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, previously unknown from the original description of T.panamensisTownsend 1919 (Fig. 6a, b, c), 8 mm. Head (Fig. 6b): frontal vitta dark black, narrowly tapered apically to just slightly greater than the width of the ocellar triangle, parafrontal 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 with orange tips; gena 1/10 height of head. Thorax (Fig. 6a): yellow when viewed dorsally with four longitudinal black vittae, these appear to be distinct and separate throughout their length; dorsal lines remain separate post suturally covering 2/3rds of thorax; three postsutural dorsocentral bristles; scutellum bearing white or yellowish pruinosity occupying ½ or more 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 1b, 6a): ST1+2, dark velvety black with very slight infiltration of yellow band from next tergite, along its posterior margin, T3, T4, and T5, all with bright, narrow yellow bands covering 1/3rd or more of tergal surface, these bands wrapping around to underside of tergites; 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, instead the margins of the bands appear as jagged on both T3 and T4; yellow bands wrapping around to the underside of the abdomen.
