Anomonyx Saylor, 1940

Anomalonyx Moser, 1921: 156 (non Weise, 1903).

Anomonyx Saylor, 1940: 46 (replacement name for Anomalonyx).

Type species

Anomalonyx uruguayensis Moser, 1921 (designation: monotypy).

Diagnosis

Clypeal ventral area large and vertically deflected; labrum slightly emarginate; pronotal anterior and posterior margins not beaded; prosternum with an anterior longitudinal carina; elytral striae indistinct, posterior margin not beaded and posterointernal margin beaded; metatarsomere I as long as II+III (Fig. 4 B); metatarsomere V with internoproximal spine-like setae (Fig. 4 B).

Remarks

The genera Anomonyx, Oedichira Burmeister, 1855 and Plectris LePeletier de Saint-Fargeau & Audinet-Serville, 1828 are similar to each other. Anomonyx is distinguished as follows (opposition to 1, Oedichira; 2, Plectris): clypeal ventral area vertically deflected (1, as Anomonyx; 2, vertically deflected or not); metatarsomere I as long as II+III (1, 2, as long as II–IV); metatarsomere II at least twice as long as wide (1, wider than long; 2, as Anomonyx). Future cladistic analyses and a taxonomic review of Plectris including Anomonyx and Oedichira are needed to determine the possible synonymy between these genera.
