Strumigenys erikae

This species occurs in mature cloud forest. It is known from two workers from two different Winkler samples of sifted litter from the forest floor. (Longino 2006)

Identification
In Bolton's (2000: 148) key to Neotropical Pyramica, this species keys to Strumigenys rogata, but the strongly ankylosed mesosoma is unique and immediately distinguishes this species from any other of the Glamyromyrmex-like Pyramica.

Distribution based on Regional Taxon Lists
Neotropical Region: Costa Rica.
