description: Physiphora chalybea (Hendel, 1909) (Figs 20–26)
Diagnosis. Similar to P. longicornis in cell r4+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, 1st 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 CuA2, cell r4+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.
Material examined. Type: Syntypes: 1Ψ: Turkmenistan: “Sary Yasy / III.87 ”, “Reitter 1894 / Turkmenien”, “Chrysom. chalybea, H. / det F. Hendel”, “coll. Hendel”, “ type ” [red paper] (NHMW); 2ɗ: Turkmenistan: “Sary Yasy / III.87 ”, “Reitter 1894 / Turkmenien”, “ Chrysomyza \ chalybea, H. / det F. Hendel”, “ Typus ” (red circle) (DEI). Possible syntypes: 9ɗ, 6Ψ: Turkmenistan: “Sary Yasy / III.87 ”, “Reitter 1894 / Turkmenien”, “Chrysom. chalybea, H. / det F. Hendel”, “coll. Hendel” (NHMW).
Non­type: China: Xinjiang: 3Ψ: Tulufan, 20–140m, 8.VI.1956 (Li Changqing); 2Ψ: Alaga, RuoQiang, 850m, 8.V.1960 (Wang Shuyong) (IZCAS).
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.
