The few Costa Rican records of this species are from cloud forest habitats. Workers have been collected in Winkler samples of sifted leaf litter from the forest floor.

Identification ( anglais )

fourni par Antweb
In Central America, several species of Acropyga have mandibles that are narrow and strap-shaped, with only 3 teeth on the relatively short masticatory margin. Queens may occasionally have 4 teeth, but the mandible is still narrow and strap-shaped. LaPolla (2004) distinguished these species mainly on male genitalia. Workers are not easily distinguished.

At La Selva Biological Station in Costa Rica, A. exsanguis and A. keira co-occur. The workers of A. exsanguis are scruffier, with somewhat more abundant dorsal pilosity. The males are more distinct, with males of A. keira having larger apices of the penis valves. A few worker collections from higher elevations above La Selva and in Monteverde are larger than the typical La Selva A. exsanguis and are tentatively identified as A. goeldii. LaPolla also described A. palaga, with workers indistinguishable from A. goeldii, based on a collection from Estrella Valley in the Atlantic lowlands and a collection from Alajuela.

North of Costa Rica, a few collections have associated males, and these more or less match La Selva A. exsanguis. Longino uses A. exsanguis as the default identification for A. exsanguis-like material from Nicaragua to Mexico, but it is likely that multiple cryptic species occur.
