Neivamyrmex longiscapus

Jack Longino reports that he knows this species from two males collected during a Project ALAS light trapping program in 1998-1999. He also has an earlier record based on material collected by Brian Brown and sent to Julian Watkins for identification. The species is known only from males.

Borgmeier (1955) suggested it was close to Neivamyrmex pilosus. Since the worker of Neivamyrmex impudens was close to the worker of N. pilosus, he suggested N. longiscapus might be the male of N. impudens.

CO1 (DNA barcode) sequence data (courtesy Alex Smith and BOLD) confirm that N. impudens workers and N. longiscapus males from a site in Guatemala are the same. Jack now considers N. longiscapus a junior synonym of N. impudens and has changed his specimen database accordingly.
