Zhong and Yang ( Figs. 1–7 ) Adult. Length of forewing 5.4–6.0 mm (N = 2). Head light brown with yellowish antennae, pronotum dark yellow, meso-, metanota and forewings light brown. Male genitalia. Posterior margin of sternum IX with semicircular excision in ventral view. Terga IX + X short, sub-trapezoid in dorsal view. Preanal appendage approximately 4 times as long as apical width, narrowed at 1/3 distance from rounded apex in lateral view. Dorsobasal process of preanal appendage needlelike and recurved caudad at 1/4 distance from base in lateral view. Basal half of inferior appendage broad and apical half slender in lateral view, with distal end extending beyond distal end of preanal appendage; in ventral view, inferior appendages elbowed, with apical half gradually narrowed and apex slightly concave mesally; ventromesal lobe located at basal half of inferior appendage and setose, with apical “U” excision in lateral view; in ventral view, with apical margin toothed irregularly. Subphallic sclerite trough-like, with lateral walls strongly erect and bottom expanded horizontally in caudal view; in ventral view, its apex with mesal “U” excision. Phallus simple tube, about 4 times as long as average width. Holotype : male, Guizhou Province , Chi-shui County, 28.34°N , 105.42°E , Hu-shi-zhen, Nan-zhu-linchang, Jin-sha-gou, Gong-ye-gan-gou, 9 November 1995 , Coll. WANG Bei-Xin, SUN Chang-Hai. Paratype : 1 male , same data as holotype . Diagnosis. This new species belongs to the P. anakgugur Group and is very similar to Polyplectropus anakgugur Malicky 1995 , from Malaysia . It differs in that 1) the basal half of inferior appendage is broad and the apical half slender in lateral view (equally wide in P. anakgugur ); 2) terga IX+X has no process (with a pair of horn-shaped processes in P. anakgugur ); 3) the apex of the subphallic sclerite has a mesal “U” excision (a broad excision, with the mesal portion strongly protruded and with a small notch at its center in P. anakgugur ). Etymology. The species name is a Latin adjective cubitalis (= cubital) to indicate the shape of inferior appendages in ventral view. Distribution. China ( Guizhou ).
