Type material.

Holotype: ♂, China: Guizhou, Anlong, Xianheping (24°58'N, 105°36'E), 28 Aug. 2012, W.-B. Zheng.

Diagnosis.

This species can be distinguished from other Tetricodes species by the anal tube (Fig. 37) irregular circular, with sunken trilateral at apical margin in dorsal view; phallobase with dorsal lobe with irregular collar-shaped and long lobe-shaped process (Fig. 38a); lateral lobe with a stout lobe-like prominence and hook-shaped prominence in apical part in ventral view (Fig. 39c). Aedeagus with big sheet-like processes in lateral view (Fig. 38e).

Description.

Body length: male 5.8 mm, Forewing: male 4.9 mm.

Coloration. As in T. parvispinus Chang & Chen, sp. n., but clypeus black with yellow mark at base, rostrum brown and pronotum (Fig. 31) with four pale vurrucae between median carina and lateral carina.

Head and thorax. Head (Fig. 31) including eyes narrower than pronotum (0.67: 1.00). Vertex (Fig. 31) shorter in middle than the wide at base (0.63: 1.00). Frons (Fig. 33) longer in middle than the widest breath (1.30: 1.00). Clypeus triangular, with obscure median carina and rostrum surpassing mesotrochanters. Pronotum (Fig. 31) with median carina. Mesonotum (Fig. 31) with lateral carinae. Hind tibiae each with 4 spines, one of small spines near base, spinal formula of hind leg 8 –10– 2. Forewings (Fig. 34) elongate, 2.5 times as long as maximum breadth, ScP and Rp convergent near base, MP three branched, MP1+2 bifurcates apically, CuA simple, not forked; CuP present, Pcu and A1 uniting in basal 2/3 of clavus. Hindwings (Fig. 35) with two big lobes, anal lobe reduced.

Male genitalia. Anal tube (Fig. 37) irregular circular, with pitted triangular in apical margin in dorsal view, the widest breath in apical 1/2. Anal style (Fig. 37) long, located in the middle of anal tube. Pygofer (Fig. 36) narrow and curved in lateral view, irregular subquadrate. Genital styles (Fig. 36) short, with obscure triangular prominence near dorsal margin before capitulum; capitulum of genital styles relatively short, subtrapezoidal on short neck. Phallobase with dorsal lobe with irregularly collar- shaped process near apical part in lateral view (Fig. 38a), with long lobe-shaped process in dorsal margin in base (Fig. 38b); lateral lobe splitting into two branches, with stout lobe-like prominence and hook-shaped prominence in apical part in ventral view (Figs 38c, 39c); ventral lobe short, in ventral view ventral lobe with three lobe near apical part, the apical margin acute (Figs 38d, 39d). Aedeagus with pair of big sheet processes in apical 1/3 in lateral view (Figs 38e, 39e).
