Neotetricodes clavatus Chen, Zhang et Chang, 2014

( Figs 5 , 52–55 )

N. clavatus Chen, Zhang & Chang, 2014: 112 : Figs A–H.

Description. Coloration. General color brown. Vertex, pronotum and mesonotum brown or black.

Head and thorax. Head including eyes narrower than pronotum (0.74: 1.00). Vertex shorter in midline than wide at base (0.45: 1.00), with median carina. Frons flat, longer in middle than the widest portion (1.00: 1.00), with median and lateral carinae. Pronotum with median carina. Tegmina elongate, 2.3 times as long as maximum width, ScP and R forked near 1/5 base, MP three or four branched, MP1+2 bifurcate near apical margin or no bifurcate, MP3+4 bifurcate at middle part, uniting near apical margin, CuA not forked, simple, CuP present, Pcu and A1 uniting in basal 2/3 of clavus. Hindwings deeply incised on apical margin into two big lobes, with a network of veins, anal lobe reduced. Hind tibiae ( Figs 10, 11 ) each with 2 or 3 spines, spinal formula of hind leg 8–10(8)–2.

Male genitalia. Anal tube in dorsal view sub-triangular, relatively short, with two lobes near apical margin. Anal style short, located in middle of anal tube. Phallobase with dorsal lobe with one clavate process in base, with a small triangular near apical part in lateral view; in ventral view ventral lobe irregularly quadrate, the apical margin blunt triangular in middline. Aedeagus with lamellar processes near middle.

Female genitalia. As in N. longispinus Chang et Chen , sp. nov., but anal tube ( Fig. 52 ) sub-rectangular, distinctly longer in middle than the widest portion (1.77: 1.00), Anterior connective lamina of gonapophyses VIII ( Fig. 54 ) with 6 teeth bearing 6 keels in lateral group. Posterior connective lamina of gonapophyses IX ( Fig. 55 ) subtriangular, long, lateral field without one triangular process; sublateral field with one triangular prominence ( Fig. 55 a) in middle between lateral field and median field; median field with a hill-shaped prominence (medial dorsal process), the apical margin smooth, without median incision ( Fig. 55 ), distal parts bent at acute angle in dorsal view ( Fig. 55 ).

Material examined. 1♂ (holotype), Dayi, Wangmo County (25°21’N, 106°06’E), Guizhou Province, 21 Aug. 2012, W.-B. Zheng; 1♂ 1♀ (paratype), same data as holotype; 3♂♂3♀♀ (paratype), Xianheping Provincial Natural Reserve(24°59’N, 105°36’E), Guizhou Province, 28 Aug. 2012, W.-B. Zheng and J.-K. Long.
