All ACG specimens were reared from wild-caught Lepidoptera larvae (Lepidoptera: Erebidae, Nolidae). We provide a concise description of both species using morphology, life history, molecular data, and photographic documentation. The new species is authored and described by Fleming and Wood.<h4>New information</h4>Phosocephala alexanderi sp. n.Biodiversity data journale7863https://www.ebi.ac.uk/biostudies/studies/S-EPMC4867709biostudies-literatureA new species of Phosocephala Townsend, 1908 (Diptera: Tachinidae) from Area de Conservacion Guanacaste in northwestern Costa Rica.PMC4867709Janzen DHHallwachs WSmith MAFleming AJWood DMDapkey TfalseA new species of Phosocephala Townsend, 1908 (Diptera: Tachinidae) from Area de Conservacion Guanacaste in northwestern Costa Rica.<h4>Background</h4>We describe a new species of Phosocephala Townsend, and provide a new collection record, and description of the previously unknown male, of Phosocephala metallica Townsend, from Area de Conservación Guanacaste (ACG), northwestern Costa Rica.
