description: Ptychoptera qinggouensis sp. nov.
(Figs. 20–26)
Diagnosis. Hypandrium bilobate, each swollen and semicircular at base, with very long dense hairs and one long bristle at middle; apical part of lobe with a finger-like projection; gonostylus with a pear-like projection at base, with short dense hairs; medial part with a horn-like projection, broad at base, acute at apex; distal part with a finger-like projection, with long hairs.
Description. Male. Body length 9.0 mm, wing length 8.0 mm. Head mostly yellow, except vertex black; hairs on head black. Compound eyes black without pubescence. Antenna with scape, pedicel, first flagellomere and base of 2nd flagellomere yellow, other flagellomeres brown; antenna with uniformly black hairs. Proboscis yellow with black hairs. Palpus yellow, with black hairs.
Thoracic dorsum mostly black, except scutellum and postnotum yellow; postnotum with a patch of dense black hairs anteriorly; mesopleuron uniformly yellow without hairs. Coxae and trochanters uniformly yellow; femora yellow at base, dark brown apically; tibiae mostly yellow except apical part dark brown; base of first tarsomere yellow, gradually darkened apically, 2nd to 5th tarsomeres dark brown. Hairs on legs black. Relative length of 1st to 5th tarsomeres in hindleg as 11.2: 2.5: 1.5: 1: 1. Wing (Fig. 21) 3.5 times as long as wide, subhyaline. Wing marked with one narrow band and three brown clouds as follows: band extending from basal of R2+3 to m-cu; basal cloud along basal of Rs; subapical cloud along apical of R1; apical cloud along basal of R4. Veins brown. Venation: Sc ending in C at level of basal 1/3 of R2+3; Rs long, about 5 times as long as r-m. Haltere yellow brown, with black hairs. Prehaltere yellow brown.
Abdomen: 1st to 5th terga mostly yellow, with brown posterior margins; 5th to 7th terga brown; 8th tergum brown at base, yellow at apex; 1st to 5th sterna yellow, 6th to 7th sterna brown. Hairs on abdomen black. Male genitalia (Figs. 22–25): Epandrium with a pair of posterior projections, projection simple, broadest at base, tapering and curve distally. Hypandrium bilobate, lobe swollen, semicircular at base, with long dense hairs and one long bristle on the edge of middle part; apical part of lobe with a finger-like projection. Gonocoxite swollen ventrally. Gonostylus with a pear-like projection at base, with short dense hairs; medial part with horn-like projection, broad at base, acute at apex; distal part with a finger-like projection, with long hairs. Paramere short, meniscus-like.
Female. Body length 9.5 mm, wing length 9.5 mm. Resembling male. Terminalia (Fig. 26): Cercus blade-like, 1.67 times as long as 8th sternum, 8th sternum 1.5 times as long as 7th sternum.
Type material. HOLOTYPE: 3, CHINA, Neimenggu, Tongliao, Kezuohouqi, Daqinggou, 160 m, 2011. VIII.5, Junchao Wang. PARATYPES: 83 7ƤƤ, same data as holotype.
Distribution. China (Neimenggu).
Etymology. The specific name refers to the type locality Daqinggou.
Remarks. This new species is somewhat similar to P. clitellaria Alexander, but can be easily separated from it by wings having three clouds as follows: basal cloud being along basal of Rs; subapical cloud being along apical of R1; apical cloud being along basal of R4. In P. clitellaria Alexander, wings only have two clouds, of which one is along the basal of R4 and the other is along the fork of vein M (Krzeminski & Zwick 1993).
