Darwin wasps of the genus Seticornuta Morley, 1913 (Ichneumonidae: Metopiinae) in the Neotropical region, with a key to species Alvarado, Mabel European Journal of Taxonomy 2022 2022-10-10 839 149 175 Alvarado, 2022 Alvarado 2022 [617,873,601,627] Insecta Ichneumonidae Seticornuta Animalia Hymenoptera 11 160 Arthropoda species curupira sp. nov.   urn:lsid:zoobank.org:act: 52C58F37-4DD0-4171-8484-F611DB5A7601   Figs 4, 10I, 11A    Diagnosis This species can be recognized by this combination of features: pronotum and mesoscutum tawny, and metapleuron rectangular.    Etymology The specific ‘curupira’ is in reference to the mythological creature that lives in Brazilian forests. It is treated as a noun in apposition.    Material examined   Holotype   BRAZIL• ♀; “ Nova Teutonia Santa Caterina  Nov. 1970Brazil Fritz Plaumann”; USUC.   Paratypes  BRAZIL•  1 ♂; “ BRAZIL: Nova Teutonia27°11′B 52°23′L.  15.iii.1937. Flitz Plaumann.

The paratypesdiffer from the holotypein the following: fore wing length 6.5–7.0 mm; lateral ocellus separated from compound eye by 0.7–0.8 × ocellar diameter; distance between ocelli 1.3–1.5 × its own maximum diameter; ratio of length from second to fourth flagellomeres: 1.0–1.1:1.0:1.0, subapical flagellomere elongate, 1.3–1.4 × as long as centrally wide; fore wing with Cu1a between Cu1b and 2mcu 1.4–1.5 × as long as Cu1 between Rs&M and 1m-cu; metasomal tergite I 0.9 × as long as posteriorly wide, lateromedian carinae extending 0.5–0.7 × length of tergite; laterotergite II 0.5–0.6 × as long as wide; laterotergite III 0.7 × as long as wide.  Male The paratypesdiffer from the holotypein the following: fore wing length 6.2–6.3 mm; malar space 0.6 × as long as basal mandibular width; lateral ocellus separated from compound eye by 0.6 × ocellar diameter; distance between ocelli 1.2–1.5 × its own maximum diameter; gena, on lateral view 0.8 × as long as compound eyes; antenna with 31 flagellomeres, ratio of length from second to fourth flagellomeres: 1.4–1.5:1.2–1.5:1.2–1.4, subapical flagellomere elongate, 1.3–1.4 × as long as centrally wide; fore wing with Cu1a between Cu1b and 2m-cu 1.3–1.5 × as long as Cu1 between Rs&M and 1m-cu; laterotergite II 0.6 × as long as wide. There is variation in the coloration compared to females: procoxa and meso- and metatibia entirely light yellow.    Remark This species was collected in the Brazilian state of Santa Catarina( Fig. 11A), at the same locality as  S. flava sp. nov. 3924437311 [189,1230,1113,1139] 1970-11 USUC Fritz Plaumann Brazil Nova Teutonia Nova Teutonia 11 160 1 1 Santa Caterina holotype 3924437317 1937-03-15 NHMUK Flitz Plaumann Brazil -27.183332 Nova Teutonia -52.383335 Nova Teutonia 11 160 1 1 paratype 3924437304 1948-08-09 CNC Fritz Plaumann Brazil 400 -27.183332 Nova Teutonia 1238 -52.383335 Nova Teutonia 11 160 CNC493240 1 1 paratype 3924437321 1968-01 CNC Fritz Plaumann Brazil 400 -27.183332 Nova Teutonia 1238 -52.383335 Nova Teutonia 11 160 CNC493239 1 1 paratype 3924437318 1971-01 USUC Fritz Plaumann Brazil Nova Teutonia Nova Teutonia 11 160 1 1 Santa Caterina paratype 3924437307 [438,1161,1354,1381] 1942-11-01 USUC F.
