Abstract

Eupontania Zinovjev, 1985, originally described as a subgenus of Pontania, is treated as a distinct genus of the subtribe Euurina Vikberg, which consists of the genera Euura Newman, Eupontania Zinovjev (stat. n.), Pontania A. Costa and Phyllocolpa Benson. Separate keys are given to distinguish these genera and the species-groups of Pontania and Phyllocolpa, and for 11 species of the Pontania crassispinu-group. A new species, Pontania rotundidentata sp. n. is described from eastern North America. The lectotypes are designated for P. crassispina (Thomson) and P. joergenseni Enslin. Pontania devincta MacGillivray (syn. n.) is treated as a synonym of P. populi Marlatt.
