Redescription. See Huber (1988).
Diagnosis. Gonatocerus (Cosmocomoidea) dolichocerus is a member of the bucculentus subgroup of the ater species group. Female antenna as in Fig. 294. Pronotum concolorous with remainder of mesosoma; propodeum (Fig. 295) with submedian carinae converging anterodorsally, not extending to anterior margin of propodeum; forewing (Fig. 296) usually with a complete cubital row of setae and without darker bands or spots. Superficially, it is easily confused with G. (Cosmocomoidea) ashmeadi Girault, but this latter species lacks an occipital sulcus from the back of the head so the gena, in lateral view, do not appear constricted next to the eye. In G. dolichocerus there is an occipital sulcus that is wider than long, flattened or indented above the foramen.
Distribution. NEOTROPICAL*: Mexico (Veracruz). NEARCTIC: Canada (Huber 1988), Mexico (Nuevo León), and USA. OCEANIA: French Polynesia (Society Islands, Tuamotu Archipelago: Tahiti Island (Grandgirard et al. 2007) and Moorea Island), and Hawaiian Islands (USA: Hawaii) (Huber & Beardsley 2000). Huber (1988) mentioned occurrence of this species in Mexico without providing further details on its distribution there.
Hosts. Gyponana sp. (Cicadellidae), as well as Stictocephala bisonia Kopp & Yonke [as Ceresa bisonia Kopp & Yonke] and Tortistilus pacificus (Van Duzee) [as Stictocephala pacifica Van Duzee] (Membracidae) (Huber 1988).
