Diagnosis. Bumba species have been characterized by the following character combination: type IV urticating setae present, retrolateral process on male palpal tibia, palpal bulb resting in a ventral distal excavation of palpal tibia, metatarsus I passes between the two branches of tibial apophysis when flexed, presence of spiniform setae on prolateral and retrolateral sides of maxillae and coxae I-IV (Pérez-Miles 2000, Bertani and Carla-da-Silva 2003, Pérez-Miles et al. 2014). Here we suggest the inclusion of the row of teeth (denticulate row) in the median region of the inferior prolateral keel (Figs 2, 27, 36). This structure is present on all male palps, which may range from a residual tooth (Fig. 34) to a ridge of up to five teeth (Figs 38−40). Both the denticulate row and the retrolateral process on male palpal tibia could be considered as putative synapomorphies for this genus.
