Which one? - Corydalus texanus
San Ysidro, Sandoval County, New Mexico, USA
July 25, 2018
Service Station. I read here in B.G. that both species may be found in New Mexico. Which characteristic(s) are used to tell them apart? Thanks for any further information/placement.

Which other?
Mark, where did you see that New Mexico had two species? So far as I can tell, four species are known from the USA: one only in TX, one only in AZ, and one only from TX eastward. That would leave C. texanus as the only one known from NM, unless the AZ species has expanded....

From BG info
page for texanus; sw. US (CA to CO-TX) to Central America (overlaps with C. cornutus in TX & NM)(1). Since there are no data points for NM, I though it best to leave at Genus. Is it okay to move or is another photo needed to confirm ID? Thanks.

I'd say male texanus
It seems safe to call this a male C. texanus. The mandibles are far too short for males of the other species, but too straight and untoothed for a female. On top of that, the NM record of cornutus is based on one specimen in the Museum of Comparative Zoology; there are no records on either BugGuide or iNat that I have found yet, so if it is still present in the state, it is far rarer than texanus.
