Gonatocerus Nees View in CoL ( litoralis View in CoL species group): Matthews 1986: 216 (key), 222–223; Huber 1988: 30 –32; Yoshimoto 1990: 37 –38; Zeya & Hayat 1995: 91 –94.

Gonatocerus Nees View in CoL ( straeleni species group, without a formal synonymy of Decarthrius [then a synonym of Gahanopsis Ogloblin View in CoL ] under Gonatocerus View in CoL ): Huber 1988: 24; Yoshimoto 1990: 37.

Diagnosis. Face with subantennal sulci widely separated from each other at junction with clypeus; back of head without sutures; pronotum divided into 2 lobes widely separated by lightly sclerotized median area, except narrowly separated in a few Afrotropical species and median area sometimes strongly sclerotized in some Australasian species; female funicle usually 8-segmented, rarely 7-segmented (mostly in some Afrotropical species); dorsellum strap-like, with posterior margin straight and parallel with anterior margin; propodeum with submedian lines instead of a median carina or submedian carinae (except in some Afrotropical species) and the area between them flat and often bearing minute spicules; forewing with cubital row (at least) of setae extending to base of marginal vein (except in some Afrotropical and Australasian species).

Distribution. Cosmopolitan.

Hosts. In the New World the known, reliable host records of G. ( Lymaenon ) are from eggs of Cicadellidae .

Comments. Gonatocerus (Lymaenon) straeleni (Debauche) , comb. n. from Gahanopsis Ogloblin , clearly belongs to G. ( Lymaenon ), hence the proposed synonymy of Decarthrius Debauche. The female antenna of this species has 7 funicle segments (apparently due to fusion of F1 and F2), all of which are much longer than wide. All other structural features match those of G. ( Lymaenon ). Males of G. straeleni were previously unknown, the antennae of males from Kenya * [UCRC] have a long, 11-segmented flagellum.

Gonatocerus (Lymaenon) anthonomi Girault View in CoL was mentioned by De Santis (1979) from Mexico but without indicating any locality; it is not considered in this review because we have not seen any determined specimens from the Neotropical part of Mexico. The senior author found in USNM a slide-mounted female specimen labeled: “ Gonatocerus View in CoL anthonomi Gir. Gahan. On View in CoL redishes from Juarez, Mex. Oct. 13:42. R.O. Collier. El Paso 35902”. According to the label, it was intercepted at the USA-Mexico border in El Paso, Texas, USA; the origin was Ciudad Juárez, Chihuahua, which is in the Nearctic part of Mexico. This specimen, which belongs to G. (Lymaenon) litoralis (Haliday) View in CoL , was the likely reason for the above-mentioned record by De Santis (1979).
