Gonatoceroides Girault, 1913 [155]: 255. Type species: Gonatocerus (Gonatoceroides) australicus Girault , by original designation. Synonymy by Girault (1915 [228]: 156).

Gastrogonatocerus Ogloblin, 1935: 65 . Type species: Gonatocerus membraciphagus Ogloblin by original designation. Subgenus of Gonatocerus .

Diagnosis. Gonatocerus belongs to the Gonatocerus group of genera. It is distinguished as follows: funicle 8- segmented ( Figs. 138 , 144 ); face with subantennal grooves; marginal vein with hypochaeta about midway between proximal and distal macrochaetae ( Fig. 135 ); pronotum longitudinally divided medially into two lobes. Fore, middle, and hind legs as in Figs. 140–142 . The two Australian species groups are distinguished as follows: Pronotal lobes abutting and dorsellum rhomboidal ( Fig. 145 ) (sulphuripes group); pronotal lobes clearly separated by a gap and dorsellum straplike ( Fig. 139 ) ( litoralis group). Male flagellum 11-segmented ( Figs. 136 , 146 ) and genitalia attached directly to apical sternite, not encapsulated in phallobase ( Fig. 137 ).

The only genera likely to be confused with Gonatocerus are Boudiennyia and Eustochomorpha , which also have an 8-segmented funicle in females. Eustochomorpha has a 2- or 3-segmented clava (entire in Gonatocerus ) and Boudiennyia has a long, slender petiole (similar to Polynema ) and a horizontal costula between the submedian carinae (petiole shorter and wider and propodeum without costula joining the submedian carinae in Gonatocerus ). Both these genera are extremely rare compared to Gonatocerus , whose species are abundant and often relatively large. Gonatocerus is perhaps the most frequently noticed mymarid genus in Australia because of the relatively large size of many of its species.

Body length. 666–1200 µm (sulphuripes group species); 663–2660 µm ( litoralis group species).

Distribution. Worldwide.

Hosts. Unknown for Australian species. Elsewhere reported from Cicadellidae and Membracidae .
