Stenamma chiricahua
Stenamma chiricahua is a species of ant in the family Formicidae, first described by Snelling in 1973. The species epithet refers to the Chiricahua Mountains of southeastern Arizona, indicating its type locality and geographic association with this Madrean Sky Island range. As a member of the genus Stenamma, it belongs to a cryptic ant group known for occurring in cool, wet forest habitats at mid to high elevations. The Middle American clade of Stenamma, which includes this species, underwent a major taxonomic revision in 2013 that recognized 40 species, 33 of which were newly described, revealing a previously overlooked radiation of Neotropical ants.
Stenamma impar
Stenamma impar is a species of ant in the genus Stenamma, family Formicidae. The genus Stenamma comprises cryptic "leaf-litter" ants found in moderately humid to wet forest habitats across the Holarctic region, Central America, and parts of northwestern South America. Species in this genus are generally small, slow-moving, and form small colonies. Many Stenamma species are adapted to cool, wet environments at mid to high elevations, where they can be the most common ant genus in leaf-litter samples from cloud forest localities.
