ODONTOPELTIS TIRADENTES SP. NOV.

FIGURES 74–76 , 87

Storthotropis clarazianus: Schubart, 1949: 20 , figs 1, 2 (male description, from MZSP, misidentification); Brölemann, 1900: 65 (male = Odontopeltis tiradentes ).

Type material: Male holotype from Viçosa, (20°45′ 14′′S, 42°52′55′′W), Minas Gerais, Brazil, 1947, deposited in MZSP, catalog number 909; labelled as ‘ O. clarazianus ? ’, most likely one of the specimens Schubart examined .

Note: this species is based on a male identified as Odontopeltis clarazianus by Schubart (1949), who based his identification on gonopod drawings by Brölemann (1900). Hoffman (1981a) noted that Brölemann’s and Schubart’s specimens are not conspecific with the female type specimen of Odontopeltis clarazianus . The original specimen described by Brölemann is lost, and so is the body of Schubart’s specimen. However, the gonopods of Schubart’s specimen, mounted on microscope slides, are available (MZSP 909), and were compared to another specimen in MZSP labelled Odontopeltis clarazianus , now holotype of Odontopeltis tiradentes . The diagnosis and description of Odontopeltis tiradentes are based on these two specimens.

Additional material examined: BRAZIL: Minas Gerais: Matipó, Fazenda Floresta, (20°16′S, 42°21′W), only male gonopods from Schubart, viii.1919, P. da Fonseca coll. (MZSP 909).

Etymology: The species epithet is a noun in apposition, after the nickname Tiradentes of Joaquim José da Silva Xavier, a Brazilian national hero known for leading the Inconfidência Mineira in 1789.

Diagnosis: Males of Odontopeltis tiradentes are similar to Odontopeltis giganteus in the slightly curved tip of process B in mesal view ( Fig. 74 ). Odontopeltis tiradentes differ from Odontopeltis giganteus by the wider shape of process A ( Fig. 75 , ventral view), and by the absence of a hump on the solenomere (in mesal view, Fig. 74 ). Odontopeltis tiradentes differs from all other species of the genus by a constriction in the basis of the solenomere ( Fig. 75 , ventral view, arrow).

Description: Male (holotype): Head and body red. Tip of paranota and telson yellow. Legs orange. Paranotal teeth formula: 0-0-0-0-2-4-3-4-3-3-5-3-3-4-3-3-3-1-1. Total length 90. Collum 5 long, 14 wide. Antennae: 2.4, 2.0, 2.0, 2.1, 2.1. Genital opening 3.9 wide, 2.4 long. Telson 2.0. Gonopod coxa with a spiniform process. Prefemoral region 3 × longer than femoral region. Macrobristles on an inclined line, close together, with the distance between them less than half the length of the bristle itself. Process B with the tip slightly curved ectally. Process A elongated, without projections. Solenomere with a basal constriction and a well-developed median projection.

Female: Unknown.

Distribution: Minas Gerais, Brazil.
