3.1 Pselliophora xanthopimplina Enderlein, 1921 ( Figs 1 , 7–14 )

Pselliophora xanthopimplina Enderlein, 1921 , 52: 224; Alexander, 1940a: 122; Savchenko, 1973: 209.

Pselliophora quadrivittata Edwards, 1921 , 7: 377.

Diagnosis. Generally orange yellow in coloration; prescutum orange yellow with four dark brown stripes ( Fig. 1 ); legs yellow with black apical ring; wings yellow with a dark brown cloud beneath brown stigma ( Fig. 7 ); abdomen with segments one to six orange yellow, tergites one to three with an irregular dark brown dorsal stripes, tergite eight and sternites seven and eight entirely black, hypopygium entirely black.

Redescription. Male. Length. Body 18.0 mm (not including antenna, n =1); wing 17.0 mm (n =1); antenna 6.8 mm (n =1).

Head orange. Rostrum orange with a short orange nasus. Vertex without any marking. Eyes black. Antenna 13- segmented, relatively long; scape orange, expanded apically; pedicel orange, very short; first flagellomere orange yellow with a black conical side-branch, second to eighth flagellomeres orange yellow, each with two pairs of black branches, last two flagellomeres entirely black; each of flagellomere subequal in length ( Fig. 7 ). Palpi orange with last segment black.

Pronotum entirely yellow. 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 R 3, R 4, R 5, M 1 and apex of discall cell; Sc relatively short, cell M 1 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 ). Caudal margin of sternite nine truncated in lateral view, elliptical in caudal view ( Fig. 9 ).

Semen pump with compressor apodeme fan-shaped, slightly projected medially, forming a 60° angle with posterior immovable apodeme ( Figs 13–14 ). Posterior immovable apodeme slightly longer than compressor apodeme, gradually narrowed to apex, curved dorsally in lateral view ( Fig. 14 ). Anterior immovable apodeme gradually narrowed to apex, very short ( Fig. 14 ). Aedeagus tubular and elongated, almost three times longer than semen pump, acute apically ( Fig. 14 ).

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 .
