The highest latitude of this mountain is 1864 m. It is not only an internationally famous tourist attraction, but also a repository of biological resources with rich species and diversified ecosystems (Zheng, 1983). The fauna of crane flies in Mountain Huang was relatively poorly documented in the previous studies. From the year of 2012 to 2015, crane flies species in this area were investigated during the field practice of undergraduates of Anqing Normal University. In the present work, six known species and two undescribed species were found. The males of four species, Pselliophora xanthopimplina Enderlein, 1921, Tanyptera hubeiensis Yang & Yang, 1988, Tipula coxitalis Alexander, 1935, and Tipulodina xyris (Alexander, 1949), are redescribed and illustrated, with new morphological characters. All of the species are reported from Anhui Province for the first time. A key to all species is provided. 2 Materials and methods The specimens examined in the present study were pinned specimens, which were collected from Mountain Huang, Anhui Province. The genital segments of the specimens were soaked in 10% NaOH overnight, observed or drawn in glycerin jelly with a Leica MZ125 stereomicroscope (Leica, Germany), preserved in glycerin jelly in 0.20 ml centrifuge tubes at last. All measurements are given in millimeters (mm), made with the aid of a digital caliper.

The terminology and methods of description and illustration followed Alexander & Byers (1981) and Frommer (1963). 3 Results 3.1 Pselliophora xanthopimplina Enderlein, 1921 (Figs 1, 7–14) Pselliophora xanthopimplina Enderlein, 1921, 52: 224; Alexander, 1940a: 122; Savchenko, 1973: 209.

Prescutum orange yellow with four dark brown stripes, lateral stripes broad and rounded apically, median stripes separated by a narrow line and gradually narrowed to hind margin (Fig. 1). Scutum orange yellow, each lobe with two black areas, the apical one triangular, the basal one elliptical. Scutellum orange yellow. Postnotum orange yellow with black semicircular spot at hind margin. Pleura entirely orange yellow. Legs stout, coxae and trochanters ochreous, front and middle femora ochreous with the tip black, the remainders of front and middle legs brownish black, hind femora ochreous with black apical ring, hind tibiae brownish black with a narrow whitish subbasal ring, hind tarsi entirely brownish black (Fig. 7). Wings yellow, cell Sc darker yellow than ground color, stigma dark brown, beneath it with a dark brown cloud extending across bases of cells R3, R4, R5, M1 and apex of discall cell; Sc relatively short, cell M1 sessile (Fig. 7). Abdomen with segments one to six orange yellow, tergites one to three with irregular dark brown median stripes, tergite eight and sternites seven and eight entirely black (Fig. 7). Hypopygium entirely black. Tergite nine with a U-shaped notch medially at hind margin, which produced into a pair of coniform processes in lateral angles, a semicircular process arising from the median area. A pair of quadrilateral lobes on the ventral margin of tergite nine, a horn-shaped process protruding from the lateral angle of lobe, beneath it with a pair of triangular lobes which has several teeth in the inner margins (Figs 8–10). Outer gonostylus falciform, narrowed apically and widened basally (Fig. 11). Inner gonostylus terminated into a black horn-shaped process (Fig. 12).

Material examined. 1♂, Anhui Province, Mountain Huang, Hougu, 22 May 2012. Distribution. China (Anhui, Zhejiang, Fujian, Sichuan, Guangdong). Remarks. In the original description of Pselliophora xanthopimplina, Enderlein (1921) recorded its type locality as ‘Tsha-jiu-san’. This name can’t be traced on any modern Chinese map. According to Mazzoldi & Jäch (2003) and Ueda & Koiwaya (2007), the correct spelling of ‘Tsha-jiu-san’ should be ‘Tsha yuen shan’, which is located between Shaoguan City and Shixing County, Guangdong Province. Therefore, we add ‘Guangdong’ to distributing area of P. xanthopimplina. 3.2 Tanyptera hubeiensis Yang & Yang, 1988 (Figs 2, 15–23) Tanyptera hubeiensis Yang & Yang, 1988, 10: 71, fig. 2; Yang & Gao, 2005: 710.
