Distribution. PALAEARCTIC: Austria *, Bulgaria ( Donev 2005 [as G. minor   ], China *, Denmark *, Egypt, France *, Greece ( Donev 2003, 2005) [as G. minor   ], Hungary *, Italy *, Japan ( Sahad 1982 c [as G. miurai   ]; Sahad & Hirashima 1984 [as G. miurai   and G. sulphuripes   ]), Kyrgyzstan *, Republic of Korea ( Sahad & Hirashima 1984) [as G. miurai   ], Mongolia *, Russia *, Spain ( Baquero & Jordana 2003) [as G. minor   ], and UK ( England) ( Matthews 1986) [as G. minor   ]. AFROTROPICAL*: Republic of South Africa *, and United Arab Emirates *. AUSTRALASIA*: Australia *. OCEANIA: American Samoa *, Fiji *, Northern Mariana Islands ( Doutt 1955) [as G. saipanensis   ]. ORIENTAL: India ( Zeya & Hayat 1995; Zeya & Khan 2011) [as G. tarae   ], Nepal *, Pakistan *, and Thailand *. NEARCTIC*: USA *.

Redescription. FEMALE (non-type specimens from the Palaearctic region). Body length 630–960 µm (dry-mounted specimens). Head dark brown; scape, pedicel, and usually F 1 –F 4 light brown, F 5 –F 8 and clava brown; mesosoma and metasoma normally mostly yellow or light brown with brown markings on mesoscutum, axillae, scutellum, propodeum, and apical gastral terga, but sometimes mesosoma mostly brown with yellow or light brown areas and apical gastral terga brown to dark brown; legs mostly light brown.

Antenna ( Fig. 1 View FIGURES 1 – 4 ) with radicle 0.32–0.4 × total length of scape, rest of scape 2.1–3.1 × as long as wide; pedicel longer than F 1; F 2 about as long as F 3 and often F 8 (the longest funicle segments), F 4 the shortest funicle segment, F 7 about as long as F 8 when bearing mps but notably shorter when lacking mps; F 1 –F 6 withouts mps, F 7 with 1 or 2 mps but sometimes without mps, F 8 with 2 mps; clava with 8 mps, 3.2–4.1 × as long as wide, about as long as combined length of F 5 –F 8 or slightly shorter when F 7 lacks mps.

Mesosoma ( Fig. 3 View FIGURES 1 – 4 ) a little shorter than gaster. Propodeum ( Fig. 2 View FIGURES 1 – 4 ) with submedian lines often hardly visible. Fore wing ( Fig. 4 View FIGURES 1 – 4 ) 3.8–4.4 × as long as wide; longest marginal seta 0.38–0.52 × maximum wing width. Fore wing disc slightly infumate throughout, bare behind submarginal vein, setose behind and beyond marginal vein although occasionally setae sparse between marginal vein and cubital row of setae. Hind wing 26–30 × as long as wide; disc bare except for rows of setae along margins and a few additional setae, slightly infumate throughout; longest marginal seta 3.3–4.3 × maximum wing width.

Metasoma ( Fig. 4 View FIGURES 1 – 4 ). Petiole wider than long. Ovipositor 0.8–0.9 × 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 the Palaearctic region, previously unknown from Europe). Body length 630–800 µm (dry-mounted specimens). Similar to female except for normal sexually dimorphic features and the following. Coloration of body and legs usually at least a little darker than in female; scape and pedicel light brown, flagellum brown. Antenna ( Fig. 5 View FIGURES 5 – 7 ) with scape minus radicle about 1.8 × as long as wide. Fore wing ( Fig. 6 View FIGURES 5 – 7 ) 4.4– 4.7 × as long as wide. Genitalia as in Fig. 7 View FIGURES 5 – 7 .

Diagnosis. Gonatocerus aegyptiacus   may be difficult to distinguish from G. fuscicornis   (especially the darker-colored specimens and females in which F 7 of the antenna bears 2 mps) but in the latter species the discal setae originate behind about middle of the submarginal vein ( Figs 20 View FIGURES 19, 20 , 24 View FIGURES 21 – 24 , 26 View FIGURES 25 – 27 ) whereas in the former the fore wing disc is bare behind the entire submarginal vein ( Figs 4 View FIGURES 1 – 4 , 6 View FIGURES 5 – 7 ). In most specimens from Egypt identified by W. Soyka as G. aegyptiacus   , and also in some other, small, specimens from Europe F 7 of the female antenna either lacks mps or bears just 1 mps.

Gonatocerus aegyptiacus   is also very similar to G. (Gonatocerus) californicus Girault   , known from the New World and the Hawaiian Islands (Triapitsyn et al. 2010; Luft Albarracin & Triapitsyn 2012), and G. (Gonatocerus) utahensis Girault   , known from the Nearctic region (Triapitsyn et al. 2010), but females of the latter two species have the antenna with F 1 deeply incised dorsoapically ( Huber 1988).

Hosts. Nephotettix cincticeps Uhler   (Cidadellidae) ( Sahad 1982 a [as G. sp. r], 1982 c [as G. miurai   ]; Sahad & Hirashima 1984 [as G. miurai   ]), as well as Nilaparvata lugens (Stål)   and Sogatella furcifera (Horváth)   ( Delphacidae   ) ( Zeya & Hayat 1995) [as G. tarae   ].
