Some confusion exists on the synonymy of reconditus, riouxi and segnis. C. riouxi and reconditus are often either treated as separate species or as synonymous. However I prefer to regard riouxi as a junior synonym of segnis. The male parameres of both these species curve downwards with a 180 degree bend half-way along; the sole difference being a long tuft of hairs at the distal ends of the parameres in riouxi. The parameres of segnis usually show a line of sockets where these hairs have broken off. The female of riouxi is said (Delecolle 1985) to have sensilla on 3-10, as in reconditus; but the females of these species are otherwise identical in appearance. Further, Delecolle (1985) gives figures of the abdominal sclerites of all three species, and those of riouxi resemble segnis but not reconditus.
The wings are greyish, unmarked, and the third segment of the palp is swollen with a large deep sensory pit. The AR is 1.07-1.14; the SD 3-14.
The figure of the wing is from Delecolle (1985) and of the male genitalia from Campbell & Pelham -Clinton (1960).
The early stages of either this species or reconditus were figures by Kettle & Lawson (1952).
Widespread in Europe from Ireland and Britain, Spain, through to Russia.
Nothing known.
