Chlorops strigulus (Fabricius, 1794), (Chloropidae), female. This robust species was long time included in the genus Anthracophaga Loew, 1866, now a synonym or subgenus of Chlorops. It is extremely similar to C. frontosus Meigen, 1830, most old records need re-examination. Characteristics (frontosus in brackets), unpublished results of M. von Tschirnhaus: base of arista black (yellowish-brown), behind outer vertical bristle (vte) the whole lateral occiput downwards yellow (below a yellow area eye margin black), acr dense, in the line of the dc inserting on black points (scarce, on yellow ground), palpi short, excavated dorsally (long, normal above), 3rd antennal segment bicoloured (black), tergites dark until their ventral edge (lateral yellow, ventral black again, thus, two lateral addominal stripes), scutellum slightly triangular (widely rounded), all femora more or less black, knees yellow (femora yellow with dark spots/striations), narrow dark line from the lowest point of the eye to the edge of the gena (such line absent), epandrium and surstyli bigger than the compared species (smaller). Larvae produce galls in certain Poaceae (frontosus: reared from Carex).
