Neivamyrmex compressinodis

This species is only known from queens and/or workers and has yet to be associated with males.

Identification
Jack Longino:

Face smooth and shining; juncture of dorsal and posterior faces of propodeum forming sharp right angle; postpetiole in dorsal view relatively thin; eye without distinct convex cornea, reduced to yellow spot below cuticle or absent.

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

Biology
Jack Longino: The type specimens were collected at "Port Limón."

I know this species from one collection. The location and habitat was 25 year old second growth forest at El Plastico, a 550m elevation site on the Atlantic slope near La Selva. Workers were in a Winkler sample of sifted leaf litter from the forest floor.
