Tipula (Acutipula) buboda Yang and Yang, 1992: 263 . Type locality: China: Hubei (Shennongjia)

Diagnosis. Pleura dark brown with grayish pollen. Tergite 9 with median lobe basally about 1/3 width of tergite 9, apically conspicuously constricted but relatively broad and truncated, bearing black spicules. Sternite 8 with posterior margin not produced, with abundant long yellow setae subterminally. Clasper of gonostylus with basal beak obtuse at tip; outer beak produced subapically, relatively short and stout; apex of clasper of gonostylus with dense long coarse yellow setae.

Description. Male. Body length 16–18 mm, wing 19–20 mm.

Head. Rostrum dark reddish brown, with slender nasus. Vertex dark yellowish brown, occiput blackish brown. Orbits paler. Pollen on head grayish white. Hairs on head black. Antenna nearly 6 mm long; scape and pedicel brownish yellow; flagellum blackish brown, each basally slightly enlarged except first one, verticils nearly as long as corresponding segments. Probocis blackish brown; palpus blackish brown, with black hairs.

Thorax. General brown with grayish white pollen. Pronotum dark brown; prescutum grayish brown, with four dark grayish brown longitudinal stripes, lateral ones shorter and wider, either side with sparse hairs; anterior and lateral margins of prescutum dark reddish brown; median area of V-shaped transverse mesonotal suture dark reddish brown; scutum grayish brown, each lobe with two dark brown spots, hairs on lateral margins; scutellum and mediotergite dark grayish brown. Pleura dark brown with grayish pollen; laterotergite dark brown with yellowish pollen. Hairs on thorax yellowish brown. All coxae and trochanters yellow with dense yellow hairs; femora brownish yellow with tips dark brown; tibiae yellowish brown with tips dark brown; tarsi yellowish brown except last three segments dark brown; tibial spurs 1–2–2; claws black, each with a reddish brown basal tooth and a black median tooth. Hairs on legs black. Wing ( Fig. 5 ) grayish yellow, almost transparent. Cells C and Sc yellowish brown; stigma brown; area from stigma to cell dm along cord white; cell bm with a light gray cloud at tip and white area inside; cell CuA2 with a light brown spot at middle and white areas at both sides of the spot. Veins dark brown. Halter dark brown.

Abdomen. Tergites 1–5 dark brownish yellow, with brown longitudinal stripes near lateral margin; sternites 1–5 yellow. Segments 6–9 blackish brown. Hairs black on tergites, yellow on sternites.

Hypopygium ( Figs. 22–25 ). Tergite 9 ( Fig. 25 ) with median lobe basally about 1/3 width of tergite 9, apically conspicuously constricted but relatively broad and truncated, bearing black spicules. Sternite 8 with posterior margin not produced, but with abundant long yellow setae subterminally. Lobe of gonostylus ( Fig. 24 ) flattened, nearly rectangular, with apex truncated. Clasper of gonostylus ( Fig. 23 ) with basal beak obtuse at tip; outer beak produced subapically, relatively short and stout, with dense setae at tip; apex of clasper of gonostylus with dense long coarse yellow setae; posterior margin of clasper of gonostylus with a sharp compressed process near middle.

Female. Unknown.

Specimens examined. Holotype male, Hubei: Shennongjia, Dayanwu (31° 28' N, 110° 24' E), 1984. VI. 29, Jikun Yang. Henan: Luoyang, Songxian, Baiyun mountain (33° 40' N, 111° 52' E), 2002. VII. 25 (light trap), Ding Yang, 1 male; Henan: Luoyang, Songxian, Tianchi mountain (34° 14' N; 111° 51' E, 1330 m), 2004. VII. 12, Hui Dong, 2 males; Henan: Luoyang, Luanchuan, Longyuwan (33° 43' N, 111° 46' E), 2004. VII. 21, Kuiyan Zhang, 1 male.

Distribution. China (Henan, Hubei).

Remarks. This species is very similar to T. bubo Alexander, 1918 from Russia and Japan. But it differs from bubo in the shapes of the median lobe of tergite 9, the lobe of gonostylus and the posterior margin of the clasper of gonostylus. In bubo , the median lobe of tergite 9 is round at tip while not constricted near tip; the apex of the lobe of gonostylus is round; the posterior margin of the clasper of gonostylus is smooth without any sharp process ( Savchenko 1961).
