This species closely resembles impunctatus, but the hind margin of the ninth tergite of the male is markedly convex and has a notch in the middle (it is straight or slightly concave in impunctatus) and the female has a few cibarial teeth which are absent in impunctatus. This latter character is more conveniently applied than the ratio of antennal length to wing length as stated by Campbell & Pelham-Clinton (1960). The wing pattern resembles that of impunctatus, but is more clearly defind than in that species.The female AR is 1.13-1.21, and the SD 3,11-15. It could be also be confused with C. obsoletus, but in that species the third segment of the female palp bears a single small sensory pit (there are several small pits in fagineus) and there are no cibarial teeth. See also C. subfagineus (data sheet 44). The figure of the wing is from Edwards (1939), and of the male genitalia redrawn from Delecolle (1985).
The type series, and subsequent material, was reared from wet leaf litter in beech and other tree-holes; it has also been taken at light. It is an uncommon species in the U.K. where it seems to be dependent on the presence of large, permanent tree holes; but it is fairly frequent in light trap catches from the southern Palaearctic.
From Britain through much of Europe and Scandinavia, to Russia and North Africa.
