Neocarpia trispina sp. nov.

( Figs 65‒67 )

Description. Body length: male 4.9‒5.9 mm (n = 25), female 5.3‒6.4 mm (n = 45).

Coloration. General color yellowish brown ( Fig. 65A–E ). Eyes brown, ocelli light yellow. Vertex generally yellowish brown, carinae brown to dark brown (except median carina yellowish white). Face generally yellowish brown, carinae brown to dark brown; rostrum yellowish brown. Pronotum and mesonotum yellowish brown. Forewing semi-translucent, basal half yellowish brown and distal half darker, with blackish brown spots on end of longitudinal veins. Hind tibiae and abdominal sternites yellowish brown.

Head and thorax. Vertex ( Fig. 65C , 66A ) broad, 2.2 times wider than long; anterior margin slightly produced in the middle, posterior margin archedly recessed. Frons ( Fig. 65D , 66B ) widest at the level of antennae, 1.2 times as long as wide; frontoclypeal suture nearly concave into an arch; middle carina complete; lateral carinae distinct and elevated. Pronotum ( Fig. 65C , 66A ) 2.3 times longer than vertex; median carina indistinct, posterior margin nearly at right angle. Mesonotum 1.6 times longer than pronotum and vertex combined. Forewing ( Fig. 66C ) 2.7 times longer than wide, with 10 apical and 6 subapical cells; fork Sc+RP basad of fork CuA 1 +CuA 2, first crossvein r-m slightly distad of fork MP; RP two branches, MP with five terminals: MP 11, MP 12, MP 2, MP 3, and MP 4, fork MP 1 +MP 2 basad of fork MP 3 +MP 4. Metatibiotarsal formula: 6/5/8, second segment of hind tarsus with three platellae.

Male genitalia. Pygofer ( Fig. 66D, E ) symmetrical, dorsal margin concave and U-shaped ventrally, slightly widened towards apex; in lateral view, lateral lobes triangularly extended caudally, medioventral process round ventrally. Anal segment ( Fig. 66D, F ), dorsal margin almost straight, ventral margin with two triangular processes; and 1.9 times longer than wide in dorsal view; anal style strap-shaped, not beyond anal segment. Gonostyli ( Fig. 66D, E, G ) symmetrical in ventral view; in inner lateral view, apical margin of gonostyli with a small blunt process, dorsal margin bending inwards in the middle. Aedeagus ( Fig. 66H–K ) in total with seven processes. In right side, apex of periandrium with two straight spinose processes, the upper one dorsocephalically directed and the other one slightly shorter and apex cephalically directed; base of periandrium with a transverse triangular laminal process, right side directed; left side of periandrium with a straight spinose process at apex, dorsocephalically directed. Endosoma (=flagellum) moderately sclerotised, generally dorsally curved; right side each with a straight spinose process in the middle and near apex, dorsocephalically directed; apex with a spinose process, ventrocephalically directed.

Female genitalia. Tergite IX ( Fig. 67A, C ) moderately sclerotised, with length almost equal to width in caudal view. Anal tube ( Fig. 67A, B ) short, nearly rectangular, slightly longer than wide in dorsal view; anal styles relatively short and small. Gonapophysis VIII ( Fig. 67D ) elongate, and slightly curved upwards. Gonapophysis IX ( Fig. 67E ) with one middle tooth, at a distance ratio, between middle tooth to apex and length of denticulate portion, of 1.6. Gonoplac ( Fig. 67F ) rod-like, 4.3 times longer than wide. Posterior vagina ( Fig. 67G, H ) elongate, in ventral view, with a large transverse oval sclerite and five longitudinal sclerites; in dorsal view, with two oval sclerites.

Type material. Holotype: ♂, CHINA: Mohan Town (21°14’N, 101°42’E), Mengla County, Yunnan Province, 22 June 2016, leg. Ying-Jian Wang; paratypes: 21♂♂ 42♀♀, same collection area as holotype, 22–23 June 2016, leg. Liang-Jing Yang, Ying-Jian Wang and Qiang Luo; 1♂, same collection area as holotype, 15 August 2013, leg. Mei-Na Guo; 2♂♂ 3♀♀, Mei Village (24°8’N, 110°6’E), Jinxiu Town , Jinxiu County , Guangxi Zhuang Autonomous Region , 30 April 2011, leg. Xiao-Fei Yu, Rong Huang and Xin-Feng Zhang.

Distribution. China (Guangxi, Yunnan).

Host plant. Unknown.

Remarks. This species is similar to N. bidentata Zhang & Chen, 2013 , but differs in: (1) right side of periandrium with two spinose processes at apex and a transverse triangular laminal process at base (the latter with one spinose process at apex and without laminal process at base); (2) neither dorsal nor ventral margins of periandrium with process (in N. bidentata , dorsal margin of periandrium with a shovel-shaped process and ventral margin with a small triangular spine); (3) endosoma with three spinose processes (the latter with one spinose process).

Etymology. The specific name is derived from the Latin prefix “ tri- ” and noun “ spina ”, referring to endosoma of aedeagus with three spinose processes.
