Abstract
We describe three new species of Trigonospila Pokorny (Tachinidae: Blondeliini) from Area de Conservación Guanacaste (ACG), northwestern Costa Rica. All were reared from various species of ACG caterpillars during an ongoing inventory of caterpillars, their food plants and their parasitoids in dry forest, rain forest and cloud forest. By coupling morphology, photographic documentation, life history and molecular data, we provide a clear and concise description of each species. All species published as new, are known to be previously undescribed as a result of careful study of the genus by DMW. This study builds on the current knowledge of the genus by adding three new species to the current 7 described in the New World. Trigonospila edwinbermudezi sp. n., Trigonospila uniformis sp. n., and Trigonospila josemariamoragai sp. n. are all authored and described as new by Fleming and Wood, with a key to their identification. The authors also offer a new record and description of the previously unknown male of Trigonospila panamensis (Townsend), reared from ACG caterpillars.
Highlights
The tachinid genus Trigonospila Pokorny 1886, is a small cosmopolitan genus in the tribe Blondeliini of the Exoristinae (Diptera, Tachinidae) (Wood 1985, O'Hara and Wood 2004)

Wood (1985) provided a concise diagnosis of the tribe based on Mesnil's work: 1) prosternum setose, 2) first postsutural supraalar bristle, smaller than first postsutural dorsocentral, 3) bend of wing vein M, rounded and obtuse angled, 4) subapical scutellar bristles, long stout and divergent (Wood suggested this character may be variable with respect to tribal placement), and 5) wing vein R4+5 ending at or near the wing margin (Wood 1985)
Summary
The tachinid genus Trigonospila Pokorny 1886, is a small cosmopolitan genus in the tribe Blondeliini of the Exoristinae (Diptera, Tachinidae) (Wood 1985, O'Hara and Wood 2004).
