Supplementary description

AEDEAGUS ( Fig. 3 A–C). Ventral process of each paramere wide, slightly narrowed apically, largely hooked at apex; conjoint dorsal plate of parameres moderately developed, about half length of ventral process and as wide as half of the distance between outer margins of ventral processes, moderately narrowed apically, with straight apical margin.

ABDOMINAL STERNITE VIII Oŀ ŀEMALE ( Fig. 5D ). Slightly protuberant in middle of posterior margin, the middle protuberance widely and shallowly emarginate at apex, forming a pair of median lobes, which are slightly arcuate at apices.

INTERNAL ORGAN Oŀ REPRODUCTIVE SYSTEM ( Fig. 2D ). Vagina stout, abruptly 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 distinctly thinned apically; spermathecal duct distinctly shorter than diverticulum and narrower than basal portion of diverticulum; spermatheca composed of a spiral tube which is nearly as long as 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

The aedeagus of this species was illustrated in ventral and dorsal views by Wittmer (1982), here it is illustrated again and described in detail. Also, the characters of abdominal sternite VIII and genitalia of female are provided for the first time.

Distribution

Taiwan.
