Neocarpia brevispina sp. nov.

( Figs 54‒55 )

Description. Body length: male 5.1‒5.3 mm (n = 3).

Coloration. General color brown ( Fig. 54A–E ). Eyes dark brown, ocelli yellow. Vertex and face generally brown, carinae paler. Rostrum brown with dark brownish apex. Pronotum and mesonotum brown, carinae paler. Forewing semi-translucent, brown throughout, with blackish brown spots on end of longitudinal veins. Hind tibiae pale brown and abdominal sternites dark brown.

Head and thorax. Vertex ( Figs 54C , 55A ) broad, 2.1 times wider than long; anterior margin truncated, posterior margin archedly recessed. Frons ( Figs 54D , 55B ) widest slightly below the level of antennae, 1.2 times as long as wide; frontoclypeal suture nearly concave into an arch; middle carina disappeared basally; lateral carinae distinct and elevated. Pronotum ( Figs 54C , 55A ) 2.0 times longer than vertex; median carina present, posterior margin nearly at right angle. Mesonotum 1.7 times longer than pronotum and vertex combined. Forewing ( Fig. 55C ) 2.5 times longer than wide, with 10 apical and 6 subapical cells; fork Sc+RP slightly basad of fork CuA 1 +CuA 2, first crossvein r-m basad 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: 6/7/8, second segment of hind tarsus with three platellae.

Male genitalia. Pygofer ( Fig. 55D, E ) symmetrical, dorsal margin concave and U-shaped ventrally, slightly widened towards apex; in lateral view, lateral lobes archedly extended caudally, medioventral process round ventrally. Anal segment ( Fig. 55D, F ), dorsal and ventral margins almost straight in lateral view, apical lobe extended ventrally, and 2.0 times longer than wide in dorsal view; anal style strap-shaped, not beyond anal segment. Gonostyli ( Fig. 55D, E, G ) symmetrical, apical part extended and apical margin rounded in ventral view; in lateral view, apex round, dorsal margin bending inwards in the middle. Aedeagus ( Fig. 55H–K ) in total with five spinose processes. Right side of periandrium with two spinose processes apically, the upper one short and apex dorsocephalically directed, the other one longer and apex ventrocephalically directed. Endosoma (=flagellum) moderately sclerotised, generally dorsally curved. Right side with a spinose process, apex ventrocephalically directed. Basal 1/3 of left side with a medium-sized spinose process, apex ventrocephalically directed; apex of left side with an extremely short spinose process, apex ventrocephalically directed.

Type material. Holotype: ♂, CHINA: Qingliangfeng National Nature Reserve (30°6’N, 118°54’E), Hangzhou City , Zhejiang Province, 26 July 2009, leg. Ting-Ting He; paratypes: 1♂, same collection area as holotype, 25 July 2009, leg. Yong Chen; 1♂, Leigongshan National Nature Reserve (26°23’N, 108°12’E), Leishan County, Guizhou Province, 11 July 2011, leg. Jian-Kun Long.

Distribution. China (Guizhou, Zhejiang).

Host plant. Unknown.

Remarks. This species is similar to N. trispina sp. nov., but differs in: (1) right side of periandrium without laminal process basally (in N. trispina , right side of periandrium with a transverse triangular laminal process basally); (2) left side of periandrium without spinose process (the latter with one spinose process); (3) basal 1/3 of left of endosoma with one spinose process (the latter without process).

Etymology. The specific name is derived from the Latin prefix “ brevus ” and noun “ spina ”, referring to the endosoma of aedeagus with an extremely short spinose process.
