Redescription. FEMALE (specimens from the Neotropical region). Body length 630–920 µm. Body generally golden, yellowish-brown, or light brown with brown markings; antenna, particularly flagellum, darker (brown to dark brown) except radicle yellowish or light brown; legs yellowish to light brown.
Antenna (Fig. 62) with radicle 3.2–3.3x as long as wide, about 0.3x total length of scape, rest of scape 3.5–3.9x as long as wide, faintly striate; pedicel notably longer than F1; F1 about as long as F2 and slightly shorter than F3, F4 a little longer than F3 and shorter than following funicle segments, F5–F8 subequal in length; F1–F4 without mps, F5 and F6 almost always with 1 mps (F6 rarely without mps on one antenna in small specimens), F7 and F8 with 2 mps; clava with 6 mps, 3.1–3.5x as long as wide, about as long as combined length of F6–F8.
Mesosoma (Fig. 64). Mesoscutum, scutellum, and axillae with weak sculpture. Propodeum (Fig. 63) with faint submedian lines, the distance between them shorter basally than distally. Forewing (Fig. 65) 4.6–5.4x as long as wide; longest marginal seta 0.56–0.62x maximum wing width. Forewing disc with a slight, uniform brownish tinge, almost bare behind submarginal vein except for at most a few setae behind its apex, setose behind marginal vein and elsewhere. Hind wing narrow, 31–35x as long as wide; disc with a row of setae along each margin and a few scattered setae, slightly infumate; longest marginal seta 4.3–4.8x maximum wing width.
Metasoma (Fig. 64) a little longer than mesosoma. Petiole about 1.5x as wide as long. Ovipositor about 0.7x length of gaster, not exserted beyond its apex; ovipositor length: mesotibia length ratio about 1.0:1. External plate of ovipositor with 2 or 3 distal setae.
MALE. Unknown in the Neotropical region. See Baquero & Jordana (2003) for the description of the male based on specimens from Navarre, Spain.
Diagnosis. Gonatocerus (Lymaenon) chrysis is mostly a light-colored species with brown markings on the body, also characterized by the female antenna (Fig. 62) with 1 mps almost always on F5 and F6 (rarely without mps on one antenna in small specimens), 2 mps on F7 and F8, and 6 mps on the clava; a narrow (4.4– 5.4x as long as wide) forewing (Fig. 65) with relatively long marginal setae (longest marginal seta 0.5–0.7x maximum forewing width); and a short ovipositor (ovipositor length: mesotibia length ratio 0.9–1.2:1). To facilitate recognition of this species, here we also provide illustrations of the antenna (Fig. 66), forewing (Fig. 67), and genitalia (Fig. 68) of the male (specimen from the Palaearctic region).
Distribution. NEOTROPICAL*: Argentina *, Brazil *, and Chile *. NEARCTIC*: Bermuda * (Bermuda Islands, UK), Canada *, and USA *. PALAEARCTIC: Belgium, Bulgaria (Donev 1987, 1990, 2005), Finland, France *, Greece (including Crete) (Donev 1988c, 2003, 2005), Romania (Boţoc 1960), Russia *, Spain (Baquero & Jordana 2003), Sweden (Noyes 2003), Turkey (Donev 2001), and UK: England (Graham 1973; Matthews 1986), Scotland, and Wales (Matthews 1986).
This common Palaearctic species is for the first time recorded here from the New World.
Hosts. Unknown.
