Oliparisca menglaensis Zhi & Chen , sp. nov.

( Figs 1–27 View FIGURES 1–4 View FIGURES 5–20 View FIGURES 21–27 )

Description. Body length: male 6.1–6.5 mm (n = 2), female 7.0– 7.5 mm (n = 6).

Coloration. General color brown ( Figs 1–4 View FIGURES 1–4 ). Eyes brown, ocelli yellow. Vertex, face, rostrum and pronotum brown, mesonotum dark brown. Forewing semi-translucent, brown, stigma brown, termination of forewing blackish brown and middle 2/3 part of forewings with small irregular blackish brown patches. Hind tibiae brown and abdominal sternites brownish black.

Head and thorax. Vertex ( Figs 1, 3 View FIGURES 1–4 , 5 View FIGURES 5–20 ) broad, 1.4 times wider than long, with a distinct subapical transverse carina arc-shaped, connected with anterior border of vertex by two longitudinal small carinae, median carina only discernible at basal half behind subapical carina, posterior margin nearly excavated at right angle, lateral margins slightly elevated. Frons ( Figs 4 View FIGURES 1–4 , 6 View FIGURES 5–20 ) 0.9 times as long as wide. Frons with median carina distinct and fork of median carina near apex. Rostrum ( Fig. 2 View FIGURES 1–4 ) reaching hind femur. Pronotum ( Figs 1, 3 View FIGURES 1–4 , 5 View FIGURES 5–20 ) 1.6 times longer than vertex. Mesonotum 1.5 times longer than pronotum and vertex combined. Forewing ( Fig. 8 View FIGURES 5–20 ) 2.9 times longer than wide, with 12 apical and 6 subapical cells; RA 2 branches, RP 3 branches, MP with 5 terminals: MP11, MP12, MP2, MP3, and MP4, fork MP1+MP2 basad of fork MP3+MP4. Hind tibia ( Fig. 9 View FIGURES 5–20 ) with 5‒9 very small lateral spines; chaetotaxy of hind tarsi: 7/5, first segment of hind tarsus without platellae and second segment with 2 platellae.

Male genitalia. Pygofer ( Figs 10–12 View FIGURES 5–20 ) asymmetrical, dorsal margin concave and U-shaped ventrally, widened towards apex; left lateral lobe extended caudally and bifurcated into two spinose processes, the dorsal one much longer; right lateral lobe produced caudally, apex rounded. Medioventral process large, cup-shaped ventrally. Anal segment ( Figs 10, 11, 13, 14 View FIGURES 5–20 ) long tubular, nearly symmetrical, twice longer than wide in dorsal view; anal style strap-shaped, beyond anal segment; apical margin curving downward. Gonostyli ( Figs 12, 15, 16 View FIGURES 5–20 ) in ventral view asymmetrical, the right one much larger, widening towards apex, apical part extended and apical margin rounded. Periandrium of aedeagus ( Figs 17–20 View FIGURES 5–20 ) without process. Endosoma long, generally curving ventrally, with two processes on ventral margin. Basal process large, laminal, directed dorsocephalically; the middle one bifurcated, and each ramus branched respectively.

Female genitalia. Posterior margin of pregenital sternite ( Fig. 21 View FIGURES 21–27 ) with a large wide projection. Tergite IX ( Fig. 23 View FIGURES 21–27 ) moderately sclerotized, with a large nearly elliptical wax plate. Anal segment ( Fig. 22 View FIGURES 21–27 ) nearly round, 1.8 times longer than wide in dorsal view. Gonapophysis VIII ( Fig. 24 View FIGURES 21–27 ) and Gonapophysis IX ( Fig. 25 View FIGURES 21–27 ) thin and hair-shaped. Gonoplac ( Fig. 25 View FIGURES 21–27 ) well developed, broad, basal half fused together. Posterior vagina ( Figs 26–27 View FIGURES 21–27 ) elongate, with a long nearly cylindrical sclerite, the part in dorsal view much shorter than that in ventral view.

Type material. Holotype: ³, CHINA: Mohan Town (21°14', 101°42'), Mengla County, Yunnan Province, 21 June 2016, leg. Ying-Jian Wang; paratypes: 1³ 6♀♀, same collection area as holotype, 20–23 June 2016, leg. Liang- Jing Yang, Ying-Jian Wang and Qiang Luo.

Distribution. China (Yunnan) ( Fig. 28 View FIGURE 28 ).

Remarks. Male genitalia of O. menglaensis sp. nov. is similar to O. muluensis ( Van Stalle, 1991) , but differs in: (1) endosoma without spinose process on right side (the latter with three spinose processes on right side); (2) ventral margin of endosoma with a spinose process at basal and middle part respectively (the latter without spinose process at the same position); (3) left lateral lobe of pygofer bifurcated (the latter not bifurcated); (4) right gonostylus much larger than left one (left gonostylus longer than right one in O. muluensis ).

Etymology. The species name is derived from the name of the type locality, Mengla County in Yunnan Province.
