Description

Stephanocampta chica Aquino & Triapitsyn sp. n.

(Figs 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 F2 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; F1 longer than F2; F4 the longest funicular segment; F4–F7 decreasing in length and increasing in width; F7 as long as F3; clava almost as long as combined length of F5–F7, 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).
