Distribution. PALAEARCTIC: Japan, and Republic of Korea ( Sahad & Hirashima 1984).

Redescription. FEMALE (non-type specimens). Body length 700–950 µm (dry-mounted specimens). Head dark brown; often scape, pedicel, and F 1 light brown, remainder of flagellum brown but sometimes only radicle light brown and the rest of antenna brown; mesosoma light brown to brown with dark brown areas; metasoma light brown basally and brown or dark brown apically; legs yellow to light brown.

Antenna ( Fig. 12 View FIGURES 12 – 15 ) with radicle 0.35–0.36 × total length of scape, rest of scape 3.0– 3.2 × as long as wide; pedicel longer than F 1; F 1 a little shorter than F 2 and about as long as F 4 and F 6, F 2 about as long as F 3, F 5, F 7, and F 8 except when F 5 sligtly shorter when lacking mps; mps on F 5 (1 on one antenna and 0 or 1 on the other antenna), F 7 (2) and F 8 (2); clava with 8 mps, 3.1–3.2 × as long as wide, about as long as combined length of F 5 –F 8 or slightly shorter when F 5 lacks mps.

Mesosoma ( Fig. 14 View FIGURES 12 – 15 ) shorter than gaster. Propodeum ( Fig. 13 View FIGURES 12 – 15 ) with fine submedian lines. Fore wing ( Fig. 15 View FIGURES 12 – 15 ) 4.0– 4.3 × as long as wide; longest marginal seta 0.43–0.47 × maximum wing width. Fore wing disc slightly infumate throughout, mostly bare behind submarginal vein and setose behind apex of submarginal vein and beyond. Hind wing 27–29 × as long as wide; disc bare except for rows of setae along margins and a few additional setae, slightly infumate throughout; longest marginal seta 3.9–4.4 × maximum wing width.

Metasoma ( Fig. 14 View FIGURES 12 – 15 ) with petiole wider than long. Ovipositor 0.7–0.8 × length of gaster, at most barely exserted beyond its apex; ovipositor length: mesotibia length ratio 1.4–1.5: 1.

MALE (non-type specimens from Japan). Body length 630–920 µm (dry-mounted specimens). Similar to female except for normal sexually dimorphic features and the following. Scape and pedicel light brown, flagellum brown. Antenna with scape minus radicle 2.3–2.6 × as long as wide. Fore wing 4.0– 4.2 × as long as wide.

Diagnosis. Gonatocerus cincticipitis   is similar to G. aegyptiacus   and G. fuscicornis   from which it differs by the presence of mps on F 5 on at least one antenna. It also differs from G. aegyptiacus   , which also has a narrow fore wing ( Figs 4 View FIGURES 1 – 4 , 6 View FIGURES 5 – 7 ), by the discal setae on the fore wing ( Fig. 15 View FIGURES 12 – 15 ) originating behind apex of the submarginal vein (behind base of the marginal vein in G. aegyptiacus   ).

Host. Nephotettix cincticeps Uhler   (Cidadellidae) ( Sahad 1982 a [as G. sp. y], 1982 b [as G. sp. y], 1982 c; Sahad & Hirashima 1984). Biological traits of G. (Gonatocerus) cincticipitis   were reported by Sahad (1982 a) [as G. sp. y], Miura (1990 a, 1990 b), and Sahad & Hirashima (1984).
