Diagnosis. The male of M. fonsecai is similar to those of the species within the vicana species-group, especially those of M. vicana , M. silvae and M. pereirae for not having mastidia, and by having a bump on the retrolateral, proximal portion of palpal tibia ( Figs 34, 38, 40 ), and the prolateral portion of tegulum (embolus base) strongly asymmetrical proximally when compared to the retrolateral portion. It can be distinguished from those of M. vicana and M. pereirae for having a bifid embolus tip ( Figs 40 , 48 ), and from M. silvae for having a bifid, short RvTA ( Figs 41 , 54 ). The male also resembles those of M. aragog for having the bifid embolus tip (developed membranous portion), but can be distinguished for having joint prolateral cheliceral teeth, no bump on fang, no mastidia, besides the shape of tibia and palpal bulb.
