Odontopeltis anchisteus Hoffman, 1981: 58 , figs 4–6, 10, 11.

Male holotype, from Minas Gerais, Brazil, A. Fry col., deposited at BMNH 1873.30, examined.

Additional material examined: BRAZIL: Minas Gerais: Juiz de Fora, (21°45′50′′S, 43°21′00′′W), 1♂, 10.ix.2009 ( IBSP 2874) ; Santa Fé de Minas, (16°41′24′′S, 45°24′50′′W), 1♂, Koch col. ( BMNH).

Diagnosis: Males differ from all other species of the genus by the absence of a median process on the solenomere ( Fig. 63 , arrow); the presence of a single rounded projection on process A in ventral view ( Fig. 63 ) and an apical fold in mesal view ( Fig. 62 , arrow).

Redescription: Male (holotype, BMNH 1873.30): Head red. Body reddish. Paranota tip yellow. Legs brown. Telson yellow. Paranotal teeth formula: 0-0-0-0-2-2-2- 4-5-4-6-4-3-7-4-3-3-1-1. Total length: 90. Collum 4.5 long, 13.9 wide. Antennomere length: 2.2, 2.4, 2.5, 2.3, 2.1. Genital papilla 0.4 high, 0.68 wide. Genital opening 2.0 long, 3.8 wide. Telson damaged. Gonopods: coxae with spiniform process. Prefemoral region three times longer than femoral region. Macrobristles short and in an inclined line, distance between them equal to their length. Process B projecting dorsally in mesal and ectal view, distal half slightly curved ( Fig. 64 ). Process A with a fold ( Figs 62, 64 ), visible in mesal and ectal view. Solenomere without median projection ( Fig. 63 , arrow) and a relatively long tapering tip.

Female: Unknown.

Distribution: Minas Gerais, Brazil.
