Tetricodissus pandlineus sp. nov.

( Figs 1–22 )

Description. Length: male (including fore wings) (N=14): 5.5–6.2 mm; female (including fore wings) (N=11): 6.1–7.2 mm.

Coryphe brown, 1.7 times wider at base than long in midline, with yellow line in middle ( Figs 1, 2 ). Metope brown, 1.2 times broader in midline than widest part, with arc-shaped black markings from apex of disc extending to basal 4/5 and two yellow spots on the side of median carina, several unconspicuous verrucae along the arcshaped dark marking, apical angles of metope black, basal margin yellow ( Figs 5, 6 ). Postclypeus pale brown, with several oblique dark brown stripes each side, apical margin with two dark brown patches ( Figs 5, 6 ). Eyes grey. Genae brown, with an oblique yellow fascia below eyes. Pronotum brown, 1.2 times longer in midline than coryphe, yellow in midline, each side distributed with about nine verrucae on disc ( Figs 1, 2 ). Mesonotum pale brown, 2.1 times wider in anterior margin than long in midline, with two dark brown longitudinal bands on disc ( Figs 1, 2 ). Fore wings dark brown, 2.6 times longer at longest part than width, main venations reddish brown and elevated, with numerous yellow transverse veins crossed ( Figs 1, 2 ); female paler, a darker V marking more or less visible ( Fig. 2 ) and 2 darker apical patches diffused ( Fig. 2 ). Hind wings brown. Legs tawny. Metatibiotarsal formula: 8-11-2.

Male genitalia. Anal tube mushroom-like in dorsal view, longer in midline than widest part, with apical margin distinctly concave medially, epiproct short, located at basal 1/3 of anal tube ( Fig. 10 ). Gonostylus symetrical, nearly triangular in lateral view, gradually tapering to apex, caudo-ventral angle acutely rounded ( Figs 9, 12 ). Capitulum of gonostylus subtriangular ( Fig. 12 ), short and broad in caudal view ( Fig. 15 ). Pygofer broad, in lateral view anterior margin and posterior margin almost paralleled, dorsal margin slightly inclined caudad ( Fig. 9 ). Periandrium with a pair of long acute processes directed cephalad derived from apical 2/3 ventrally ( Fig. 13 ), crossed at middle in ventral view ( Fig. 11 ); dorsal periandrium lobe (dl) slightly shorter than lateral lobes, flattened ( Fig. 13 ); lateral periandrium lobes (ll) sharped, with a small apical blackish tooth ( Fig. 13 ); ventral periandrium lobe (vl) flattened, slightly shorter than lateral lobes, in ventral view with apical margin weekly convex medially ( Fig. 11 ). Aedeagus s.s. (ae) fully enclosed in periandrium, with apical part paired and digitiform ( Figs 11, 13, 14 ).

Female genitalia. Anal tube in dorsal view oval, apical margin almost straight, lateral margins convex, epiproct located near base ( Fig. 16 ). Hind margin of sternite VII shallowly concave medially, with peculiar furcated median process ( Fig. 17 ). Anterior connective lamina of gonapophysis VIII with two large and one small teeth in apical group and four keeled teeth in lateral group ( Fig. 18 ). Endogonocoxal process membranous and developed, reaching the same level with gonapophysis VIII ( Fig. 18 ). Gonapophysis IX triangular in ventral view, broaden near middle and near base ( Fig. 20 ), posterior connective lamina of gonapophysis IX fused medially. Gonospiculum bridge short and broad. Gonoplacs in dorsal view fused near base, with apical part membranous ( Fig. 21 ), nearly rounded in lateral view ( Fig. 22 ).

Type materials. Holotype: ♂, China: Menglun, N 21º 57' 0.10'', E 101º 12' 0.58'', 817 m, 18 viii 2011, Mengla County, Xishuangbanna, Yunnan Province, collected by canopy fogging, coll. Guo Zheng ( NWAFU). Paratypes: 6♂♂6♀♀, the same data as holotype ( NWAFU); 7♂♂5♀♀ (6♂♂5♀♀ in NWAFU, 1♂ 1♀ in MNHN), China: Menglun, N 21º 36' 12.1'', E 101º 34' 23.9'', 826 m, 14 vii 2012, Mengla County, Xishuangbanna, Yunnan Province, collected by canopy fogging, coll. Guo Zheng.

Etymology. The combined Latin name refers to the arc-shaped dark markings on both sides of median carina on disc of metope.
