• Symploce torchaceus Feng & Woo, 1999: 51.

Description

Length, male,pronotum: length × width: 3.2 × 3.8mm, tegmen: 15mm, overall length: 18mm. Body brown (Fig. 1). Head brown with a dark brown band on disc, which is wide and short. Face brown with a dark brown band. Maxillary palpomus brown and apex dark brown (Fig. 2). Pronotum pale brown with a pair of V-shaped rufous maculae in centre (Figs 1, 11). Tergum (except T1) with a dark brown spot on each side, and a dark brown stripe on disk. Vertex with interocular width slightly less than ocellus width, distinctly narrower than distance between antennal sockets. Fourth and fifth maxillary palpomus of same length, both distinctly shorter than third (Fig. 2). Pronotum elliptical and width longer than length, with anterior margin nearly truncate and hind margin slightly produced in the middle (Fig. 11). Tegmen and hind wing well developed, entirely covering abdomen (Fig. 1). Tegmen narrow and long; radius vein with apical posterior branch, which terminates at the apical margin, and with 2 small branches, one of them branched; median vein with 2 branches (Fig. 12). Radius vein of hind wing branched beyond the middle and the branches bifurcated again near apex, median vein slightly curved and simple; cubitus slightly curved with 3 complete and 3-4 incomplete branches, triangular apical area reduced and small (Fig. 13). Anteroventral margin of front femur type A3, pulvilli present on 4 proximal tarsomeres, tarsal claws symmetrical and unspecialized, and arolia present. The 1st abdominal tergum (T1) unmodified, T7 specialized with some setae on disc; lateral plates of T9 similar with hind margin rounded and unspecialized (Fig. 14).
Male genitalia. Supra-anal plate (Fig. 15) in ventral view symmetrical and nearly trapeziform, hind margin nearly straight, left side with 3 small spines and right side with 2 small spines. Right and left paraprocts (Fig. 15) obviously asymmetrical, left one dendritic and apices tapering, right one with apex scattered with many fine spines and 1 branch near base, which resembles an antler. Subgenital plate (Fig. 16) weakly asymmetrical and hind margin slightly produced in the middle, left side concave at apical half and right side curved; two styli dissimilar and lying at apex, left style large which is similar to one torch directed laterad, and with 3 small teeth at outer margin near base, right style smaller and with 3 acute spines at apex. Hook of left phallomere with sclerotized portion very small, on left side, slender and with V-shaped incision (Fig. 17). Median phallomere (Fig. 18) long and lanciform with apex tapering, right phallomere (Fig. 19) skilletlike with a twist of sclerite.
