Male genitalia. Eighth sternite (Figs 521-522) apically with several pseudo-pores, entirely fused, strongly sclerotized; apex of eighth sternite laterally with two tufts of several short setae; eighth tergite and eighth sternite fused laterally (Fig. 523). Ninth tergite (Figs 524-525) typical for the subfamily; anterior margin of tenth tergite inwardly arcuate; spiculum gastrale (Fig. 524) gradually dilated on apical half; apical end strongly sclerotized; basal end abruptly dilated, triangular, basal end outwardly arcuate. Aedeagus (Figs 526-527) subparallel, before apex slightly dilated; parameres fused along their basal half (roughly); basal piece of aedeagus short, ratio of its length: length of parameres 1: 6; aedeagus almost straight, only apically slightly curved from lateral view (Fig. 527). The male terminalia of
