  • The tiny Neivamyrmex asper is a leaf-litter raider. Neivamyrmex is the species-richest army ant genus in the Neotropics, but they are very seldom observed, supposedly because they are smaller and have a more cryptic lifestyle than the other army ants. Photo by Phil Hoenle.

Jack Longino:

Face densely foveolate-granular, matte to slightly shiny; dorsum of postpetiole and first gastral tergite smooth and shining, contrasting with foveate-granular sculpture of petiole; in face view posterolateral margins of head without strongly produced triangular projections.

Biology

Jack Longino: This species occurs in Atlantic slope wet forest. At Tortuguero I found a colony inside a nasutiform termite nest. Workers were scattered throughout, but separate from the areas inhabited by termites. Brood occurred in spatially separated small batches of 10-20 larvae. In the Peñas Blancas Valley east of Monteverde, at 800m and 900m elevation, I twice observed nocturnal columns on the ground. During the ALAS expeditions on the Barva Transect, workers were obtained in a Winkler sample from the 500m site and a sweepnet sample from the 300m site.
