Material examined. ♂ , China , Sichuan , Baoxing, Dengchigou, 1600–1800 m , 30°22¢ 32²N , 102°49¢ 44²E , 13.VI.2014 . J.Hájek, J. Růžička, M. Tkoč lgt. ( NMPC ). Since there is very little information on Chinese continental species, below we provide a description of S. bifasciata and a revised fragment of our key ( Galinskaya & Shatalkin 2016 ) that will allow for determination of our new species, including S. strigosa n. sp. , and other species of the S. trifasciata species group. FIGURE 11. Strongylophthalmyia bifasciata Yang & Wang 1992 . Male: a—habitus, lateral view; b—head, and thorax, dorsal view; c—head, anterior view; d—head, lateral view; e—hind legs, ventral view; f—wing. Description. Male. Head . Frons black, anteriorly with yellowish matte band, width of the band equal to half of distance from fore edge of frons to fore ocellus; frontal index = 2.2. Occiput black shining in dorsal half; yellow in ventral half. Face, gena and postgena yellow. Antenna yellow, scape and pedicel brownish-yellow. Flagellomere small, rounded. Arista white, covered with short white setulae. Mouthparts yellowish; palpus yellowish, apically brownish. Two orbital setae, one ocellar seta, one postocellar seta, one inner and outer vertical setae, seven setulalike short frontal setae. Thorax black, metathorax matte, with thin punctation, covered with sparse, pale setulae; with two lateral crescent-like yellow bands, extending from transverse suture to scutellum (like in some specimens of Chyliza , Psilidae ). Postpronotum yellow. Pleura black shining; propleuron and prosternum yellow. Scutellum black matte, metanotum black shining. Two dorsocentral setae, two notopleural setae, one supraalar seta, one postalar seta, one anepisternal seta, one stout apical scutellar seta. Legs yellow; mid femur with weak apical darkening, mid tibia in middle 1/3 brownish laterally; hind femur with developed apical ring; hind tibia brownish laterally in middle 3/5. Hind coxa with small disc-shaped process on inner surface ( Fig. 11 e ). Wing with large but very weak apical darkening: its proximal margin almost reaches level ov vein R2+3 and with median transverse band on level of dm-cu. Costal index = 2. Discal index = 1.5. Medial index = 0.6. Vein r-m inserted at basal 2/5 of discal cell. Cell bm about 0.43 times as long as cell dm. Calypter yellowish with fan of very long yellowish setulae on margin. Halter with whitish knob and brownish stem. Abdomen laterally yellow, dorsally black; abdominal tergite five black shining. Lengths . Body, 3.8 mm ; wing, 3.2 mm .
