Abstract
Potamanaxas louisghilli Grishin, sp. nov. is described from Area de Conservación Guanacaste (ACG) in northwestern Costa Rica. Superficially, this species resembles several other Potamanaxas taxa with entire pale discal bands on the wings, but is distinguished from them by a row of faint postdiscal forewing spots (not streaks), terminally elongated genitalic valvae, and distinctive COI DNA barcodes. Found feeding on rain forest epiphytic Cavendishia axillaris and Psammisia ramiflora, the new species is likely to be host-specific to rain forest epiphytic Ericaceae, which are the food plants of all other known species of ACG Potamanaxas as well.
