Bottom Line: All are known to be previously undescribed as a result of a comprehensive study of the genus by DMW.Minthodexiopsis Townsend is proposed by Wood as a new synonym of Spathidexia.A new combination proposed by Wood as a result of the new synonymy is S.flavicornis (Brauer & Bergenstamm) comb. n.

ABSTRACT
We describe seven new species of Spathidexia (Diptera: Tachinidae) reared 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. By coupling morphology, photographic documentation, life history and molecular data, we provide a clear and concise description of each species. All are known to be previously undescribed as a result of a comprehensive study of the genus by DMW. Spathidexiaatripalpus sp. n., Spathidexiajuanvialesi sp. n., Spathidexiamarioburgosi sp. n., Spathidexialuisrobertogallegosi sp. n., Spathidexialuteola sp. n., Spathidexiahernanrodriguezi sp. n. and Spathidexiaaurantiaca sp. n. are all authored and described by Fleming and Wood. Minthodexiopsis Townsend is proposed by Wood as a new synonym of Spathidexia. A new combination proposed by Wood as a result of the new synonymy is S.flavicornis (Brauer & Bergenstamm) comb. n.

Figure 893735: female head

Mentions: Female (Fig. 4d, e, f), head: Frontal vitta dark black, narrowed apically to less than the width of the ocellar triangle, face 8 times as wide as frontal vitta; frontal bristles arise no lower than level of pedicel; yellow hairs lining the margin of the frontal vitta; antenna orange along upper half, first flagellomere darkening apically; arista black and plumose, trichia at least 4 times as long as width of base of arista, tapering at apex of arista; proclinate orbital bristles present; parafrontal almost entirely silver, gold along apex surrounding ocellar triangle and following margin of frontal vitta, sparse minute hairs over upper half of fronto-orbital plate; parafacial silver; palpi orange; short row of yellow supravibrissal hairs along facial margin. Thorax: greyish-gold when viewed dorsally with four longitudinal grey vittae, these only slightly visible post-suturally, appearing broken at thoracic suture; three post sutural dorsocentral bristles; scutellum bearing white or yellowish pruinosity over its entirety; legs anterior femur bearing silvery pruinosity, anterior pair of legs with tibiae yellow and hirsute with black tarsi, 2nd and 3rd pair of legs black entirely. Wings: pale smoky greyish in color, vein R4+5 setose up to crossvein c-m; vein R1 bare. Abdomen: abdominal tergites dark shiny black medially, with bright grey band covering 1/3rd or more of tergal surface arising at the margins of abdominal tergites T3, T4 and T5, these bands wrapping around to the underside. Bright yellow blotches appear along tergites T1+2, T3 and the anterior margin of T4; T3, T4 and T5 possessing medial marginal bristles, ovipositor concealed within segment 5. Lateral marginal bristles on T1+2. Small yellow hairs visible over entire body, not as hirsute as males but still present, in particular visible extending from anepimeron, and from underside of T1+2.
