Neocarpia longispina sp. nov.

( Figs 59‒60 )

Description. Body length: male 5.6 mm (n = 1).

Coloration. General color brown ( Fig. 59A–E ). Eyes dark brown, ocelli light yellow, semitransparent. Vertex dark brown with carinae yellowish white. Face generally yellowish brown. Pronotum yellowish brown to brown. Mesonotum with area between lateral carinae yellowish brown, lateral areas brown to dark brown. Forewing semi-translucent, brown, a blackish brown spot on the fork Pcu+A 1, basal 1/3 of forewing with an oblique brown strip, a V-shaped pale brown stripe around the stigma and small brown spots on the ends of longitudinal veins, stigma yellowish brown. Hind tibiae light yellow and abdominal sternites brown to dark brown.

Head and thorax. Vertex ( Figs 59C , 60A ) broad, 2.6 times wider than long; anterior margin straight, posterior margin archedly recessed. Frons ( Figs 59D , 60B ) widest at the level of antennae, with length almost equal to width; frontoclypeal suture nearly concave into an arch; middle carina complete; lateral carinae distinct and slightly elevated. Pronotum ( Figs 59C , 60A ) 2.8 times longer than vertex; median carina distinct, posterior margin nearly at right angle. Mesonotum 1.6 times longer than pronotum and vertex combined. Forewing ( Fig. 60C ) 2.3 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 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: 6/8/8, second segment of hind tarsus with 3 platellae.

Male genitalia. Pygofer ( Fig. 60D, E ) symmetrical, dorsal margin concave and U-shaped, slightly widened towards apex in ventral view; in lateral view, lateral lobes arched caudally extended, medioventral process triangular in ventral view. Anal segment ( Fig. 60D, F ) broad, tubular, dorsal margin waved, ventral margin nearly straight, apical lobe triangular in the middle in lateral view; 2.0 times longer than wide in dorsal view; anal style finger-shaped, slightly beyond anal segment. Gonostyli ( Fig. 60D, E, G ) symmetrical in ventral view; in inner lateral view, dorsal margin bending inwards in a right angle in the middle, apical part extended, apical margin traverse. Aedeagus ( Fig. 60H–K ) with total of six processes. Right apex of periandrium with a long spinous process, slightly waved and apex ventrocephalically directed; left apex with a slender spinous process, straight, apex left-dorsocephalically directed; left base with a triangular laminal process, directed to the left. Endosoma (=flagellum) moderately sclerotised, relatively long, generally curved to the left, the dorsal margin with a medium-sized spinous process in the middle, apex left-dorsocephalically directed; apex with two spinous processes, one short and small, ventrocephalically directed, the other broad and long, strongly curved and right-ventrocephalically directed.

Type material. Holotype: ♂, CHINA: Chaping Township (31°41’N, 104°17’E), Anzhou District, Mianyang City , Sichuan Province, 19 July 2010, leg. Pei Zhang.

Host plant. Unknown.

Distribution. China (Sichuan).

Remarks. Male genitalia of N. longispina sp. nov. are similar to those of N. trispina sp. nov., but differ in: (1) right apex of periandrium with one spinous process (the latter with two spinous processes); (2) the triangular laminal process on the left side of periandrium (the latter on the right side); (3) the ventral margin of anal segment nearly straight in lateral view (in N. trispina , ventral margin of anal segment with two triangular processes in lateral view).

Etymology. The specific name is derived from the Latin prefix “ long ” and noun “ spina ”, referring to the right apex of aedeagal periandrium with a very long spinose process, which is nearly as long as the periandrium.
