Seven new species of Spathidexia Townsend (Diptera: Tachinidae) reared from caterpillars in Area de Conservación Guanacaste, Costa Rica.

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 892839: female, head.

Mentions: Female (Fig. 1d, e, f), head: Frontal vitta dark black, parallel sided apically equal to twice the width of the ocellar triangle, face 3 times as wide as frontal vitta; frontal bristles arise n​ o lower than level of pedicel; black hairs lining the margin of the frontal vitta; proclinate orbital bristles present; antenna black; arista black and plumose, trichia at least 4 times as long as width of base of arista, tapering at apex of arista; parafrontal entirely silver; parafacial silvery; palpi black, slightly haired along lower surface; short row of black supravibrissal hairs along facial margin. Thorax: greyish when viewed dorsally with four longitudinal black vittae, these becoming fused post-suturally, appearing as two indistinct blotches covering just more than 2/3 thorax postsuturally; three post sutural dorsocentral bristles; scutellum bearing white or yellowish pruinosity over its ½ of its entirety; legs black with silvery sheen on anterior femur. Wings: pale smoky greyish in color, vein R4+5 setose from node up to r-m, R1 bare. Abdomen: abdominal tergites dark velvety black, bright grayish bands covering at up to 1/2 of tergal surface along anterior margin of T3 and T4; yellow abdominal band wrapping around the abdomen on the posterior margin of T1+2 visible only when viewed laterally; T3, T4 and T5 possessing medial marginal bristles. Lateral marginal bristles on T1+2. Small black 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.
