“…Eucampesmella was recovered as a sister-group of Telonychopodini, whereas the relationship of Macrocoxodesmus to Rondonaria + Odontopeltis was well-supported. In addition, the structure of the gonopodal aperture in Eucampesmella is similar to the condition found in members of Telonychopodini (Hoffman 1965, 2000, 2005, Pena-Barbosa et al 2013. Concerning the female characters, Macrocoxodesmus marcusi has a modified legpair associated with the vulva, a condition only known in Macrocoxodesmus and Plectrogonodesmus gounellei (Bouzan et al 2019a).…”

This study concerns the diplopod genus Eucampesmella Schubart, 1955, widespread in Brazil. After this work, the genus includes 12 valid species, and three incertae sedis: E. pugiuncula (Schubart, 1946), E. brunnea Kraus, 1959 and E. schubarti Kraus, 1957. The type-species, Eucampesmella tricuspis (Attems, 1931), is redescribed based on the holotype, and the following six new Brazilian species are added: Eucampesmella macunaima sp. nov. from the states of Rondônia, Pará, and Piauí; E. capitu sp. nov. from the states of Piauí and Paraíba; E. brascubas sp. nov. from the state of Sergipe; E. iracema sp. nov. from the state of Pernambuco; E. pedrobala sp. nov. from the state of Ceará; and E. lalla sp. nov. from the state of Rio Grande do Norte. Furthermore, E. lartiguei ferrii (Schubart, 1956) is recognized as a junior synonym of E. lartiguei lartiguei (Silvestri, 1897), which also had its status changed, and E. sulcata (Attems, 1898) is revalidated, prevailing under the name Leptodesmus tuberculiporus Attems, 1898. In addition, drawings, diagnoses, and distribution maps for all species of the genus are provided.

“…Catharodesmus ), and Brachyurodesmus (not reallocated to another tribe), placing Macrocoxodesmus and Eucampesmella into the new tribe Macrocoxodesmini (Hoffman, 1990a), and adding the genus Pantanalodesmus Hoffman, to the Telonychopodini. The last additions to Telonychopodini are the genera Vanzolegulus Hoffman, and Dioplosternus Hoffman, (not included in this data set). Finally, Hoffman () provided a new diagnosis for the tribe, characterized mainly by the elongated cyphopod projecting ventrally, the large sclerotized sternum of the male gonopod ring, with or without a prefemoral process in the gonopod, and the presence of rounded paranota without projections.…”

On the largest chelodesmid millipedes: taxonomic review and cladistic analysis of the genusOdontopeltis Pocock, 1894 (Diplopoda; Polydesmida; Chelodesmidae)

2013

The chelodesmid genus Odontopeltis Pocock, 1894, is revised. It currently contains eight species, four of which are described as new here: Odontopeltis aleijadinho sp. nov., Odontopeltis donabeja sp. nov., Odontopeltis tiradentes sp. nov., and Odontopeltis xica sp. nov. Additional descriptive data are provided for Odontopeltis anchisteus Hoffman, 1981, Odontopeltis clarazianus (Humbert & deSaussure, 1869), Odontopeltis giganteus Schubart, 1849, and Odontopeltis conspersus (Perty, 1844); for the latter species a neotype is designated herein. The current position of all species ever associated with the genus is presented. Examination of type material revealed that the following species are not members of the genus Odontopeltis: Odontopeltis balzanii Silvestri, 1895, Odontopeltis borellii Silvestri, 1895, Polydesmus gracilipes Humbert & deSaussure, 1870, and Odontopeltis proxima Silvestri, 1895. The type specimen of Rhacophorus decoloratus Koch, 1847, is lost and the species is considered incertae sedis. The terminology of gonopod structures is discussed. A phylogenetic analysis of Odontopeltis based on 47 morphological characters, with species of the genus Odontopeltis and six outgroup taxa is presented. Odontopeltis is monophyletic, with Rondonaria as its closest sister-group. The included members of the tribe Telonychopodini (Pantanalodesmus, Telonychopus, and Manfrediodesmus) form a monophyletic group; the tribe Macrocoxodesmini (Macrocoxodesmus and Eucampesmella) is paraphyletic in this data set.

“…– After the Paradoxosomatidae, the family Chelodesmidae is one of the most diverse polydesmidan group comprising 230 extant genera with nearly 450 species [31] , whose distribution now extends to Africa, Middle America and South America [28] . At the present time, there are five living species of the Chelodesmidae recorded in Mexico assigned to the genera Chondrodesmus, Rhaphandra and Eutyporhachis , the latter is also present in the Chiapas Highlands [32] – [33] .…”

Two Flat-Backed Polydesmidan Millipedes from the Miocene Chiapas-Amber Lagerstätte, Mexico

et al. 2014

View full text Add to dashboard Cite

Two species of fossil polydesmidan millipedes (Diplopoda: Polydesmida) embedded in amber are described from Miocene strata near Simojovel, in the Chiapas Highlands, Mexico. Maatidesmus paachtun gen. et sp. nov., placed into Chelodesmidae Cook, 1895, and Anbarrhacus adamantis gen. et sp. nov., assigned in the family Platyrhacidae Pocock, 1895. Morphological data from fossil specimens have been recovered using 3D X-ray micro-computed tomography and regular to infrared-reflected microscopy. Both fossil species are recognizable as new primarily but not exclusively, by collum margin modification and remarkable paranotal and metatergite dorsal sculpture.
