Supplementary description
Male
AEDEAGUS (
Fig. 5A‒C
). Strongly swollen laterally in basal part, contracted in diameter apically; basal piece nearly as long as dorsal plate of each paramere, with a large, bifurcate conjoint middle nodule at base of ventral side; ventral processes of parameres nearly parallel to one another, distinctly thickened apically, bent dorsally in lateral view; dorsal plate slightly longer than ventral process, abruptly narrowed in middle and wide-triangularly protuberant at apical part, near to each other at basal part, apex acute and folded ventrally; apical parts of laterophyses depressed and separate from each other, apex acute and bent dorsally, reaching middle emargination between dorsal plates.
Female
ABDOMINAL STERNITE VIII (
Fig. 8F
). Moderately narrowed posteriorly, posterior margin deeply and triangularly emarginate in middle and feebly emarginate on both sides; behind notch with membrane, narrowly bilobed at apex and present with longitudinal sclerite at center.
INTERNAL ORGAN OF REPRODUCTIVE SYSTEM (
Fig. 7B
). Vagina stout, with median oviduct situated at ventroapical part, diverticulum and spermathecal duct arising from apex; diverticulum extremely long, about 0.33 times body length, evenly thinned apically, slender tube-shaped and spiral; spermathecal duct much shorter than diverticulum; spermatheca slender tube-shaped and spiral, obviously thinner than spermathecal duct and nearly as long as diverticulum, with basal part extended into short tube, where accessory gland opening. Accessory gland thin and nearly as long as spermatheca.
