Capture in “Forêt de St Prix” (Départ. Nièvre - France) - 09 VII 2013 At the place there is a cold micro-climate which is the same that the one who dominated 5000 years ago. ======= Biblio: - Berthoumieu 1894/1897 : Ichneumonides d'Europe et des pays limitrophes
- Morley 1911-1914 : in "Ichneumonologia Britannica" - Vol. I
Our capture is a ♂, because there are 8 visible Sternits, the ♀ having only 6 visible Sternits. (I was not able to make a good photo) --- The Genera are sensu Constantineanu. --- It is an Ichneumoninae, an Oxypygi Wesmael or an Amblypygi Wesmael. No criterion, allowing to know to which sub-Tribe belongs a species ♂, is decisive alone. --- Let us see the characteristics allowing to find the sub-Tribe to which belongs our capture : - The Sternits 2/4 are longitudinaly folded (I was not able to make a good photo).
Thus our capture is not an Amblypygi, but an Oxypygi. --- The additional criteria allowing to identify the capture are : - The Antennae are dorsally black - The Thorax is dorsally black, excepted : Pronotum, Tegulae & Scutellum - Femora 2 : the internal side is black-reddish, the external side is yellowish - Femora 3 : black - Tibiae 1-2 : yellowish - Tibiae 3 : yellow, apicaly ringed with black We obtain, after a lot (...) of stages, the identification. --- rufifrons was also captured in Italy
