- Physiphora chalybea Chen, Xiao-Lin, 2007, Zootaxa 1398: 22-24.
Diagnosis. Similar to P. longicornis in cell r 4 + 5 narrowly opened, head brown to black, scutum and scutellum with green and blue sheen, but differing by fore leg with basitarsomere blackbrown, frons almost flat and having no conspicuous swellings.
Description.Head. Frons brown to black and subshiny, almost flat, without conspicuous swellings, often with inconspicuous shallow pits at middle; slightly wider than eye, 1.2 times as long as wide, almost parallelsided. Ocellar triangle and vertical plates black and subshiny. Ventral half of median facial plate and clypeus darkbrown, dorsal half of median facial plate and antennal groove gray microtrichose, median facial plate distinctly wider than antennal groove. Both frontoorbital and orbitoantennal microtrichose spots small, rounded. Parafacial and gena dark brown to black, gena about 1 / 3 as high as eye. Occiput and mouthparts black. Antenna blackbrown, 1 st flagellomere rounded apically, 1.5 –2.0 times as long as wide; arista bare (Figs 20–21). Thorax. Scutum and scutellum brown to black, shagreened with green and blue sheen; scutellum convex, without gray microtrichose beneath. All setae and setulae darkbrown. Wing. Completely hyaline, posteroapical extension of cell cup long, about 3.0 times as long as transverse section of vein CuA 2, cell r 4 + 5 narrowly opened (Fig. 23). Legs. Entirely blackbrown except mid and hind leg with basitarsomere yellow brown. Abdomen. Both tergites darkbrown to black, shining, with bluish and greenish sheen. Male postabdomen (Figs 25–26) similar to that of P. alceae. Female terminalia: aculeus 7.6 times as long as wide at base, slightly rounded at apex and with 1 pairs of long basal setae (Fig. 24); 3 spherical spermathecae (Fig. 22). Measurements: Wing length: 3.5 –4.0 mm. Body length 4.0– 4.5 mm.

Biology and Ecology
Biology.Krivosheina & Krivosheina (1997) recorded the larvae under the bark of dead poplars as necro and phloeophages.
Distribution.China (new record from Xinjiang); Turkmenistan, Tadjikistan. The record from Tunisia (Séguy, 1941: 116) based on five specimens with labels “Ile Djerba / 1910 / A. Weiss”, “ Chrysomyza / chalybea / Hend. / E. Séguy vid.” (MNHNP) needs further confirmation; Hennig (1940: 13) reported P. f l a v i p e s Karsch from the Island of Djerba based on additional specimens of the same series.
