I collected a male and female this species on Embudo Trl. (No. 193) between 6000 and 7000 ft elevation in Tijeras 7.5’ quadrangle, Sandia Mountains, Bernalillo Co., NM. The male is posted here:

They appear to be Tragidion auripenne based on the keys, images, and range data of Swift and Ray 2008(1). Expert confirmation is appreciated.

This image is derived from a stack of 77 images with a 170 µm step taken with a Nikon 200mm F4 ED IF macro lens set to F5.6 + Nikon D300 camera, and processed with CombineZP software.

Moved from Tragidion densiventre.

Bruce Tilden is nonresponsive. Here are some good pictures of T. densiventre for comparison:

From Swift and Ray (1), T. densiventre may be distinguished from T. auripenne by having elytra that narrow to the apex and costae that curve inward toward the suture. Elytra margins are much more parallel and costae straighter in T. auripenne. T. densiventre is also reported here to be larger in size. I have two females of T. densiventre specimens, and this is indeed the case (19 mm and 20 mm vs. 16.4 mm for the subject).
