The first records of Bycrea villosa Pascoe (Coleoptera : Tenebrionidae) in the United States, Central America and Colombia and notes on its association with leaf-cutting ants

摘要

The first records of Bycrea villosa Pascoe (Coleoptera: Tenebrionidae; Opatrinae) outside Mexico are reported, including recent collections from Arizona, USA, and specimens from Colombia, Costa Rica, El Salvador and Guatemala. The beetle is of interest because of its association with the nests of leaf-cutter ants (Hymenoptera: Formicidae), specifically Atta mexicana (F. Smith) and probably other Atta species that have above-ground refuse dumps. A diagnosis and images of the beetle adult and larva are included.
