Stenomorpha
Stenomorpha is a large genus of darkling beetles (family Tenebrionidae) comprising more than 160 described species and subspecies. The genus was established by Solier in 1836 and belongs to the tribe Asidini within subfamily Pimeliinae. Species-level taxonomy has been historically neglected, with no modern revision for nearly 175 years until recent work by Keller (2008) and others. The genus exhibits notable diversity in the southwestern United States and Mexico, with some species occurring in specialized habitats including California vernal pools and the Cuatrociénegas Protected Area in Coahuila, Mexico.
