Diagnosis.
Apex of Sc unsclerotized; M2 with base unsclerotized; hypandrium involving the aedeagus, with a subspherical dorsal projection; arm of gonocoxite elongated coated laterally by bristles and apically by two setae; one pair of projections in the aedeagal complex; involving the aedeagus, curve-shaped; ejaculatory apodeme short, 1.25 times the length of gonostylus; cercus with apical rod-like bristles.
Description. Male.
Head subcircular in frontal view. Antenna with 13 flagellomeres; scape and pedicel subspherical; flagellomeres pyriform and eccentric (
Fig. 29A
); ascoids 1.3 times as long as the length of flagellomere; 13th flagellomere subcylindrical with terminal apiculus separated by a suture (
