“…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). Further studies are still required to confirm the tribal position of Eucampesmella.…”

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.

“…Other variations within the Xystodesmidae are known, such as in the genus Cherokia Chamberlin, 1949, which lacks a receptacle entirely (Hoffman 1960) and the genus Pachydesmus Cook, 1895, in which females have modified cyphopodal apertures and receptacles (Hoffman 1958). Other families of Polydesmida are also known to have modified female genitalia, such as the Chelodesmidae, with the species Plectrogonodesmus gounellei (Brölemann, 1902) having an enlarged epigyne and recurved receptacles with tubular projections (Brölemann 1902;Bouzan et al 2019). In the Polydesmidae, Pseudopolydesmus Attems, 1898 has recently-identified cyphopod structures that may be useful for species identification (Zahnle et al 2020).…”

Although many new species of the millipede genus Nannaria Chamberlin, 1918 have been known from museum collections for over half a century, a systematic revision has not been undertaken until recently. There are two species groups in the genus: the minor species group and the wilsoni species group. In this study, the wilsoni species group was investigated. Specimens were collected from throughout its distribution in the Appalachian Mountains of the eastern United States and used for a multi-gene molecular phylogeny. The phylogenetic tree recovered Nannaria and the two species groups as monophyletic, with Oenomaea pulchella as its sister group. Seventeen new species were described, bringing the composition of the wilsoni species group to 24 species, more than tripling its known diversity, and increasing the total number of described Nannaria species to 78. The genus now has the greatest number of species in the family Xystodesmidae. Museum holdings of Nannaria were catalogued, and a total of 1,835 records used to produce a distribution map of the species group. Live photographs, illustrations of diagnostic characters, ecological notes, and conservation statuses are given. The wilsoni species group is restricted to the Appalachian region, unlike the widely-distributed minor species group (known throughout eastern North America), and has a distinct gap in its distribution in northeastern Tennessee and adjacent northwestern North Carolina. The wilsoni species group seems to be adapted to mesic microhabitats in middle to high elevation forests in eastern North America. New species are expected to be discovered in the southern Appalachian Mountains.

“…Members of the tribes Strongylomorphini: Brasilodesmus paulistus paulistus (Brӧlemann, 1902), Macrocoxodesmini: Macrocoxodesmus marcusi Schubart, 1947, and Arthrosolaenomeridini: Arthrosolaenomeris pantalanensis Schubart, 1943 were included as outgroups, as well as two species not assigned to any tribe (Leiodesmus sp. and Plectrogonodesmus gounellei (Brölemann, 1902)), hypothesized to be closely related to Atlantodesmus, according to Hoffman (2000) and Bouzan et al (2017Bouzan et al ( , 2019.…”

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