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.
