Figs 36−42, 55

Type material. Holotype male from Floresta Nacional do

Tapajós (03°31’01”S; 55°04’23”W), Belterra, Pará, Brazil, X/2011, A.D. Brescovit et al. leg. ( IBSP 218933 ) .

Diagnosis. Bumba tapajos sp. nov. resembles B. humile due to the presence of a denticulate row (DR) on middle region of PI ( Figs 36−40) but this is more evident and tibial apophysis with a subapical spine on retrolateral branch ( Figs 41−42) absent in B. humile .
