Supplementary description

AEDEAGUS ( Fig. 13 A–C). Ventral process of each paramere wide, abruptly narrowed at apical portion and pointed at apex; conjoint dorsal plate of parameres well-developed, slightly longer than the length of ventral process and as wide as nearly half of the distance between outer margins of ventral processes, nearly parallel-sided, with apical margin deeply emarginate in middle, the deepness of the middle emargination about half length of conjoint dorsal plate; laterophyses thin, straight and pointed at apices, separated but leaning against each other and sin middle of dorsal side of conjoint dorsal plate.

ABDOMINAL STERNITE VIII Oŀ ŀEMALE ( Fig. 16A ). Distinctly protuberant in middle of posterior margin, the middle protuberance widely rounded at apex.

INTERNAL ORGAN Oŀ REPRODUCTIVE SYSTEM ( Fig. 15A ). Vagina stout, abruptly thinned and extended into a long duct at apex; diverticulum and spermathecal duct arising from the end of the duct of vagina; diverticulum very long, thin and spiral; spermathecal duct distinctly shorter and thicker than diverticulum; spermatheca composed of a spiral tube which is nearly as long as diverticulum, provided with a thin accessory gland, which is much shorter than the spiral tube of spermatheca; median oviduct situated at apex of vagina.

Remarks

In the original publication ( Wittmer 1972), this species was only illustrated with antenna of the male. Here the genitalia of both sexes and abdominal sternite VIII of female are illustrated and described for the first time.

Distribution
