I was not able to make more photos being given the mediocre quality of my equipment

♂ & ♀ have the same Habitus except Face

Determination of sub-Family of the ♀ :

* Characteristics of our capture :

-- Forewing with 1 Bulla

-- Inner Eye margins convergent ventrad

-- Spiracles of Petiole situated between ½ length and apex of

.... Petiole

-- Abdomen compressed

-- The Areolet of the right Forewing not open on the left

-- Propodeum reticulately wrinkled

These characteristics allow to identify the sub-Family by using :

Then www.flickr.com/photos/d-jp-balmer/13998380370/in/photolis...

So the sub-Family is Anomaloninae

 

Determination of sub-Family of the ♂ :

* Characteristics of our capture :

In the 1st quoted key, we go in sequence from 1 to 8, then we find easily the sub-Family Anomaloninae with the 2nd key.

 

Determination of Genus :
