Genus Erynephala Blake, 1936

Erynephala Blake, 1936: 425 (type species Galeruca maritima LeConte, 1865 , by original designation). Sarigueia Bechyné, 1956a: 302 (type species Galerucella subvittata Demay, 1838 , by original designation).

Remarks

This genus contains six described species, distributed from Canada to Argentina . The tarsal claws are bifid in males and simple in females. The elytra are covered with short setae, but these are sparse and inconspicuous in some species. Our key enables correct identification, even if the elytra are interpreted to be asetose. See Figs 34 and 151 for a habitus illustration and morphological details. See Groll et al. (2022) for a cladistic analysis and a key to the described species.
