Taxonomic history

See also: Bolton, 2000: 17.


Neotropical Region: Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Nicaragua, Panama, Peru

Distribution Notes:

Colombia to Guatemala. Costa Rica: Atlantic lowlands.



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.



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


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.
