    Americas: Costa Rica, Ecuador, Guatemala, Honduras, Mexico, Nicaragua
  Biogeographic regions (According to curated Bioregion/Taxon lists):
    Neotropical

Distribution Notes:

Costa Rica (type locality), Mexico (Fernandez and MacKay 2003, Fernandez 2003). Costa Rica: rainforests of Atlantic and southern Pacific lowlands, below 500m elevation.

Biology:

Natural History:

Inhabits forest floor litter. Known only from Winkler samples.

Notes:

Fernandez (2003) lists among the paratypes of this species a collection of mine, JTL2339-s, a Winkler sample from Estacion Cacao at 1500m. My records of material from this collection include only Adelomyrmex laevigatus and tristani. This may be an error in the publication. All other records suggest A. longinoi is a lowland species, and it would be unlikely to find it at the 1500m Cacao site.
