Synonymy. Recently we received larger number of couples of the Bumba from Ilha de Maracá , the type locality of B. cabocla . We observed males measuring only 25 mm until 45 mm, and females at 50 mm. Also the number of labial cuspules present variation from 0-20. Comparing details of the tip of embolus and tibial apophysis of the male palp bulb and female receptacles of the spermathecae of these specimens with those presented by Bertani and Carla-da-Silva (2003, figs 1–4; 6–9), these are quiet indistinct. The female presented by Pérez-Miles (2000, fig. 7) it is rather an immature specimen, as shown in fig. 8F. So, we proposed here the synonymy of these species.

Diagnosis. Bumba horrida differs from Bumba humile by the having fewer labial cuspules, between 0–20, male palpal bulb with PS expanded near the apex, presenting a subapical lobe ( Figs 48–49, 51−52) and tibial apophysis with retrolateral side of the retrolateral branch with one strong spine ( Fig. 50). Female spermathecae with two receptacles originating from a large base and enlarged neck ( Figs 53−54).
