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 . FIGURES 20–24. Physiphora chalybea Hendel ; 20, head, dorsal view; 21, head, lateral view; 22, spermatheca (one of three); 23, wing; 24, apex of aculeus. 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.
