- Schmiedeknecht 1906/1908 : in "Opuscula Entomologica" - Part 1/6 (p.1/413)
Our capture is a ♀, because there are 6 visible Sternits (see the photo), the ♂ having 8 visible Sternits. --- The Abdomen is apically acute and the apex of last Sternit is distant from apex of Abdomen Thus our capture is an Ichneumoninae, an Oxypygi Wesmael ----- The criteria allowing to identify the capture are : - The Antennae are semi-ringed with white - The Scutellum is ivory - The Coxae 3 have not Scopa (see the photo) - Femora & Tibiae are reddish (except the apex of Tibiae 3 blackish) - Postpetiole closely punctuate (but badly visible on our photo) - Tergits entirely black, except the last one ivory We obtain, after a lot (...) of stages, the identification. --- digrammus was also captured in Italy ===== NB - this sp. is : - Barichneumon for Perkins - Melanichneumon nudicoxa for Constantineanu - Ichneumon balearicus & nudicoxa for Schmiedeknecht
