another stumper - Pentaria

another stumper - Pentaria
Organ Mountains foothills, Dona Ana County, New Mexico, USA
August 11, 2006
Size: est. 2.5 - 3.5 mm
Came to UV lights. This beetle was one of many that died before I could study it alive, probably due to collecting large numbers of carabids that let off defensive chemicals in the collecting bottle, effectively gassing themselves and many other beetles to death. I don't know what family this one might belong to.

Darren Pollock at Eastern New Mexico University, who wrote the section on Scraptiidae in American Beetles, says, "definitely an anaspidine scraptiid, likely in the genus Pentaria. If the front and middle legs have a distinct 4th tarsomere, then it's almost certainly Pentaria." I've forwarded his remarks to NMSU in Las Cruces where the specimen resides so they can count the tarsomeres, time permitting.

I have found only one Pentaria image on the Web, P. trif*asciata, and while the markings bear a little similarity, I would rule out that species for now.

There are four Pentaria species listed for New Mexico: trif*aciata, dis*par, fus*cula, and pal*lida.

Moved from Beetles.

One of the scraptiid genera that isn't in New England.

Thank you, Don.
I'll try to get it pinned down further.
