidae, Armadillidae, Cylistieidaeà). The samples were saved in the natural histroy museum in Baghdad-Iraq.
... In Portugal the MSS habitat was first studied in the islands of Madeira (Oromí and Borges, 1991) and Azores (Borges, 1993), while in continental Portugal only a millipede and an isopod species have been reported from the MSS (Reboleira and Enghoff, 2014;Reboleira et al., 2015). Portugal is one of the Mediterranean biodiversity hotspot regions for subterranean organisms (Reboleira et al., , 2013b and the MSS habitats found in Portuguese karst areas are classified as western Mediterranean and thermophile deposits protected by the Natura 2000 network, under the 92/43/CEE directive (EU, 1992;ICNB, 2000). ...
The mesovoid shallow substratum (MSS) can act as a climatic refuge for invertebrates, as a biogeographic corridor to deeper substrates or as a permanent habitat for some species. This study characterizes the seasonal invertebrate diversity and abundance of MSS ecosystems in central Portugal focusing on Diplopoda, Diplura, Orthoptera and Coleoptera during one year. Sampling was performed with standard MSS pitfalls in scree slopes (colluvial MSS) of karst areas and environmental parameters (temperature, pH, conductivity, water content, organic carbon, nitrate, phosphate and ammonium) were quantified. Our results show that winter was the season with the highest arthropod abundance and that the MSS acts as a permanent habitat for chordeumatidan millipedes and as a climatic refuge for orthopterans and most beetles. All Diplura collected belong to a single species known previously from surface habitats in the Iberian Peninsula, which does not seem to use the Portuguese MSS as a refuge. MSS habitats in central Portugal, classified as western Mediterranean and thermophile deposits protected by the Natura 2000 network based on plant communities and geology, revealed an abundant and diverse invertebrate community that urges characterization and protection.
