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 895580: T.josemariamoragaisp. n.

Mentions: Female (Fig. 3d, e, f), 6.7 mm. Head: frontal vitta dark black, parallel sided apically equal to twice the width of the ocellar triangle, parafrontal equal in width to the frontal vitta; frontal bristles arise no lower than level of first antennal segment; proclinate orbital bristles present; antennae black; frontoorbital plate almost entirely gold; parafacial silvery to slightly gold tinged; palpi orange, slightly haired along upper surface; gena 1/10 height of head. Thorax (Fig. 3d): yellow when viewed dorsally with four longitudinal black vittae, these becoming fused postsuturally, appearing as two indistinct blotches covering just over 1/2 of thorax postsuturally; 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 still reduced but more pronounced than in males, almost half the length of the subapicals, these closer to apex, than to basal scutellars; legs black with silvery sheen. Wings: pale smoky grayish in color, with one bristle arising at the joint between R1 and R2+3. Abdomen (Figs 2d, 3f): pointed downward apically so as to appear strongly curved; ST1+2, dark velvety black with very slight infiltration of dull, grayish or bright yellow bands from next segment along posterior margin, T3, T4, and T5 with bands covering up to 1/2 of tergal surface; bands peaked dorsocentrally creating an apparent dorsocentral stripe extending the length of the abdomen (Fig. 2d); abdominal bands wrapping around to the underside; bright yellow bands straddling the margin between tergites ST1+2, T3, with yellow extending up to but not above median marginal bristles on ST1+2 and the anterior margin of T4; T3 and T4 possessing 1 pair of medial discal bristles, insertion point of abdominal bristles punctuated by a black outline appearing as black spots; when viewed dorsally abdomen appearing to have 4 black rounded triangles surrounded by yellow, with 4 black dots between them.
