Subgenus Anomoglossus Chaudoir, 1857

Anomoglossus Chaudoir, 1857: 4. Type species: Chlaenius emarginatus Say, 1823 designated by Bell (1960: 105). Etymology (original). From the Greek anomos (a bnormal) and glossa (tongue), alluding to the unusual shape of the ligula (" ligula omnino abnormis "), corresponding to the glossa and paraglossae or the glossal sclerite, of the adult [masculine].

Diversity.

Taxonomic Note.

The generic name Agreuter Lepeletier and Audinet-Serville (in Latreille et al. 1828: 633) was proposed for two species, Chlaenius chlorodius Dejean, 1826 and Chlaenius elegantulus Dejean, 1826 (= Chlaenius pusillus Say, 1823). Bousquet (2002b: 6) designated Chlaenius elegantulus as type species and so the name is listed as a synonym of Anomoglossus Chaudoir (e.g., Lorenz 2005: 333). However, Duponchel (1840a: 196) had selected Chlaenius chlorodius as the type species and so Agreuter is a senior synonym of Amblygenius LaFerté-Sénectère, 1851.
