Adelomyrmex microps occurs in lowland rainforest and is extremely rare. It is currently known from 13 specimens. Ten of those are from La Selva Biological Station, from eight different Berlese and MiniWinkler samples (far less than 1% of samples). The LLAMA project collected a specimen in a MiniWinkler sample from a 280 m elevation site near La Ceiba, Honduras, and two in MiniWinkler samples from 310 m elevation on Cerro Saslaya, Nicaragua.

Adelomyrmex microps is a lowland version of Adelomyrmex laevigatus, differing in lighter color, less robust sculpture, and denser, longer pilosity. Additional material shows that the key characters used in Fernández and Mackay (2003) will not separate the species: both usually have smooth shiny areas on the side of the pronotum and stout hypostomal teeth. Ommatidial count is variable. One specimen from Costa Rica (La Selva Biological Station), currently considered a nanitic or aberration, has short, sparse, completely appressed pilosity on the face and gaster, and the overall sculpture is feeble. The specimen from Honduras has several longitudinal rugae on the side of the pronotum instead of a smooth patch. (Longino 2012)
