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 893744: male lateral.

Mentions: Male (Fig. 5a, b, c), 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 quarter of first flagellomere and pedicel, darkening apically; arista black and plumose, trichia at least 2 times as long as width of base of arista, tapering at apex of arista; proclinate orbital bristles present; parafrontal almost entirely silver, gold only along apex surrounding ocellar triangle, with minute hairs over its entire surface; parafacial silver; palpi orange; lacking short row of yellow supravibrissal hairs along facial margin. Thorax: dull greyish-gold when viewed dorsally with two faint smoky longitudinal grey bands; three post sutural dorsocentral bristles; scutellum concolorous with thorax over its entirety, thorax silver grey when viewed laterally; anterior femur bearing silvery pruinosity; anterior pair of legs with femur bearing silvery pruinosity, tibiae dark brownish yellow and hirsute with black tarsi, 2nd and 3rd pair of legs black entirely; claws of male shorter than apical tarsal segment. Wings: pale smoky greyish in color, Vein R4+5 setose to just past crossvein r-m; vein R1 haired along its entirety. Abdomen: abdominal tergites dark shiny black medially, with bright grey band covering 1/5th or more of tergal surface arising along 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 anterior half of T4; median marginal bristles on T3, T4 and T5. Lateral marginal bristles on T1+2. Medium length yellow hairs visible over entire body, in particular visible extending from underside of T1+2.
