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.

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.

Figure 895587: male frontal

Mentions: Male (Fig. 3a, b, c), 8.8 mm. Head (Fig. 3b): frontal vitta dark black, narrowed apically to equal width of the ocellar triangle, parafrontal (as measured between the inner margin of the eye and the frons, at the apex of the lunule) subequal in with to the frontal vitta; frontal bristles arise no lower than level of first antennal segment; antennae black; frontoorbital plate entirely gold; parafacial silvery to slightly gold tinged; palpi black gray; gena 1/8 height of head. Thorax (Fig. 3a): yellow when viewed dorsally with four longitudinal black vittae, these becoming fused postsuturally, appearing as two indistinct blotches covering 2/3rds of thorax post-suturally; three postsutural dorsocentral bristles; scutellum bearing white or yellowish pruinosity over its entirety (occupying 1/2 or more of total area); 3 pairs of scutellar marginal bristles; subapical scutellars widely divergent, lateral scutellars hairlike, 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 1c, 3a): 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, yellow bands covering 1/3rd or more of tergal surface arising at the margins of between the abdominal tergites, these bands wrapping around to the underside; bright yellow bands straddling the margin between tergites T1+2, T3, and the anterior margin of T4; tergal bands possessing a sharp mid-dorsal peak figuring prominently on both T3 and T4, these extending 1/2 way across T3, and to the margin of T4; T3 and T4 possessing 2 pairs of medial discal bristles, insertion point of abdominal bristles punctuated by a black outline appearing as black spots.
