Genus Scatophila Becker, 1869 Scatophila Becker, 1896: 237. Type species: Ephydra caviceps Stenhammar, 1844, by original designation. Centromeromyia Frey, 1954: 40. Type species: Centromeromyia eremita Frey, 1954, by original designation (synonymized by ZATWARNICKI 1991: 329). The contaminata species group Diagnosis. Face moderately produced anteriorly, not sexually dimorphic; 2–3 large setae on the facial margin and 2 distinct setae on the midface of which the ventral one is nearly as strong as the marginal (Figs 1–3, 5, 6, 13, 16, 17, 23–25); gena very narrow; anterior margin of epandrium almost straight (Figs 7, 10, 18); neohypandrium present, elongate, slightly deflected before the top (Figs 9, 12, 20); postgonite arcuately deflected, its proximal margin slightly convex, distal process of postgonite triangular, bifurcate on the top (Figs 9, 12, 20); phallus (= aedeagus) without ventral process, in dorsal view with broadly oval distal margin (Figs 8, 11, 19); anterior margin of the dorsal opening of phallus almost straight or broadly convex; phallapodeme in lateral view (Figs 9, 12, 20) refracted medially or arcuately deflected, in dorsal view generally with broad proximal extension and sharp subapical lateral process (Figs 8, 11, 19). Species included. Scatophila contaminata (Stenhammar, 1844), S. exilis Cresson, 1935, S. ordinaria Sturtevant & Wheeler, 1954, and S. pumilio (Loew, 1860). Remark. The placement of S. pumilio in the contaminata group was informally proposed by ZATWARNICKI & MATHIS (1994, illustration legend on page 364 and a remark on page 368) and is confirmed herein. Key to European species of the contaminata group 1 Body black, unicolorous (Figs 3, 5); face of male with white microtomentum (Figs 2, 5, 6), face of female shiny (Fig. 1); mesonotum uniform, without pattern (Fig. 5); phallapodeme bar-like, gradually broadened posteriorly (Figs 8, 9). ................................................. .......................... S. contaminata (Stenhammar, 1844). – Body grey with pattern on mesonotum (Figs 13, 15, 17, 22, 24, 25); face not shiny, without whitish microtomentum (Figs 13, 16, 17); phallapodeme Y-shaped or helmet-like posteriorly (Figs 11, 12, 19, 20). ....... 2 2 Acrostichal setulae similar in size (Fig. 25); margin of wing at apex of vein R 4+5 rounded (Fig. 21); knob of halter light brown; the male terminalia with epandrial anterior margin slightly rounded medially (Fig. 10), and phallapodeme Y-shaped, split posteriorly (Fig. 12). ...................................... S. pumilio (Loew, 1860) – Presutural acrostichal setulae larger than others (Fig. 15); wing slightly pointed at apex of vein R 4+5 (Fig. 14); knob of halter white; the male terminalia with epandrial anterior margin even (Fig. 18), and phallapodeme helmet-like in dorsal view (Fig. 20). ............................ .........................
