Three species of Myriapoda new for metropolitan France. Two species of diplopods, Cylindroiulus britannicus (Verhoeff, 1891) (Diplopoda: Julida) and Amphitomeus attemsi (Schubart, 1934) (Diplopoda: Polydesmida) and one of chilopod, Tygarrup javanicus Attems, 1907 (Chilopoda: Geophilomorpha), have recently been discovered in metropolitan France. A d...
The Écrins National Park (PNE), a high mountain territory with several peaks reaching more than 3000 meters above sea level, is very diverse in terms of landscape, geology and local climate. The first inventories of diplopod arthropods (Class Diplopoda de Blainville in Gervais, 1844) of the Écrins national Park were carried out by Jean-Jacques Geof...
Un inventaire de la faune invertébrée vivant dans le sol et dans les mousses corticoles a été mené dans deux forêts, situées dans la Réserve naturelle nationale du Marais de Lavours et la Réserve naturelle régionale de la Galerie du Pont des Pierres (Département de l’Ain). Au total, 32 338 spécimens ont été collectés, correspondant à trois phylums...
La faune des Chilopodes de France métropolitaine comporte actuellement 154 taxons terminaux : 151 espèces et trois sous-espèces, dont la liste commentée est fournie dans le présent article. Stenotaenia sorrentina (Attems, 1903) est confirmée en France (Corse). Les spécimens autrefois cités comme Lithobius nodulipes Latzel, 1880 en Corse se rapporte...
The soil-dwelling (endogeic) centipede Lithobius lemairei has been observed in the gardens of the Villa Paradiso in Nice (Alpes-Maritimes, France). Some criteria are briefly described and the species is transferred to the subgenus Sigibius Chamberlin, 1913. Several determinant species of soil-dwelling beetles have also been found in the same statio...
Presentation of the Myriapoda with biological and ecological details on the chilopods and diplopods of the Bouches-du-Rhône department (Provence-Alpes-Côte d'Azur region, France). Presentation of conservation issues of chilopods and diplopods, with examples of some species found to be threatened in this region.
Several field investigations have been conducted for the centipedes
of the area of Païolive and its surroundings (Ardèche) during 2009 and 2015 to 2018. A new French endemic Lithobiomorpha is described: Lithobius (Lithobius) aberlenci n. sp. This species is potentially troglophile. Several specimens of L. (L.) peregrinus Latzel, 1880, have been fou...
Dans le cadre d'un inventaire des invertébrés présents dans les serres du Parc Phoenix, à Nice (Alpes-Maritimes, France), un diplopode pénicillate connu d'Italie mais nouveau pour la France, Lophoproctus coecus Pocock, 1894, a été observé dans une serre tempérée. Cette découverte porte à 7 le nombre d'espèces de l'ordre Polyxenida en France métropo...
The hitherto monotypic diplopod genus Annamina contains now four species, including the revised typespecies A. xanthoptera Attems, 1937, as well as A. attemsi sp. n., A. irinae sp. n. and A. mikhaljovae sp. n., all from central or southern Vietnam. The genus is rediagnosed and a key to its constituent species given.
The purpose of this work, under Articles 23.9.1.1, 23.9.1.2, 23.9.2, 52.5, 54.4 and 82.2.1 of the International Code of Zoological Nomenclature, is to conserve the specific combination and authority Polydesmus denticulatus C.L. Koch, 1847, which is in widespread use for a millipede species belonging to the family Polydesmidae. The name is jeopardiz...
In biodiversity management, spatio-temporal heterogeneity is important to consider conserving high levels of habitat diversity and ecosystems. In this study, we investigated the relationship between landscape spatio-temporal heterogeneity and biodiversity in a mosaic-landscape, located in the Fontainebleau forest (France). The diversity of successi...
The small-bodied millipede, Myrmecodesmus hastatus (Schubart, 1945), which seems to be strongly associated with ant and termite nests, and currently populates much of South America, is recorded from Martinique for the first time. Abundant, mostly SEM illustrations are provided to facilitate its recognition. This record strongly extends its distribu...
Millipedes (classs Diplopoda) are terrestrial saprophagous arthropods. This paper gives a short description of their classification, biogeography, anatomy and physiology, mainly focusing on problems faced by diplopods in freshwater. Some 'subaquatic' species are well adapted to water and can survive long periods of submersion. Particular cases are...
The Myriapoda and Onychophora collection dataset inventories the occurrence records of the collection of myriapods and onychophorans in the Muséum national d’Histoire naturelle, Paris. The dataset currently consists of 202 lots of onychophorans, representing all of those present, and almost ten thousand (9 795) lots of myriapods, representing 33 to...
Moderate grazing by cattle increases the heterogeneity of soil and vegetation. This has been suggested as an ecologically sustainable mean of managing natural environments endangered by tree encroachment, such as heathlands. Our study was performed to test the impact of grazing intensity on soil macroinvertebrate communities in heterogeneous landsc...
The Eutrichodesmus fauna of mainland China, by far the largest genus in the Indo-Australian family Haplodesmidae, is reviewed and shown to encompass 23 species (of a total of 45), all keyed. The following nine new species, all presumed troglobites, are described: E. triangularis sp. n., from Sichuan, E. lipsae sp. n., from Guangxi, E. tenuis sp. n....
Suite à l'examen de nombreux spécimens, les auteurs exposent des données nouvelles sur les chilopodes du Parc national du Mercantour, du département des Alpes-Maritimes et de leurs environs. Ces observations améliorent la connaissance de la répartition de certaines espèces rares et localisées et permettent en outre de décrire une nouvelle espèce en...
After the examination of many specimens, the authors give new data on centipedes of the Mercantour National Park, the Alpes-Maritimes department and their surroundings. These examinations improve the knowledge of the distribution of several fairly rare species and allow to describe a remarkable new species from Entrevaux (Alpes-de-Haute-Provence de...
In the Oriental Region, the large, basically Northern Hemisphere family Trichopolydesmidae is shown to currently comprise 18 genera and 43 species. Based mainly on gonopod structure, all of them, as well as the whole family, are (re)diagnosed, including five new genera and seven new species. These new taxa are keyed, also being the first to be desc...
A new species of the rather large, basically tropical/subtropical Asian genus Cryptocorypha is described from the Espíritu Santo Island, Vanuatu: C. chernovi sp.n. This is the 12th species in the genus and the second member of Pyrgodesmidae presumably endemic to Vanuatu. It differs from all sufficiently well described congeners but C. stylopus Atte...
Four new species of the large, mostly Papuan genus Eustrongylosoma are described from the Espiritu Santo Island, Vanuatu: E. hirsutum sp.n., E. vanuatu sp.n., E. acutum sp.n. and E. picturatum sp.n. These are only some of the species of the genus that actually populate the island. Besides Eustrongylosoma, Espiritu Santo seems to fail to support any...
Glomeridae in the fauna of Vietnam appear to show a remarkably high rate of endemism (100 and 60% at the species and generic levels, respectively) and currently encompass 17 unquestioned species in five genera, including Hyleoglomeris cavernicola sp.n., H. spelaea sp.n., H. colorata sp.n. and Hyperglomeris depigmentata sp.n.
The small, basically Oriental family Opisotretidae is rediagnosed, reclassified, and shown to comprise the following seven genera, all keyed: Carlotretus Hoffman, 1980, with two species, including C. triramus sp. n. from southern China; Corypholophus Attems, 1938, with two species, one in Vietnam, the other in the Ryukyus, Japan; Martensodesmus Gol...
Two new pigmented species of the large, basically warm temperate to tropical Eurasian genus Hyleoglomeris are described from Nusakambangan Island, a small island off the southern coast of Java, Indonesia: H. contrasta sp.n. and H. fusca sp.n. Both differ from congeners, including H. jacobsoni (Silvestri, 1917), the sole species of the genus hithert...
China is shown to currently support 23 species of the large, basically warm temperate to tropical Asian genus Hyleoglomeris, all keyed and mapped, including 15 new ones: H. tiani sp. n., H. xia sp. n. and H. youhao sp. n. from Hunan Province, H. wuse sp. n., H. nigu sp. n., H. gudu sp. n. and H. yinshi sp. n. from Guizhou Province, as well as H. qi...
The large genus Trachyjulus, in which endemic species range from Sri Lanka and India in the west, through Indochina and the Himalaya, to Malay Peninsula and Indonesia (Sumatra and Java), in the east, currently encompasses 31 species, including four new: 7. beroni sp.n. and 7. subcalvus sp.n., both from Malaysia, as well as 7. unciger sp.n. and 7. p...
The small, basically Himalayan genus Glenniea Turk, 1945 is formally new to the fauna of China due to the discovery of G. prima sp.n., a species that lives epigeically in Guangxi Province. Epanerchodus orientalis Attems, 1901, a highly polymorphous species very common in Japan and Taiwan, is formally reported from China for the first time as well,...
The large Southeast Asian genus Desmoxytes is slightly rediagnosed. A number of troglomorphic, most likely troglobitic, species occur in southern China. A key is provided to all 10 Desmoxytes spp. currently known from China, including three new presumed troglobites: Desmoxytes eupterygota
sp. n. from Hunan Province, as well as Desmoxytes spinissima...
The number of stadia during post-embryonic development is supposed to be fixed in most species of the millipede order Polydesmida. For the first time since 1928, additional moults were observed in two males of Polydesmus angustus Latzel, 1884 reared in the laboratory. These 'elongatus' males sensu Verhoeff reached stadium IX instead of stadium VIII...
Two new species of the families Polyxenidae and Synxenidae, are described from Table Mountain National Park, South Africa. Propolyxenus squamatussp. n. (Polyxenidae) has tergites I-X mostly covered by scale-shaped trichomes directed caudally, a character previously known only in Synxenidae. The structure of scale-shaped dorsal trichomes is differen...
