Diagnosis and Notes

Vaguely marked specimens might easily be mistaken for C. obsoletus or C. imicola, but  both these species have a single small sensory pit on the third segment of the palp; in impunctatus there are a number of very small, shallow and scattered sensory pits. It could also be confused with C. fagineus (in which the female has cibarial teeth, a higher AR, and the hind margin of the male ninth tergite is convex).  The female AR is 0.96-1.11; the SD 3,11-15. Occasional specimens can be found with a trace of a dark spot in cell cu. The figure of the wing is from Edwards (1939); that of the male genitalia is redrawn from Delecolle (1985).
