Biology:

Inhabits lowland to lower montane wet forest; nests in rotten twigs or small pieces of rotten wood on the forest floor; predaceous on small arthropods.

 

Identification:

Mandibles much longer than head, with multiple preapical teeth or denticles; face largely shiny.

Comments:

A distinctive dark form of A. teledectus occurs on the Barva transect in Costa Rica. Specimens I have examined from La Selva Biological Station (50-100m elevation) and all specimens from north of Costa Rica are red brown, with feeble fossae on the gena, and with relatively longer propodeal spines. Collections from 300-600m elevation on the Barva transect, just above La Selva, are darker brown, with coarse fossae on the gena, and short propodeal spines.
