expand Abstract

A new genus and species of within the tribe Eryciini are described from the Area de Conservación Guanacaste (ACG) in north-western Costa Rica. Specimens were reared from wild-caught caterpillars collected during an ongoing biodiversity inventory within the ACG. An integrative taxonomic approach was used to characterise the new taxa, incorporating morphological analysis, life history data and DNA barcodes, supported by high-resolution photographs. Furthermore, two new combinations are proposed and the associated species are re-described. A lectotype is designated for Exorista loxostegae (Reinhard, 1922) and an identification key to the species of the new genus is provided. The description of the new genus Santarosamyia Fleming and Wood, 2024 gen. nov. along with the new species: Santarosamyia woodorum Fleming & Wood sp. nov. are provided. The following new combinations are proposed: Nilea erecta (Coquillett, 1902) as Santarosamyia erecta (Coquillett, 1902) comb. nov. ; Nilea uniplilum (Aldrich & Webber, 1924) as Santarosamyia unipilum (Aldrich & Webber, 1924) comb. nov. A lectotype is designated for Exorista loxostegae (Reinhard, 1922). Tachinidae, Diptera, Costa Rica, CO1, Parasitoid, Guanacaste
