Comments:

The species A. lentus Mann is from Honduras and differentiated from A. ocellatus by coarser, more confluent fossae on the posterior face. Brown and Kempf speculated that this could be just a sculptural variant of A. ocellatus. Current material shows a somewhat abrupt transition between two forms. In Costa Rica, the Atlantic lowlands of Nicaragua, extending to La Mosquitia in eastern Honduras, workers are lighter red brown, the fossae are a bit more separated on the face, and the dorsal mesosoma is more lightly sculptured. Just across the Sierra de Agalta, in the north coastal region of Honduras, extending through eastern Guatemala to the eastern lowlands of Chiapas, workers are darker red, with more closely-spaced fossae on the face, and with dorsal mesosoma more heavily sculptured. This latter form matches A. lentus. However, DNA barcoding does not differentiate the two forms. Given the lack of sympatry and no evidence of genetic differentiation, I consider A. lentus to be a junior synonym of A. ocellatus.
