Zhong and Yang ( Fig. 22–28 ) Adult. Length of forewing 5.6–6.1 mm (N = 2). Head brown with dark yellowish antennae, pronotum dark yellow, meso- and metanota light brown, forewings light brown. Male genitalia. Posterior margin of sternum IX with mesal trapezoidal excision and small median protrusion in ventral view. Terga IX + X short, sub-trapezoidal, 1/3rd as long as width in dorsal view. Preanal appendage sub-rectangular, narrowed at base in lateral view, 2 times as long as height of distal margin. Dorsobasal process of preanal appendage enlarged basally, recurved caudad at 1/3 distance from base, with recurved portion evenly turned upward in lateral view. Inferior appendage gradually narrowed at distal 1/3rd, with apex highly sclerotized and extending beyond tips of preanal appendage; ventromesal lobe of inferior appendage well developed, forming subapical process in lateral and ventral views; in ventral view, apex of inferior appendage acute, strongly curved mesad; apex of subapical ventromesal lobe of inferior appendage slightly narrowed before blunt apex. Subphallic sclerite trough-like in caudal view ( Fig. 27 ), apex deeply excised in “V” shape and with mesal oval excision in ventral view. Phallus simple tube, about 4 times as long as average width. Holotype : male, Zhejiang Province , Mt. Tian-mu. 30.4°N , 119.5°E , Xian-ren-ding, alt. 1500 m , 20 July 1998 , Coll. ZHAO Ming-Shui. Paratype : 1 male , Zhejiang Province , Mt. Tian-mu, 30.4°N , 119.5°E , San-muping, alt. 780 m , 21 July 1999 , Coll. ZHAO Ming-Shui. Diagnosis. This new species is very similar to Polyplectropus rostriformis Zhong et al. 2006 from Anhui , in the general shape of the male genitalia. It differs from it in that: 1) apicolateral margin of each inferior appendage is broadly rounded (the outer apical angle is in right angle in P. rostriformis ); 2) the dorsobasal process of each preanal appendage is arc-shaped with apex straight (sinuate in P. rostriformis with hooked apex); and 3) the apex of the subphallic sclerite is deeply excised in a “V” shape with a mesal oval excision (deeply excised in a “V” shape with a mesal “V” shape excision in P. rostriformis ). Etymology. The species name derives from “Tian-mu-shan,” the type locality of this new species. Distribution. China ( Zhejiang ).
