French Guianan evanioids

December 4th, 2010 3 comments

Today I had a request for some specimens of Evaniidae from Ricardo Kawada, a PhD student and researcher in Sao Paulo. This forced me to go over my French Guianan evanoids and I thought that I would take some photos while I was at it:

* many thanks to Ricardo Kawada & David Smith for help with the identifications.

Foenomorpha senlura (Cenocoeliinae, Braconidae)

I have extracted a few evanoid-like braconids from the recent French Guianan batch and amongst the Cenocoeliinae I found a few of these, which I didn’t think was related but Yves Braet (an expert on French Guianan braconids) suggested Foenomorpha and after a bit of Googling I found a key (by Yves) that suggests that this is Foenomorpha senlura – it feels amazing to get a species-level identification for a neotropical wasp :D

Capitonius sp. (Braconidae, Cenocoeliinae) – an evanoid ‘mimic’

October 30th, 2009 No comments

Amongst the evanoid wasps I have found quite a few of these little wasps. At first I thought that they must be evanoids because the gaster is mounted very high on the propodeum but on closer inspection they have fused costal veins and so they actually key (in Goulet & Huber, 1993) to Braconidae. Then in the key to braconid subfamilies (Acterberg, 1993) they go to an unusual little family called Cenocoeliinae. Of course, they aren’t true mimics but they have evolved a similar arrangement of gaster & propodeum to the evanoids.
