“We have little doubt it is rightly referred to this species,” wrote Godman and Salvin (1893: 262) about their only Panamanian specimen, a female from Calobre, in order to treat the South American Jemadia hewitsonii (Mabille, 1878) in their “Biologia Centrali-Americana. Insecta. Lepidoptera—Rhopalocera.” Half a century later, Evans included her in a type series of the newly described subspecies J. hewitsonii pater Evans, 1951, which after 50 more years Burns elevated to species status. This female is neither J. hewitsonii nor J. pater, but a new species, possibly closest to South American Jemadia ovid Evans, 1951, new status. The new Central American Jemadia, repeatedly reared in the Caribbean rain forest of Costa Rica's Area de Conservación Guanacaste, is described here as Jemadia suekentonmiller Grishin, sp. nov.; and its facies, genitalia, and DNA barcodes are closely compared with those of various congeners. The twice-misplaced female is a paratype of J. suekentonmiller and is still the only known specimen from Panama.
