This subject came to a mercury vapor lamp set-up at 33°22'01.3N 108°04'23.4W, 6846 ft elevation, Wall Lake 7.5' quadrangle, about 1.5 miles north of Wall Lake near State Route 61 (Forest Road 150), Gila National Forest, Catron Co., NM. Many other images from this event are posted. I collected representative specimens of most, and can follow up with high resolution images of selected ones if needed.

Followup: I posted spread specimen images that allowed me to identify the species. From the key to species of Neoheliodinesin Hsu & Powell 2004(1), the lead colored FW spots, with none white, and the metallic gray distal boarder with an indented knotch identify it as N. cliffordi or N. arizonense. Dissection is needed to key it further. However, the detailed descriptions in this reference allow them to be distinguished by the pigmentation of the labial palpus visible in my head view (last image). The distal segment is metallic dark gray for the former and pale yellowish white for the latter. This implies my specimen is N. arizonense. Also note that the the white pigmentation at the end of the antennae seen in BG images of N. cliffordi is longer than for N. arizonense. My specimen's antenna tips look like those of N. arizonense. Finally, the authors state that reports of N. cliffordi in NM "may refer to N. arizonense by present concepts".
