type description

Ratzeburg 1844

3. C. nigrinus Er.

Dem C. similis ausserordentlich ähnlich, aber verschieden durch feinere Sculptur, besonders nur punktirten, kaum runzlichen Mesomesosoma, ganz schwarze Fühler, ganz rothbraune Mittelschienen. Auch die Enden der vordern und mittlern Schenkelhöcker rötheln stark, und die Hinterschienen sind grösstentheils roth.

Er steckte unter den Exemplaren von C. similis und ist wahrscheinlich mit denselben gemeinschaftlich aus Tortrix ocellana gekommen.
