FIGURES 65–67, 86

Polydesmus (Odontotropis) clarazianus Humbert & deSaussure, 1869: 152 .

Female holotype from La Plata, Argentina, deposited in MHNG, examined; deSaussure & Humbert, 1872 (description of male).

Odontotropis clarazianus: – Attems, 1898: 408.

Storthotropis clarazianus: – Attems, 1938: 200 (comb. nov.), Schubart, 1954: 141.

Odontopeltis clarazianus: – Hoffman, 1981a: 57, figs 1–3, 7, 9 (comb. nov.).

Note: this species was described based on a female (Humbert & deSaussure, 1869) from La Plata, Argentina. DeSaussure & Humbert (1872) mentioned a male, but neither designated this male as a type nor presented a drawing. Brölemann (1900) published two drawings of a male under the name Odontopeltis clarazianus based on specimens collected by Emílio Goeldi in Serra dos Órgãos, Rio de Janeiro (specimen lost, MNHN, J-.J. Geoffroy, unpubl. data). Schubart (1949: 20, figs 1, 2) presented a drawing of a male identified by him as Odontopeltis clarazianus from Matipó, Minas Gerais, which he considered to be conspecific with the specimens illustrated by Brölemann (1900). However, Hoffman (1981a) examined the female holotype of Odontopeltis clarazianus from La Plata and concluded that the male discussed by deSaussure & Humbert (1872) is conspecific with the female type specimen, but not conspecific with the males described by Brölemann (1900) and described and figured by Schubart (1949). Based on similarities of the body between the female type specimen and male specimens, Hoffman selected a new male specimen as conspecific with the Odontopeltis clarazianus female. Therefore, the male specimens described by Brölemann (1900) and Schubart (1949) are neither conspecific with Odontopeltis clarazianus nor with any other described species of Odontopeltis . They belong to a heretofore undescribed species, described below as a new species: Odontopeltis tiradentes .

Additional material examined: BRAZIL: Rio de Janeiro: Trajano de Morais, Povoado das Almas, (22°03′46′′S, 42°03′57′′W), 1♂, 02.i.2010, P. D. P. Pinheiro col. (IBSP) . ARGENTINA: Departamento de Buenos Aires: La Plata, 1♂ (BMNH) (designated by Hoffman, 1981a: 57) .

Diagnosis: Males of Odontopeltis clarazianus differ from all other species of the genus by the presence of three apical teeth-like projections on process A (Fig. 66).

Redescription: Male (MHNG): Head and body reddish. Paranotal tips yellow. Legs brown. Telson yellow. Paranotal teeth formula: 0-0-0-0-3-5-4-7-5-6-6-3-3-4- 4-3-3-1-1. Total length 98. Collum 5.0 long, 14.0 wide. Antennae damaged. Genital papilla 0.9 high, 0.66 wide. Genital opening 1.0 long, 3.25 wide. Telson 2.5. Gonopods: coxae with distinct spiniform process. Macrobristles in an inclined line with the distance between them equal to their length. Prefemoral region 2.5 × longer than femoral region. Process B is slightly bent in clockwise direction when observed in ventral and mesal view (Figs 65, 66). Process A subrectangular, with three apical teeth-like processes (Fig. 66). Solenomere with a small median projection.

Female (holotype, MHNG): Body colour as in male. Paranotal teeth formula: 0-0-0-0-3-3-2-3-2-3-3-2-2-3- 4-2-2-1-1. Total length 96. Collum 4.7 long, 13.1 wide. Antennae damaged. Telson 2.1. Genitalia as in Odontopeltis giganteus (Figs 71–73).

Distribution: Rio de Janeiro, Brazil, and La Plata, Argentina.
