Fleming AJ, Wood DM, Janzen D, Hallwachs W, Smith MA - Biodivers Data J (2015)

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 893722: male lateral.

Mentions: Male (Fig. 3a, b, c), head: Frontal vitta dark black, narrowed apically to less than the width of the ocellar triangle, face 4 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 with dark blotches on the apical outer surface; arista brown 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 gold to just below lower proclinate orbital bristles, then transitioning to silver with minute hairs over its entire surface; parafacial silver; palpi orange; short row of yellow supravibrissal hairs along facial margin. Thorax: greyish-gold when viewed dorsally with four faintly visible longitudinal grey vittae, these becoming slightly more visible post-suturally, appearing broken at thoracic suture; three post sutural dorsocentral bristles; scutellum concolorous with thorax over its entirety, thorax silver grey when viewed laterally; anterior femur bearing silvery pruinosity, anterior tibiae slightly yellow and hirsute with black tarsi, 2nd and 3rd pair of legs entirely black. Wings: pale smoky greyish in color, vein R4+5 setose along its entirety; vein R1 bare. Abdomen: abdominal tergites dark black medially, with bright grey band covering 1/3rd or more of tergal surface arising at the anterior 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 up to half of T4, these blotches do not continue ventrally to the tip of the abdomen; tergites T3, T4 and T5 possessing medial marginal bristles. Lateral marginal bristles on T1+2. Medium length yellow hairs visible over entire body, in particular visible extending from underside of T1+2.
