Aedeagus: slender; (1) apical portion with fine denticulation, extended only on the apical portion, lateral margin straight; (2) penis valve widely dilated and with a slight central entrance (about 1/4 of the total length of apical portion); (3) median expansion developed, rounded apex; (4) lateral apodeme directed forward and shorter than the ventral process, (5) ventral process rounded and slightly dilated in apex; (6) inferior portion of aedeagus curved, in lateral view. Digitus: damaged (not seen). Cuspis: slender; (1) apex pointed and
