A medium-sized, red and black species. It may be identified using Day (1988) and is characterised in the female by having comb-spines on the fore tarsus, those on the second segment being longer than in related species; and by the head being particularly hairy, a character best appreciated in comparative material. The genital plate of the male is relatively distinct.

It can be distinguished from the other large species, C. pseudobrevitarsis, in having very large… Read more

It can be distinguished from the other large species, C. longula, in having the spurs on the middle tibiae of about equal length.

Identification keys are given in Morgan (1984). General biology is given in Morgan (1984) and Falk (1991). The latter treats this species as a variety of C. ignita. However, C. ruddii is readily recognised by the small punctures on the second gastral tergite, relative to those on the first tergum, which are of uniform size and dispersion except at the rear of the tergum.
