description: Neocarpia bidentata sp. nov.
(Figs 1–13)
Description. Body length (from apex of vertex to tip of forewings): male 5.1–5.3mm (n = 2), female 5.7–5.9mm (n = 3)
Coloration. General color brown (Figs 27–29). Eyes blackish brown alternating with yellowish brown. Ocelli pale yellow, semitransparent, with surroundings reddish. Vertex generally dark brown, carinae bright yellow (except apical transverse carina crineous). Frons tawny to tan, color becoming deeper from base to end; lateral carinae black brown, median carina brightly yellow; areas near two ends of frontoclypeal suture with two glassily yellow splashes. Rostrum yellow, apex dark brown. Pronotum with discal area and carinae glassily yellow, the rest area tan. Mesonotum with area between lateral carinae glassily yellow, lateral area tan, carinae brightly yellow. Forewing pale brown, semihyaline; an oblique brown stripe arising from base of costal cell to middle of Y-vein, another V-shaped brown broad stripe on apical half of forewing; costal cell with two small spots; a short black brown elongate spot behind stigma. Hind tibiae yellow, apexes of apical spines dark brown. Abdomen blackish brown alternating with yellow ventrally.
Head. Vertex (Figs 1, 28) broad, 1.5 times wider than long; anterior margin truncated, posterior margin archedly recessed and middle with a small gap; median carina dividing vertex into two areolets which slightly hollowed. Frons (Figs 2, 29), widest more or less around the peak of frontoclypeal suture, 1.5 times longer than wide; anterior margin nearly concave into an obtuse angle; lateral carinae distinct and elevated, S-shaped. Rostrum reaching hind femur, subapical segment 1.3 times longer than apical segment.
Pronotum and mesonotum. Pronotum (Figs 1, 28), 1.2 times longer than vertex; median carina indistinct, reaching anterior and posterior margins; posterior margin concave, forming an obtuse angle. Mesonotum (Figs 1, 28) 1.7 times longer than pronotum and vertex combined.
Wings. Forewing (Figs 3, 27) 2.5 times longer than wide, with distinct tubercles which situated along veins, with 6 subapical cells; crossveins not in rows; fork Sc+ RP slightly basad of fork CuA1+CuA2, first veinlet r+m basad of fork MA+MP; RP 2 branches, MA 3 branches, MP 2 branches; fork PCu+A1 basad of center of clavus; fork MA1+MA2 basad fork MP1+MP2.
Legs. Hind tibia with 5 apical spines; chaetotaxy of hind tarsi: 7/8.
Abdomen. Pygofer (Figs 4, 5), dorsal margin shallowly concave and U-shaped in ventral view, widening from base to apex; in lateral view, lateral lobes archedly extended caudally, outer margin with setae. Medioventral process (Fig. 5) 1.4 times wider than long in ventral view, reaching to one third of length of lateral lobes. Anal segment (Figs 4, 6, 7), in lateral view, dorsal margin nearly straight, ventral margin waved; in caudal view, dorsal margin archedly convex, ventral margin waved; 1.7 times longer than wide in dorsal view; closely connected with pygofer, unmovable. Anal style finger-like, not beyond anal segment. Genital styles (Figs 4, 5, 8), apical part with setae; in ventral view, machete-like, widening to apex, not touching each other, both inner and outer margins waved; in lateral view, both dorsal and ventral margins bending up, with a small cornuted production; loosely connected with connective, movable freely. Aedeagus (Figs 10–13) with structure simple; ventral margin with a small triangular spine at basal one third, directed ventrocaudad; both right and left sides of aedeagus shaft with a long and broad spine, both spines directed dorsocephalad; dorsal margin of aedeagus with a shovel-shaped process, directed dorsad. Flagellum strongly sclerotized, generally curving left side, base broad, narrowing to apex, forming a longer spine, which with with two denticulations on base. Connective (Fig. 9) broad and large, aedeagal shaft as wide as connective plus ventral arm.
Type material. Holotype: 1 3, CHINA: Linjiang (28°19´N, 106°12´E), Xishui County, Guizhou Province, bamboo, 1 June 2006, X.-S. Chen; paratypes: 3 ƤƤ, same data as holotype; 1 3, Dayi (25°10´N, 106°06´E), Wangmo County, Guizhou Province, bamboo, 24 Sep. 1997, X.-S. Chen.
Host plant. Bamboo.
Distribution. Southwest China (Guizhou Province).
Remarks. This new species is similar to N. hamata sp. nov., but differs in: (1) Forewing with an oblique brown stripe arising from base of costal cell to middle of Y-vein, a V-shaped brown broad stripe on apical half, and another short black brown microscler spot behind stigma, costal cell with two small spots (with only one small spot slightly basad of fork PCu+A 1 in hamata); (2) Aedeagus with two spines near apex, ventral margin with a small triangular spine at basal one third, spine on dorsal margin shovel-shaped, directed dorsad (in hamata, aedeagus with three spines near apex, base of ventral margin with two folioles whose margin saw-toothed, spine on dorsal margin hook-like, directed caudad); (3) The base of spine near apex of flagellum with two denticulation (lacking in hamata).
Etymology. The name is derived from the Latin words “ bidentata ”, which refers to base of spine near apex of flagellum with two denticulation.
