ODONTOPELTIS CONSPERSUS ( PERTY, 1833) View in CoL

Polydesmus conspersus Perty, 1833: 210 , L, fig. 8. Male holotype, from Minas Gerais, Brazil, deposited at ZSM, lost (Dr Roland Melzer). Gervais, 1836: 378; Gervais, 1837: 44; Brandt, 1839: 310; Lucas, 1840: 525; Gervais, 1847: 112.

Odontopeltis conspersus View in CoL : – Pocock, 1894: 509 (comb. nov.); Pocock, 1909: 168; Hoffman, 1981a: 56.

Neotype: Male from Betim (19°58′04′′S, 44°11′52′′W), Minas Gerais, Brazil, without date or collector data, here designated as neotype ( IBSP 2852).

Note: the proposition of the neotype is based on the original description by Perty (1833) and the description and figure by Koch (1863), who examined the remains of Perty’s specimen. Perty (1833) gives ‘mountains of Minas Gerais’ as the type locality.

Additional material examined: BRAZIL. Minas Gerais: Viçosa (20°45′14′′S, 42°52′55′′W), Campus da Escola Superior de Agricultura, 1 male, 1940 ( MZSP 906).

Diagnosis: Males of Odontopeltis conspersus differ from all other species of Odontopeltis by the rounded tip of process B (PrB), visible in mesal and ectal view ( Figs 59, 61 View Figures 59–64 ). The shape of process A (PrA) is similar to the one in Odontopeltis tiradentes , but is distinguishable by its oval shape (visible in mesal and ventral view, Figs 74, 75 View Figures 74–79 ). Odontopeltis tiradentes is distinguishable from Odontopeltis conspersus by the basal constriction of the solenomere in the former ( Fig. 75 View Figures 74–79 , arrow).

Redescription: Male (Neotype, IBSP 2852): Head red. Body pale yellow to white, with many red spots in dorsal view. Tips of paranota yellow or white. Legs and telson yellow. Paranotal teeth formula: 0-0-0-0-2- 2-3-2-3-3-2-3-3-2-3-3-3-0-0. Total length 90. Collum 5 long, 13 wide. Antennomere length: 2.2, 2.3, 2.3, 2.4,?. Genital opening 2.1 long, 3.4 wide. Telson broken. Gonopods: coxae with spiniform process, macrobristles vertically aligned, separated by less than their length. Prefemoral region three times longer than femoral region. Process B subtriangular, pointing dorsally in ectal and mesal view ( Figs 59, 61 View Figures 59–64 ). Process A oval (in ventral view, Fig. 60 View Figures 59–64 ), without projections, half as long as solenomere. Solenomere with a small median projection.

Female: Unknown.

Distribution: Minas Gerais, Brazil.
