This European species closely resembles 

 the above, having the 

 tubercle on the hind coxse 

 of the female, and the

a tubercle. This species and the following superficially resemble 

 C. ovata, but are distinguished by the form of the carina at the front 

 of the malar space, as well as by having the inner side of the hind 

 femora impunctured and with a tubercle near base. It is a parasite 

 of flies of the family Sarcophagidae, which are scavengers on the dead 

 pupae of the gipsy moth.
