M a l e: Sternite 7 broadly and shallowly emarginate at posterior margin. Sternite 8 (fig. 25). Sternite 9 acute apicomedially, no fields of ha present. SpP tubular, about 1.5x as long as the median lobe, with a long tubular connection with the vs, which is about as long as the apex of the median lobe. Aedeagus (fig. 49), parameres shorter than median lobe, with a moderately long apical and one shorter subapical seta.
