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. 5a, b, c), 9 mm. Head (Fig. 5b): frontal vitta dark black, tapered apically approximately 1.5X the width of the ocellar triangle, parafrontal 1/2 as wide as frontal vitta; frontal bristles arise no lower than level of pedicel; antennae black; frontoorbital plate gold turning to black apically; parafacial gold tinged in its entirety; palpi black gray; facial ridge at level of vibrissa with distinct black tinge; gena 1/6 height of head. Thorax (Fig. 5a): yellow-gold when viewed dorsally with four longitudinal black vittae, appearing fused throughout their length; appearing as two indistinct blotches covering 2/3rds of thorax postsuturally; three postsutural dorsocentral bristles; scutellum bearing yellowish pruinosity over 1/2 its total area; 3 pairs of scutellar marginal bristles; subapical scutellars widely divergent, lateral scutellars half the length of suabpicals, with these arising almost adjacent to subapical scutellars; legs black. Wings: dark smoky grayish in color, with one bristle arising at the joint between R1 and R2+3; well developped costal spine. Abdomen (Figs 1d, 5a, c): ST1+2 dark velvety black, with slight yellow extending from anterior edge of following tergite, T3, T4, and T5, with bright, yellow bands covering approximately 1/3rd of tergal surface arising at the margins of between the abdominal tergites, these bands wrapping around sides of abdomen but not the underside; bright yellow bands straddling the margin between tergites ST1+2, T3, T4 and over 50% of T5; tergal bands possessing a sharp mid-dorsal peak extending almost to margin of adjacent tergite, in both T3 and T4, but not reaching margin.
