This revision is part of a continuing series of taxonomic work aimed at the description of new taxa and the redescription of known taxa of the Tachinidae of Area de Conservación Guanacaste in northwestern Costa Rica. Here we describe 33 new species in the genusBelvosiaRobineau-Desvoidy, 1830 (Diptera: Tachinidae). All species described here were reared from this ongoing inventory of wild-caught caterpillars spanning a variety of families (Lepidoptera: Erebidae, Eupterotidae, Noctuidae, Notodontidae, Saturniidae, and Sphingidae). We provide a morphological description of each species with limited information on life history, molecular data, and photographic documentation. In addition to the new species, the authors provide a redescription of the genusBelvosia, as well as provide a key to the identification of the species present in the Meso- and North-American fauna.

Belvosia canalisAldrich, 1928 is reared and recorded from the inventory; new information relative to host is provided and the species is rediscribed.

The following are proposed by Fleming & Woodley as new synonyms ofBelvosiaRobineau-Desvoidy, 1830:BrachybelvosiaTownsend, 1927syn. n.,BelvosiomimopsTownsend, 1935syn. n.

The following three new combinations are proposed as a result of the new synonymies:Belvosia brasilensis(Townsend, 1927),comb. n.; andBelvosia barbiellinii(Townsend, 1935),comb. n.
