Strumigenys superstes Booher & Uhey 2020

Distribution. USA; Arizona.

Comments. This species is a most unusual Strumigenys and is known from a single dealate queen collected in a pitfall trap between Flagstaff and the Grand Canyon between late June and mid-July. Strumigenys superstes belongs to the excisa species-group, a morphologically distinct clade of shiny short-mandible species that once belonged in the genus Glamyromyrmex (Booher et al. 2021; Booher & Uhey 2020). Strumigenys superstes was collected in an undisturbed arid pinyon-juniper woodland on the Colorado Plateau. All other excisa species-group members have ranges in the Neotropics.
