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 895577: T.uniformissp. n.

Mentions: Female (Fig. 4d, e, f), 4 mm. Head (Fig. 4e): frontal vitta dark tawny, parallel sided apically equal to twice the width of the ocellar triangle, parafrontal 1.5 times as wide as frontal vitta; frontal bristles arise no lower than level of first antennal segment; proclinate orbital bristles present; antennae light black with orange present at base of first flagellomere; frontoorbital plate entirely gold; parafacial narrow, silvery to slightly gold tinged; palpi light gray at base, with orange tips, 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 remaining separate postsuturally, appearing as four distinct lines covering just over 1/2 of thorax postsuturally; three postsutural dorsocentral bristles; scutellum bearing white or yellowish pruinosity over half of its area; scutellar bristles similar to males. Wings: pale smoky grayish in color, with one bristle arising at the joint between R1 and R2+3. Abdomen (Figs 2a, 4d): pointed downward apically so as to appear strongly curved; abdominal tergites dark velvety black, with dull, grayish bands covering at least 1/2 of tergal surface; bands flat and with no distinctive mid-dorsal peaks (Fig. 2a); abdominal bands wrapping around to the underside; bright yellow bands straddling the margin between tergites ST1+2, and T3 with yellow-gray color extending up to and beyond insertion point of median marginal bristles on ST1+2; T3 and T4 possessing 1 pair of medial discal bristles, insertion point of abdominal bristles punctuated by a black outline appearing as black spots.
