Strumigenys infidelis

Known from a cloud forest and plantain planting.

Identification
Bolton (2000) - A member of the Strumigenys louisianae-group. Material of this species is sparse. S. infidelis has the same preapical dentition and the deep narrow postbuccal groove seen in Strumigenys louisianae, but lacks the flagellate humeral hairs of that species. For this reason I have revived infidelis from the synonymy of louisianae where Brown (1962b) left it.

Distribution based on Regional Taxon Lists
Neotropical Region: Argentina, Bolivia, Brazil, Venezuela.
