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 ) .

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).
