Supplementary description

AEDEAGUS ( Fig. 7 A–C). Ventral process of each paramere wide, distinctly narrowed apically, moderately hooked at apex; conjoint dorsal plate of parameres slightly developed, about one-fourth length of ventral process and as wide as half of the distance between outer margins of ventral processes, moderately narrowed apically, with slightly rounded apical margin.

ABDOMINAL STERNITE VIII Oŀ ŀEMALE ( Fig. 11B ). Moderately protuberant in middle of posterior margin, the middle protuberance moderately and widely triangularly emarginate at apex, forming a pair of median lobes, which are subtriangular at apices.

INTERNAL ORGAN Oŀ REPRODUCTIVE SYSTEM ( Fig. 8C ). Vagina stout, slightly thinned and extended into a slightly long duct at ventroapical portion; diverticulum and spermathecal duct arising from the end of the duct of vagina; diverticulum moderately long, spiral and abruptly narrowed apically; spermathecal duct distinctly shorter than diverticulum and thinner than basal portion of diverticulum; spermatheca composed of a spiral tube which is slightly longer than diverticulum, provided with a thin accessory gland which is slightly shorter than the spiral tube of spermatheca; median oviduct situated in middle of vagina.

Remarks

In the original publication ( Wittmer 1995), this species was only illustrated with male antennae. Here the genitalia of both sexes and abdominal sternite VIII of female are illustrated and described for the first time.
