Stephanocampta chica Aquino & Triapitsyn  sp. n.

( Figs 1–3View FIGURES 1 – 3)

Type material. Holotype. Argentina, Misiones, Loreto, 6.i. 1933, A.A. Ogloblin [♀, MLPA], on slide labeled: 1. “ Dicopus neotropica  (Stylo membanacea in pencil) ♀ n. sp. Loreto 6.I. 1933. A. A. O.”; 2. “ Stephanocampta  sp. ♀ det. S. Triapitsyn feb. 2014 Stephanocampta chica Aquino  y Triapitsyn Holotype ♀”.

Diagnosis. The only known female of S. chica  differs from that of S. masoni  by its shorter body (352 µm vs 455–528 µm) and in having F 2 clearly longer than wide rather than only as long as wide; it differs from S. yaosekoensis  by the relative length of the clava, as stated in the key.

Description. FEMALE. Body length including head: 352 µm. Body color brown, except legs and antennae light brown (a better description of the coloration cannot be made because the specimen is slide-mounted). Wings hyaline.

Head 0.9 × as wide as mesosoma, smooth. Antenna with scape about 2 × as long as pedicel; F 1 longer than F 2; F 4 the longest funicular segment; F 4 –F 7 decreasing in length and increasing in width; F 7 as long as F 3; clava almost as long as combined length of F 5 –F 7, with 4 mps. Mesosoma 1.2 × as long as gaster; pronotum short; mesoscutum 1.5 × as wide as long, smooth, with two short lateral setae; scutellum smooth, with two setae at anterior margin; propodeum smooth. Fore wing 9.75 × as long as wide; disc with several rows of setae in apical half; longest marginal seta 3.84 × maximum wing width. Hind wing 20.2 × as long as wide; longest marginal seta 6.3 × maximum wing width. Metasoma with petiole short, 1.7 × as long as wide; ovipositor 0.75 × length of gaster and about 0.7 × length of metatibia.

Measurements (µm). Head: 137.4; mesosoma: 168.3: 151; mesoscutum: 48.3: 73.5; gaster: 141.3; fore wing: 472: 48.4; hind wing: 432: 21.3; petiole: 27.1: 15.5; ovipositor: 106.4; metatibia: 151 (155). Antenna: scape: 71.6: 13.5; pedicel: 34.8: 19.4; F 1: 23.2: 7.7; F 2: 19.4: 5.8; F 3: 32.9: 7.7; F 4: 38.7: 9.7; F 5: 34.8: 9.7; F 6: 34.8: 9.7; F 7: 32.9: 13.5; clava: 106.4: 29.
