Additional material examined: BRAZIL: Minas Gerais: São Gonçalo do Rio Abaixo, (19°49′33′′S, 43°21′43′′W), Estação Ambiental de Peti , CEMIG, 7♂, 4♀, 05−08.i.2010, J. P. P. Pena Barbosa et al. coll. [ IBSP 3617 (1♀), 3620–3621 (2♀), 3622–3625 (4♂), 3626 (1♀), 3627 (1♂), 3629 (1♂), 3693 (1♂)] .

Etymology: The species epithet is a noun in apposition, a patronym in honour of Ana Jacinta de São José, known as Dona Beja, a woman from Minas Gerais known for her beauty and curious life history.

Diagnosis: Males of Odontopeltis donabeja differ from all other species of the genus by the large and distinct median process of the solenomere, surpassing the tip of the solenomere ( Figs 78, 79 ). Males of Odontopeltis xica are similar with regard to the posteriorly curved tip of process B; however, the curvature is much more pronounced in Odontopeltis xica . In Odontopeltis donabeja process B is subtriangular in shape, whereas it is rounded in Odontopeltis xica .

Description: Male (holotype, IBSP 1668): Head and body black. Tip of paranota and telson yellow. Legs brown. Paranotal teeth formula: 0-0-0-0-2-2-3-2-3-3- 2-4-3-2-3-3-3-1-1. Total length 87. Collum 5 long, 13 wide. Antenna: 2.3, 2.2, 1.9, 2.0, 2.3. Genital opening 2.0 long, 3.5 wide. Telson 1.9. Gonopod coxa with a spiniform process. Prefemoral region 2.5 × longer than femoral region. Macrobristles on an inclined line with the distance between them less than half the length of the bristle itself. Process A with a depression ( Fig. 78 , arrow). Process B subtriangular and slightly curved to posterior.

Female (paratype, IBSP 3618): Coloration as in male. Paranotal teeth formula as in male. Total length 80. Collum 4 long, 12 wide. Antenna: 2.1, 1.7, 1.9, 2.1, 2.0.

Distribution: Minas Gerais, Brazil.
