One arm of gonocoxite, expanded at the base, curved, with mediolateral bristles and two setulae apically. Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare, curved and subtriangular. Presence of one pair of projections in the aedeagal complex convergents that join apically. Aedeagus bifid truncated apically ( Fig. 44F ). Ejaculatory apodeme short, the same length as gonostylus. Epandrium subquadrangular, with rounded apex. Cercus digitiform with long hairs in lateral view ( Fig. 44D ) Hypoproct with apical micropilosity ( Fig. 44E ).
