3.2 Tanyptera hubeiensis Yang & Yang, 1988 ( Figs 2 , 15–23 )

Tanyptera hubeiensis Yang & Yang, 1988 , 10: 71, fig. 2; Yang & Gao, 2005: 710.

Diagnosis. Generally black in coloration; head black; prescutum orange yellow with three black stripes ( Fig. 2 ); wings whitish and transparent with stigma black, beneath it with a brownish cloud ( Fig. 15 ); abdominal tergites one and two ochreous with an irregular black dorsal stripes, tergites three to eight almost black, sternites one to five ochreous with irregular black median stripes, sternites six to eight entirely black; hypopygium entirely black, broad in lateral view.

Redescription. Male. Length. Body 14.0 mm (not including antenna, n =2); wing 13.4 mm (n =2); antenna 3.5 mm (n =2).

Head brownish black. Rostrum brownish black without nasus. Eyes black. Antenna 12-segmented, relatively long; scape black with apical half expanded, pedicel black, very short, first flagellomere black with two conical processes on both ends, second to ninth flagellomeres entirely black with a pair of branches on base and one branch on apical, each of flagellomere subequal in length ( Fig. 15 ). Palpi black.

Pronotum yellow medially, black laterally. Prescutum orange yellow with three black stripes, lateral stripes elliptical, median stripes widened apically, all stripes not extending to the hind margin ( Fig. 2 ). Scutellum orange yellow. Postnotum orange yellow with black hind margin. Pleura orange yellow to brownish black, anepisternum and katepisternum suffused with brownish black at ventral margins ( Fig. 15 ). Legs stout, coxae and trochanters ochreous, bases of coxae sometimes suffused with black; front and middle femora ochreous with tip black on outer surface, almost wholly black except base on inner surface, the remainders of front and middle legs black, hind femora ochreous with black apical ring, the remainders of hind leg black ( Fig. 15 ). Wings whitish and transparent with stigma black, beneath it with a brownish cloud; Sc relatively long, cell M 1 with a short petiole ( Fig. 15 ).

Abdominal tergites one and two ochreous with irregular black dorsal stripes, tergites three to eight almost black, sternites one to five ochreous with irregular black median stripes, sternites six to eight entirely black ( Fig. 15 ). Hypopygium entirely black. Tergite nine with a narrow notch in the middle, produced into a pair of angular processes ( Fig. 16 ). Sternite nine broad in lateral view, with a narrow notch in the middle in ventral view ( Figs 17–18 ). Outer gonostylus terminated into two spinous processes, the ventral one longer than dorsal one, with a spinous process on ventral margin medially ( Figs 19– 20 ). Inner gonostylus beak-shaped with a bulbiform process on inner surface, beneath it with an angular process ( Fig. 21 ).

Semen pump with compressor apodeme V-shaped, forming a 35° angle with posterior immovable apodeme ( Figs 22–23 ). Posterior immovable apodeme slightly shorter than compressor apodeme, slightly expanded at apex, curved ventrally in lateral view ( Fig. 23 ). Anterior immovable apodeme angular in ventral view, relatively short ( Fig. 23 ). Aedeagus tubular and elongated, more than three times longer than semen pump, biforked apically ( Fig. 23 ).
