Stenomorpha hirsuta

Identification relies on the combination of dense body setae (hairs) that distinguish it from most other Stenomorpha species, which are generally less hairy. The elongate body form and western North American distribution help narrow possibilities. Examination of male genitalia may be required for definitive identification, as is common in Tenebrionidae. Similar species in the genus Stenomorpha can be separated by their relatively glabrous (smooth, non-hairy) integument. Dissection and comparison with type specimens or authoritative keys is recommended for certain identification.

Western North America. Specific range details are poorly documented, but the genus Stenomorpha is centered in the southwestern United States and adjacent Mexico. Records likely include arid and semi-arid regions of California, Arizona, Nevada, and possibly neighboring states.

• Other Stenomorpha speciesShare elongate body form and western North American distribution, but differ in having relatively glabrous (non-hairy) body surfaces; S. hirsuta is distinguished by its conspicuous hairiness
• Other Tenebrionidae in arid western North AmericaMay share habitat and general appearance, but differ in body shape, surface texture, and lack the dense setal covering characteristic of S. hirsuta
