Diagnosis. Gonatocerus (Cosmocomoidea) walkerjonesi is a member of the morrilli subgroup of the ater species group. It is very similar to G. (Cosmocomoidea) morrilli (Howard), from which it differs by the propodeum (Fig. 500) having the submedian carinae curved and more apart from each other. Male genitalia of these two species are also different. In G. walkerjonesi the apodeme of the genital sternite is notably longer than the aedeagal apodemes (Fig. 504). Gonatocerus walkerjonesi is even more similar morphologically, especially the propodeal submedian carinae, and apparently more closely related genetically to the South American species G. (Cosmocomoidea) annulicornis (Ogloblin) (de León et al. 2005). This latter species lacks the dark cloud on the forewing in both sexes (Figs 185, 191, 194) and males have a relatively shorter antenna (Fig. 192) and are generally lighter colored (particularly the mesosomal dorsum) than males of G. walkerjonesi. Also illustrated here are the antenna (Fig. 499) and forewing (Fig. 501) of the female, as well as the antenna (Fig. 502) and the forewing (Fig. 503) of the male.
Distribution. NEOTROPICAL: Nicaragua (Triapitsyn 2006a). NEARCTIC: USA (California) (Triapitsyn 2006a).
Hosts. Homalodisca liturata Ball and H. vitripennis (Germar) (Cicadellidae) (Triapitsyn 2006a).
