A new species of Trismegistomya Reinhard (Diptera: Tachinidae) from Area de Conservación Guanacaste in northwestern Costa Rica

Abstract

Background The New World genus Trismegistomya Reinhard, 1967b (Diptera: Tachinidae) previously included only the type species Trismegistomya pumilis (Reinhard, 1967a) from Arizona, U.S.A. New information We describe a new species of Trismegistomya, Trismegistomya jimoharai Fleming & Wood sp. n., from Area de Conservación Guanacaste (ACG) in northwestern Costa Rica, reared from wild-caught caterpillars of Melipotis januaris (Guenée, 1852) (Lepidoptera: Erebidae). Our study provides a concise description of the new species using morphology, life history, molecular data and photographic documentation. In addition to the new species description, we provide a redescription of the genus, as well as of its type species Trismegistomya pumilis.
