Chalcid 2 - Epitranus clavatus - female

Chalcid 2 - Epitranus clavatus - Female
Pulaski County, Kentucky, USA
May 29, 2011
Size: 3 to 4 mm
An interesting chalcid that I can't quite place. Antennae inserted very low on the face, narrow elongate petiole, and apex of hind tibiae extended as sharp point.

I asked Dave Smith about this and he forwarded my question to Eric Grissell, who says "It's an Epitranus and almost certainly clavatus."

It certainly does look like a
It certainly does look like an Epitranus, though I have never really worked with chalcidids. Epitranus is an Old World genus and the first record in North America was not until Grissell and Smith (2003) and Hoebeke et al. (2003) discovered E. clavatus (Fabricius), reporting it from North Carolina and West Virgina. According to them the species likely was introduced into the USA along with its primary host, clothes moth, in clothing or carpeting. Unfortunately we do not have a specimen of this specie in our collection.

Thank you, Dr. Gibson...
It's stunning to me that the 2003 discovery of this species was the first one in the Western Hemisphere in the last 100 years. A rare find indeed. This is apparently a female based on the structure of the pedicel.

Moved from Chalcidid Wasps.

possibly Epitranus…
This genus of Chalcidinae is described as having a long, slender, and striated pedicel with a gaster that is compressed and bulges ventrally. The insertion points of the antennae are close to the mouth on the base of a protruding clypeal shelf. Additionally, the forewing appears to have a long marginal and short stigmal vein. Will wait on a confirmation for this one.

looks like it

re: confirmation...
I emailed Dr. Gibson about this one to see if he agrees.

thanks Ross
I went ahead and moved to species page since I feel fairly confident about it.
