Bizarre metalllic green wasp with elbowed antennae - Eusandalum -

Camp Rock Road, 9.3 miles N of CA-247, San Bernardino County, California, USA
May 31, 2019
Size: ca 5 mm

I beat this strange female wasp from a lone tree in creosote bush habitat and collected it. It looks like it has the sculpturing of a chrysidid, but the antennae are all wrong. Can't find a match anywhere, but I'm sure someone will recognize this one immediately! :)

Moved

Moved from Ants, Bees, Wasps and Sawflies.

Thanks Ross - it looks like there are a limited number of species, this one should probably be identifiable by someone, at least from the specimen I collected.

I added -

a number of specimen images, seems to key to genus Eusandalum in the Gibson chapter of the "Annotated Keys to the Genera of Nearctic Chalcidoidea"...

It is indeed a female Eusanda

It is indeed a female Eusandalum. Based on its uniformly green body color, very long and slender last gastral tergite covering the ovipositor sheaths, and lack of a postmarginal vein in the foe wing it appears to be Eusandalum cyaneum (Ashmead). However, this genus requires a species revision.

Calosotinae…
