Redescription

Male

MEASUREMENTS. Body length 23.0– 24.2 mm, wing length 28.8–30.5 mm, antenna length 4.0– 4.2 mm (n = 2).

Prescutum dark brown with four stripes, all stripes with reddish brown margins, median stripes olive grey, broadened anteriorly and gradually narrowed posteriorly, stripes with abundant bluish white pruinescence on both sides. Scutum dark brown with four spots bearing bRoad bluish white pRuinescence, viRtually confluent, backgRound coloR of spots Reddish bRown, anteRioR margin of scutum with four small olive-grey spots connected with stripes of prescutum. Scutellum and mediotergite dark brown with abundant pruinescence, except posterior margin. Pleuron mainly greyish brown with extensive bluish white pruinescence. Anepisternum brown with pruinescence and with brownish black stripe on upper portion; anepimeron with a dull black spot. Setae on thorax dark brown. Legs with dark brown coxae bearing white pruinescence, trochanter with black spot ventrally, femora dark brown with dark apex, tibiae yellowish brown with dark brown apex, tarsi dark brown. Claw with a black triangular tooth basally. Setae on legs dark brown. Wing variegated grey with numerous small white, brown and bluish grey areas, veins and cell Sc pale brown, pterostigma brown, petiole of cell m 1 ⅓ as long as discal cell, long spot of cell cua daRk bluish gRey, spots dull gRey at inteRsection of veins ( Fig. 68 ). Halter with yellowish brown stem and brownish black knob.

ABDOMEN ( Fig. 65 ). Mainly dark brown. All tergites with black lateral stripes, sternites and lateral margins of tergites with white pruinescence. Setae on abdomen golden.

HYPOPYGIUM ( Figs 67 , 71–76 ). Mainly dark brown. Posterior margin of tergite 9 with a pair of tooth-like protrusions, elongate medially. Gonocoxite and sternite 9 virtually fused, except ventral surface of sternite 9 with vague suture. Aedeagus dark; adminiculum subhyaline, narrow, but apically slightly wider. Outer gonostylus roughly V-shaped, inner half of lobe folded ( Figs 73–74 ). Inner gonostylus short, pistol-shaped, with slant beak ( Fig. 75 ).

Female

MEASUREMENTS. Body length 27.4 mm, wing length 33.5 mm, antenna length 3.6 mm (n = 1).

Body color same as in male. Apex of femora slightly paler than in male. Wing color paler than in male, spots of cell r 5 varied, one wing with two spots in cell r 5 centrally, another wing with only one spot, position inconsistent with that in male ( Fig. 69 ).

OVIPOSITOR. Posterior margin of tergite 9 with a slender protrusion laterally. Infra-anal plate short. Fused valculae slender. Hypovalve short, apically slightly upturned ( Fig. 70 ).

Distribution

China (Xizang); India; Myanmar; Nepal.

Remarks

We compared the four specimens we obtained (CUA), the holotype (BMNH), and specimens from Nepal and India (Kumaon and Sikkim) (USNM). The species is not completely consistent regarding the size, location or number of dark spots within cell r 5. Even in the female specimen from Milin (CUA), the markings on the two wings are asymmetrical ( Fig. 69 ). However, what is certain is that the hypopygium of the male specimens is exactly the same.
