Gonatocerus uat S. Triapitsyn in Triapitsyn et al. 2006: 58–62.

Type locality

Ciudad Valles, San Luis Potosí, Mexico.

Diagnosis

Gonatocerus uat is very similar to G. ashmeadi , from which it can be distinguished by F 1 of the female antenna usually having 2 (rarely 1) longitudinal sensilla ( Fig. 26) (always none in G. ashmeadi , Fig. 21) and also by the forewing blade being notably infuscated beyond venation, more conspicuously so behind the tip of the marginal vein ( Fig. 27) (at most with a faint, uniform brownish tinge in G. ashmeadi , Fig. 24). Triapitsyn et al. (2006) also provide molecular evidence of the clear separation between G. ashmeadi and G. u a t.

Distribution

Argentina, Mexico (Tamaulipas, San Luis Potosí), and Peru (Triapitsyn et al. 2006). In the Nearctic region, it is known only from Llera de Canales in Tamaulipas, Mexico, just north of the “border” between the Nearctic and Neotropical regions.
