Holorusia henana Yang, 1999 ( Figs 3–15 )

Holorusia henana Yang, 1999: 37 .

Diagnosis. Holorusia henana can be recognized by prescutum with three black stripes, the median one with a black mid-line, by the yellow pleura lacking of dorsal-longitudinal stripe. Wings are yellowish-brown with cells c, sc and stigma darker than the ground color. Abdomen is generally yellowish-brown, tergites one to seven of which have lateral stripes and very narrow posterior stripes. Tergite nine has a V-shaped notch medially.

Redescription. Male body length 35.0 mm, wing 42.0 mm, antenna 4.7 mm.

Head. Rostrum yellowish-brown, darker at ventral side. Nasus distinct, black apically, densely covered with brown setae. Antennae yellowish-brown, scape elongated, cylindrical, pedicel very short, flagellum 10-segmented, each flagellomere gradually smaller and shorter. Palpi black. Head yellowish-brown, occiput with indistinct mark ( Fig. 3 ).

Thorax. Pronotum yellowish-brown, darker medially. Prescutum yellowish-brown with three black stripes (grayishgreen in fresh); the median stripe with basal half gradually narrowed to base, parallel at apical half, with a dark median line; the lateral stripe oval, nearly half of length of median stripe ( Fig. 4 ). Scutum yellowish-brown, each lobe with a black stripe, median area of scutum brown ( Fig. 4 ). Scutellum yellowish-brown ( Fig. 4 ). Postnotum yellow, heavily whitish pruinose ( Fig. 4 ). Pleura yellow, without dorsal-longitudinal stripe ( Fig. 5 ). Halteres with stem yellowish-brown, knob darker. Legs with coxae yellow, trochanters, femora and tibiae yellowish-brown, the femora with brown tips; tarsi dark brown. Wing yellowish-brown, cells c and sc and stigma darker than the ground color, veins brown. Rs very short, as long as R 1+2+3, cell m 1 short-petiolate, discal cell narrow, slightly shorter than cell m 1 ( Fig. 6 ).

Abdomen generally yellowish-brown, tergites one to seven with lateral stripes and very narrow posterior stripes, tergites eight and hypopygium wholly brown. Sternites with narrow stripes on posterior margins. Hypopygium compressed and broadened ( Figs 7–8 ). Tergite nine densely covered with short setae, medially with a V-shaped notch ( Fig. 9 ). Sternite eight with posterior margin straight, without mid-posterior incision ( Fig. 10 ). Outer gonostylus flaky, widened basally and gradually narrowed to apex, rounded apically ( Figs 8–10 ). Inner gonostylus curved and narrow, basally with a strongly sclerotized prominence bearing long hairs, apically enlarged with an incision on dorsal margin ( Figs 11–13 ).

Semen pump with compressor apodeme fan-shaped, shallowly emarginated at dorsal margin ( Figs 14–15 ). Posterior immovable apodeme with two arms curved dorsally in lateral view, distinctly shorter than compressor apodeme, gradually narrowed to apex ( Fig. 14 ). Anterior immovable apodeme shorter than compressor apodeme, gradually narrowed to apex in lateral view, acute apically ( Fig. 14 ). Aedeagus elongated, tubular, two times longer than semen pump ( Fig. 14 ).
