Recognition.

Brownish, scathophagid-like flies, body length 4−8 mm. Body densely to moderately microtomentose and covered with long, fine setulae, especially in males. Frons with one or two upper reclinate orbital setae. Ocellar seta, medial and lateral vertical setae, and postvertical seta long and robust. Two to ten frontal setae usually arranged more or less regularly around lunula. Face with a strong, flattened median carina, antennal grooves deep. Parafacial with a patch of microtomentum at mid length (Fig. 15). Compound eye almost round in lateral view. Two pairs of strong vibrissae present, subequal in length and strength. Thoracic chaetotaxy as follows: 0−2 postpronotal setae (postpronotal setae usually absent in male of Centrophlebomyia furcata ); 1 + 1 intra-alar, 1−2 + 3 strong dorsocentral setae, 1 postalar, 2 notopleural setae, 0−1 prescutellar acrostichal setae. Scutellum long, dorsally flattened, much more developed in male than in female, with two pairs of setae, apical pair very long and strong, almost spiniform in larger males. Dorsal surface of scutellum bare. Development of scutellum in male related to body size. Propleural seta strong. Katepisternum densely setulose, with one strong katepisternal seta at upper posterior margin. Anepisternum with a row of setae along posterior margin, one of them strong. Thorax (except scutellum) very finely setulose throughout, besides the strong setae.

Wing membrane hyaline. Costa more or less spinose (i.e., with a regular row of stronger setulae interspersed with the general costal setulae), spine-like setae stronger in male than in female. Anal vein fading out well before wing margin. Legs thickly setulose in both sexes (almost woolly in male). Fore femur with 5-6 weak posteroventral setae near apex, scarcely differentiated in male. Hind femur with 2-3 anteroventral setae near apex. Mid tibia with five apical setae on ventral side: middle and lateral ones strongest. Hind tibia with one short, curved apical seta on posteroventral surface. Tarsi unmodified.

Preimaginal instars.

Described by Freidberg (1981) and below.

Distribution.

Europe, North Africa, Middle East, Russian Far East, northern India (Kashmir and Darjeeling).

Remarks.

The generic diagnosis incorporates the characters given by McAlpine (1977) based only on the type species Centrophlebomyia furcata .
