Figs 22−28, 55 RG 1979, 14.X ..2002
Type material. Holotype male from Parque Nacional das Emas (18°6’23”S; 52°55’40”W), Mineiros, Goiás, Brazil, 28/ VII/1997, Valdujo and Nogueira leg. (IBSP 112328). Paratype female from UHE Guaporé (15°07”S; 58°58”W), Rio Guaporé, Pontes e Lacerda / Vale de São Domingos, Mato Grosso, Brazil, 14/X/2002, Equipe Resgate Fauna leg. (IBSP112231).
Diagnosis. Males of Bumba mineiros sp. nov. resemble B. rondonia sp. nov. by the palpal bulb with a long and thin embolus with weakly developed keels (Figs 22–23), with only PI visible but the tooth on PI is more evident (Fig. 27) and the embolus is shorter than that of B. rondonia sp. nov. Females could be distinguished from Bumba rondonia sp. nov. by the curved necks of the seminal receptacles (Fig. 28).
