Gonatocerus ( Cosmocomoidea ) triguttatus is a member of the ater subgroup of the ater species group. Its main distinguishing features are as follows: head and mesosoma of female generally yellow, gaster light yellow with brown bands on terga ( Fig. 474 ); mesonotum of male slightly darker, with light brown or brown areas; female antenna ( Fig. 472 ) with mps present on all funicle segments; propodeum ( Fig. 473 ) with submedian carinae thick, distinct, extending to its anterior margin; wings hyaline, forewing ( Figs 475 , 477 ) with cubital row of setae complete, extending to base of marginal vein. Also illustrated here are the male antenna ( Fig. 476 ) and genitalia ( Fig. 478 ). Gonatocerus triguttatus is closely related to G. ( Cosmocomoidea ) uat Triapitsyn and G. ( Cosmocomoidea ) ashmeadi Girault (see cladogram in Triapitsyn et al. 2006), both of which have a dark brown mesosoma in both sexes; it differs genetically from another closely related and morphologically very similar South American species G. ( Cosmocomoidea ) metanotalis (Ogloblin) (de León 2005; de León et al. 2006e), from which it can be separated by the presence of at least 1 (usually 2) mps on F1 of the female antenna (none in G. metanotalis ). FIGURES 476–478. Gonatocerus ( Cosmocomoidea ) triguttatus ♂ (from colony of Tamaulipas, Mexico, origin – California Department of Food and Agriculture Mt. Rubidoux Field Station, Riverside, California, USA): 476, antenna; 477, forewing; 478, genitalia. Distribution. NEOTROPICAL: Ecuador , Mexico , Nicaragua , Peru , and Trinidad and Tobago (Triapitsyn 2006a). NEARCTIC: Mexico , and USA ( California , Florida , Texas ) (Triapitsyn 2006a). Introduced into California against Homalodisca vitripennis (Germar) , initially from Tamaulipas , Mexico , and then from Texas and established there ( Morgan et al. 2000 ; Morgan et al. 2002; Triapitsyn, Bezark et al. 2002 ; Pilkington et al. 2005 ; Triapitsyn 2006a). Hosts. Homalodisca liturata Ball (under laboratory conditions and also likely in the field following introduction into southern California ), H. vitripennis (Germar) , Oncometopia clarior ( Walker ) , O. nigricans ( Walker ) , Oncometopia sp., and Pseudometopia amblardii (Signoret) or P. phalaesia (Distant) (Cicadellidae) (Triapitsyn 2006a).
