A cladistic analysis of the genus Atlantodesmus Hoffman, 2000 is presented. With a total 11 taxa and 30 morphological characters, under implied weighting (k = 3), two equally most parsimonious trees (length 58 steps; fit 23.150; CI 0.64; RI 0.64) recovered monophyly genus. The resulting synapomorphies are: absence ventral projection on post-gonopodal sternites; presence folds dorsal edge prefemoral region gonopod; one homoplastic transformation: cingulum. In addition, sierwaldae sp. nov....

Chelodesmidae is one of the most diverse families belonging to Polydesmida, comprising almost 800 described species distributed in 172 genera, 20 tribes and two subfamilies. Among within Neotropical subfamily Chelodesminae, Arthrosolaenomeridini represents a very interesting group occurring Central-West region Brazil. Currently tribe contains three genera: Arthrosolaenomeris Schubart, 1943, Gangugia 1947, Angelodesmus 1962. In this study, we conducted cladistic analysis including 18 7 other...

ABSTRACT The millipede Chondromorpha xanthotricha, supposedly native to Sri Lanka and southern India, is considered a pantropical species occurring in Southeast Asia, North America, Mesoamerica, the Caribbean, Central America northern South America. Here we report first record of this for Brazil, central Amazon region country, with taxonomic notes images male female specimens.

A checklist of the family Chelodesmidae Cook, 1895 (order Polydesmida) from state São Paulo, Brazil has been performed based on literature and examined material collection Instituto Butantan, Paulo (IBSP). total 15 genera (7 tribes 5 considered incertae sedis) with 64 species are listed. Among these species, 30 presented a single one record in state, 19 more than four recorded for first time 11 occurring other Brazilian states. The most distributed is Brasilodesmus paulistus (Brölemann,...

The present study provides historical and new records of the introduced millipedes species in Brazil, Oxidus gracilis (C.L. Koch, 1847), Orthomorpha coarctata (Saussure, 1860) (Paradoxosomatidae), Prosopodesmus jacobsoni Silvestri, 1910 (Haplodesmidae), Trachyjulus calvus (Pocock, 1893a), Glyphiulus granulatus (Gervais, 1847) (Cambalopsidae), Trigoniulus corallinus 1842), Leptogoniulus sorornus (Butler, 1876), Epitrigoniulus cruentatus (Brölemann, 1903) (Pachybolidae), Paraspirobolus...

The Amazonian genus Parastenonia Hoffman, 1977 is here revised. species P. carajas sp. nov. described from Brazilian iron-ore caves and aurae (Schubart, 1947) considered junior synonym of parae (Cook, 1895). In addition, the known geographic distribution presented with inclusion new occurrence data.http://www.zoobank.org/urn:lsid:zoobank.org:act:CCBEED10-DCB4-48C9-A71D-CED3462DD72A

This study concerns the millipede genus Leptherpum Attems, 1931, which contains nine valid species distributed across Amazonian rainforest of northeastern South America. The type L. carinovatum (Attems, 1898) is reexamined based on material and high-resolution photographs, including first scanning electron micrographs this species. following three new are described: tialaura sp. nov. from state Pará, Brazil; battirolai Amazonas, buenovillegasi commune Maripasoula, French Guiana. A brief...

In order to provide a reassessment of the Neotropical genus Pseudonannolene Silvestri, 1895, cladistic analysis, biogeographic and taxonomic review were conducted in present work. For approach, 91 morphological characters scored for 53 terminals as ingroup 10 outgroup. Three synapomorphies support monophyly genus: presence longitudinal suture on promentum, penial bases partially fused, internal branch gonopods surrounding telopodite; two homoplastic transformations: lateral lobe collum...

ABSTRACT The South American genus Heteropyge Silvestri, 1897 is revised, accommodating now six accepted species. Adults of the poorly known species araguayensis (Schubart, 1947) are described for first time from near-topotypic material collected near Araguaia River, state Mato Grosso, Brazil. In addition, based on recent samplings and Schubart’s collection, H. bidens 1945) removed synonymy cayennophilus (Silvestri, 1897) revalidated. Both show significant differences concerning gonopods male...

A new genus and two species of Chelodesmidae are described from caves the Joo Rodrigues river system in Bahia state, northeastern Brazil: Strongylosomides troglobius sp. nov. Rotundotergum elevatum gen. nov., The former differs congeners primarily by gonopods showing prefemoral process strongly fused caudally along its basal half to acropodite and, such troglomorphic traits as a nearly unpigmented fragile body with thin tegument, it seems first troglobiont be documented genus. Moreover, this...

New records for the species Exallostreptus vanzolinii Hoffman, 1988 and Guaporeptus paradisius 1988, known only from state of Rondônia, are made Mato Grosso, Brazil. Figures gonopods, first second leg-pair males provided. In addition, an updated list 19 Spirostreptidae Grosso is provided, with Plusioporus salvadorii, Trichogonostreptus (Oreastreptus) mattogrossensis, Urostreptus tampiitauensis widely distributed in state.

Chelodesmidae is one of the most species rich families within Myriapoda. However, little known regarding their association with caves. We provide a list all taxa reported from caves, map worldwide distribution, and discuss troglomorphic features group. A total 25 subspecies 20 genera 2 subfamilies have been recorded 59 caves cave systems in 11 countries. These numbers represent surprisingly modest proportion (~3%) approximately 800 described family. Records cave-dwelling chelodesmids appear...
