Stenopsyche jinxiuensis sp. nov.

(Figs. 6a–f)

Adult (in alcohol). Length of forewing 22.0 mm (n=1). Forewing narrow and long, dark brown, with many light speckles. Hind wing triangular, semi-transparent. Wing venation (Figs. 6a–b) typical of genus, but in forewing crossveins r-m and m-cu transparent, distance between m-cu and cu twice length of cu.

Male genitalia. Abdominal segment IX annular, in lateral view shortest at insertion of preanal appendage, ventral 1/3rd of pleuron IX strongly produced anterad and posterad with ventral margin at least 4 times as long as dorsal margin; apicolateral angle long and acute, about 1/4th as long as preanal appendage; in ventral view anterior margin of sternum IX with semicircular indentation. Preanal appendage long, setose. Segment X is tonguelike, membranous with base broad and apex elongate, about 2/3rds as long as preanal appendage, apex incised in dorsal view. Intermediate appendage in dorsal view as long as segment X, curved inward at angle of 90° at 1/4th distance from base, and subapex narrowed abruptly, apex acute; in lateral view sinuate with acute apex. Superior arm long, about 2/3rds as long as preanal appendage, in dorsal view arched laterad, apex thick; in lateral view sinuate. Inferior appendage highly depressed in lateral view, sub-rectangular in ventral view, about 4 times as long as wide. Phallus with large 5 spines, endothecal armature bearing many fine spines.

Holotype male: CHINA, Guang-xi Province, Jin-xiu County, Jin-zhong Road, 24.13°N, 110.189°E, alt. 1100 m, 11 May 1999, by black light trap, collected by Han Hong-xiang.

Diagnosis. The new species belongs to the second subgroup, but differs from other members in that (1) segment X in dorsal view has its basal half broad and its distal half narrow (with lateral margins parallel to each other in S. stoetzneri; sagittate in S. uniformis; very short in S. longispina; triangular in S. denticulata; rectangular in S. acanthoclada sp. nov.); (2) the intermediate appendage is elongate, curved inward at an angle of 90° at 1/4th distance from the base (arched in S. stoetzneri and S. uniformis; curved inward at an angle of 120° at 1/3rd distance from base in S. longispina; short and thick, curved inward at an angle of 120° at half the distance from the base in S. denticulata and curved inward at an angle of 100° at half the distance from the base in S. acanthoclada sp. nov.).

Etymology. This species is named for the type locality, Jin-xiu County in Guang-xi Province, China.

Distribution. China (Guang-xi).
