Three new species of Trigonospila Pokorny (Diptera: Tachinidae), from Area de Conservación Guanacaste, northwestern Costa Rica, with a key for their identification.
Bottom Line: All species published as new, are known to be previously undescribed as a result of careful study of the genus by DMW.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.

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.

Mentions: Male (Fig. 4a, b, c), 9 mm. Head (Fig. 4b): frontal vitta dark black, slightly tapered apically to twice the width of the ocellar triangle, parafrontal 1/2 as wide as frontal vitta; frontal bristles arise no lower than level of first antennal segment; antennae black; frontoorbital plate silvery-gold turning to black apically; parafacial silvery to slightly gold tinged; palpi black gray; gena 1/8 height of head. Thorax (Fig. 4a): yellow when viewed dorsally with four longitudinal black vittae, these appear fused throughout their length with only slight separation apparent; appearing as two indistinct blotches covering 2/3rds of thorax postsuturally; three postsutural dorsocentral bristles; scutellum bearing white or yellowish pruinosity only at apex (occupying less than 1/5th of total area); 3 pairs of scutellar marginal bristles; subapical scutellars widely divergent, lateral scutellars reduced, almost half the length of the subapicals, these closer to apex, than to basal scutellars; legs black. Wings: pale smoky grayish in color, with one bristle arising at the joint between R1 and R2+3. Abdomen (Figs 1a, 4a): abdominal tergites dark velvety black, with bright, yellow bands covering less than 1/3rd of tergal surface arising at the margins of between the abdominal tergites, these bands not wrapping around to the underside; bright yellow bands straddling the margin between tergites ST1+2, T3, and the anterior margin of T4; tergal bands not possessing a sharp mid-dorsal peak rather appearing flat.
