Dolichopeza (Nesopeza) jiangjinensis Men View in CoL sp. nov.
( Figs 9, 12 View Figs 7–12 , 20 View Figs 13–21 , 65–71 View Figs 65–71 )
Type locality. Simianshan Mountain, Chongqing, China, 28°39′N, 106°24′E.
Type material. HOLOTYPE: J, CHINA: CHONGQING: Simianshan Mountain, 18.v.2017, coll. Guoxi Xue, Chao Zhang. PARATYPE: 1 J, same data as holotype.
Diagnosis. Generally yellowish-brown. Prescutum yellowish-brown with three yellow stripes. Wing light grayish, glassy, stigma light brown. Leg with coxa and trochanter yellow, femur yellowish-brown with tip darker, tibia yellowish-brown with apical 1/5 whitish, tarsus wholly snow-white. Tergite nine with four processes, a pair of lateral processes horn-shaped, heavily blackened, the outer median process truncated apically, the inner median process cone-shaped, distinctly lower than the outer one; lateral borders of tergite nine produced into ridges which are broadened basally and narrowed at apical half, curved in right angle.
Description. Male. Length: body 10.0–10.2 mm, wing 10.2–10.4 mm, antenna 5.4–5.6 mm.
Head. Rostrum yellowish-brown. Nasus lacking. Antenna yellowish-brown, slightly darker than body in coloration. Palpus light yellowish-brown. Head light yellowish-brown, occiput with median region slightly darker in coloration.
Thorax. Pronotum wholly light yellowish-brown ( Figs 9, 12 View Figs 7–12 ). Prescutum light yellowish-brown with three yellow stripes ( Fig. 9 View Figs 7–12 ). Scutum, scutellum and postnotum yellowish-brown ( Fig. 9 View Figs 7–12 ). Pleuron wholly yellowish-brown ( Fig. 12 View Figs 7–12 ). Halter with stem light brown, knob darker in coloration. Leg with coxa and trochanter yellow, femur yellowish-brown with tip darker, tibia yellowish-brown with apical 1/5 whitish, tarsus wholly snow-white. Wing light grayish, glassy, stigma light brown, cells c and sc not darker than ground color, stigma light brown; veins brown, Sc ending about opposite 2/3 of length of Rs, Rs relatively short, R 3 slightly curved, about twice as long as R 2+3, cell m 1 slightly longer than its petiolate, r-m slightly longer than basal section of R
4+5
( Fig. 20 View Figs 13–21 ).
Abdomen yellowish-brown. Hypopygium brown. Tergite nine with four processes, pair of lateral processes horn-shaped, heavily blackened, outer median process truncated apically, inner median process cone-shaped, distinctly lower than outer one; lateral borders of tergite nine produced into ridges broadened basally and narrowed in apical half, curved at right angle in genital chamber ( Figs 65–67 View Figs 65–71 ). Outer gonostylus narrowed, acute apically ( Figs 65–68 View Figs 65–71 ). Inner gonostylus with process horn-shaped, directed cephalad, strongly blackened, very sharp at end, with caudal process expanded, curved and terminating at acute angle ( Figs 65–68 View Figs 65–71 ). Sternite nine with pair of strongly developed processes equipped with long setae on its dorsal surface ( Fig. 67 View Figs 65–71 ).
Semen pump with anterior immovable apodeme very expanded, narrowed anteriorly, rounded laterally in dorsal view ( Figs 69, 71 View Figs 65–71 ). Compressor apodeme fan-shaped, relatively elongated, slightly darker in coloration medially ( Fig. 70 View Figs 65–71 ). Posterior immovable apodeme forming V-shaped plane, laterally terminating at obtuse angle ( Figs 69, 71 View Figs 65–71 ). Aedeagal guide thin, gradually narrowed to acute apex ( Figs 69, 71 View Figs 65–71 ). Aedeagus slightly broadened at most base, and then gradually narrowed to truncated terminal ( Figs 69, 71 View Figs 65–71 ).
Differential diagnosis. The new species is allied to the Indian species D. (N.) capitella Alexander, 1968 (ALEXAN- DER 1968) by the venation of wing, the presence of hairy processes on sternite nine. It can be separated from the latter by the tergite nine with four processes (posterior border of tergite nine trilobed in D. (N.) capitella ), by the inner gonostylus with a strongly blackened and sharp beak (inner gonostylus without such beak in D. (N.) capitella ). Etymology. The specific name refers to the type locality of the new species, Jiangjin District, Chongqing; adjective. Distribution. China: Chongqing.
