The species is characterised by its subapically toothed mandible (Fig. 155), which is unique among the Nordic and Baltic species of the C. ignita group. The head and mesosoma are mainly dark blue with greenish reflections, and the metasoma is dorsally golden red or dark red. As in C. pseudobrevitarsis, the spurs of the mesotibia are approximately equal in length (Fig. 167) and the mandible is very thick (medial width more than half of its basal width in the female and more than two thirds of the basal width in the male). In the female, the metatarsus is not longer than the metatibia (Fig. 169) and the antenna is strongly nodular (Fig. 172). The punctation of T2 and the mesoscutum (Fig. 157) is sparser compared to C. pseudobrevitarsis.
