Strains A 1 (Matão, São Paulo , Brazil ): 32 males dissected; and A2 (Nova Granada, São Paulo , Brazil ): 30 males dissected . Male terminalia. The median gonocoxites of the hypandrium are square and they present a hypandrial bristle on each side ( Fig. 4A, C ). The aedeagal apex displays a punctiform dorsal protuberance, called aedeagal apical crest ( Fig. 4B, C ); and this structure as well as the aedeagal apex are covered by scales ( Fig. 4B ). The aedeagal sheath also differs from the species mentioned above, because it has several serrated and strongly chitinized crests, arranged longitudinally, dorsally, and laterally ( Fig. 4B, D ). The ventral postgonites extend along the ventral region of the aedeagus, being parallel in the initial portion and divergent at the end ( Fig. 4C, D ). The aedeagal ventral processes are thin and arranged parallel to each other ( Fig. 4D ). The pregonites are short and each pregonite displays two bristles ( Fig. 4D ).
