Cryptic species within cryptic moths: new species of Dunama Schaus (Notodontidae, Nystaleinae) in Costa Rica

Based on almost 1,700 recently reared and wild-collected specimens, the genus Dunama Schaus (Notodontidae, Nystaelinae) in Costa Rica is reviewed. Eight species are recorded of which seven are newly described: Dunama jessiehillae Chacón, Dunama jessiebarronae Chacón, D. janewaldronae Chacón, D. jessiebancroftae Chacón, D. janecoxae Chacón, D. biosise Chacón, D. indereci Chacón. Dunama angulinea Schaus is redescribed and associated with its correct genitalia. D. tuna (Schaus), previously listed as ocurring in Costa Rica, is restricted to Colombia. Most species are described through their distinctive CO1 barcodes, genitalia and life histories. Dunama adults and caterpillars, their foodplants, and their parasites in Area de Conservación Guanacaste (ACG) in northwestern Costa Rica are described where known. Many life history stages are illustrated.
