Descriptive notes

Body length (both sexes): 7.2‒10.6 mm; width: 1.5‒2.5 mm.

Male ( Fig. 1F View Fig )

AEDEAGUS ( Fig. 6A‒C View Fig ). Strongly swollen dorsally at basal part, moderately reduced apically in diameter; basal piece slightly shorter than dorsal plate of each paramere, with a large, bifurcate conjoined middle nodule at base of ventral side; ventral processes of parameres nearly parallel to each other, moderately long and slightly narrowed apically, bent dorsally in lateral view; dorsal plate obviously longer than ventral process, evenly narrowed apically, apex rounded, outer margins folded ventrally; apical parts of laterophyses compressed and next to each other, apex acute and directed laterally, distinctly exceeding emargination between dorsal plates.

Female ABDOMINAL STERNITE VIII ( Fig. 3E View Fig ). Obliquely narrowed posteriorly and slightly sinuate, lateroapical angles obtusely triangular, posterior margin deeply and triangularly emarginate in middle and widely

truncate on both sides.

INTERNAL ORGAN OF REPRODUCTIVE SYSTEM ( Fig. 8A View Fig ). Vagina elongate, with median oviduct situated at ventroapical part, vagina abruptly narrowed in apical part and extended into a long duct which diverticulum and spermathecal duct are arising from; diverticulum relatively short, about 0.29 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 much 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, nearly as long as spermatheca.

Distribution

China (Shaanxi, Gansu, Henan, Hubei, Sichuan, Xizang). New records for Shaanxi, Gansu, Henan, Hubei, Xizang.

Remarks

The female reproductive system and dorsal and lateral views of the aedeagus for this species are described and illustrated for the first time.
