Descriptive notes

Body length (both sexes): 7.5‒10.0 mm; width: 1.4‒2.0 mm.

Female

ABDOMINAL STERNITE VIII ( Fig. 3F ). Moderately narrowed posteriorly, lateroapical angles widely triangular, posterior margin shallowly and roundly emarginate in middle and feebly emarginate on both sides.

INTERNAL ORGAN OF REPRODUCTIVE SYSTEM ( Fig. 8B ). Vagina stout, with median oviduct situated at ventroapical part, vagina abruptly narrowed in apical part and extended into a short duct which diverticulum and spermathecal duct are arising from; diverticulum relatively short, about 0.32 times adult body length, evenly thinned apically, slender tube-shaped and spiral; spermathecal duct slightly long but much shorter than diverticulum; spermatheca slender tube-shaped and spiral, obviously thinner than spermathecal duct and slightly longer than diverticulum, with basal part extended into a short tube, at opening of accessory gland. Accessory gland thin in basal part and the remainder moderately thin, slightly shorter than spermatheca.

Distribution

China (Sichuan, Yunnan).

Remarks

The species was originally described from the male type, and subsequently Švihla (2011) described the female and illustrated abdominal sternite VIII. In the present study, the female reproductive system is described and illustrated for the first time.
