Palaearctic species of the genus Scelolyperus Crotch, 1974 (Coleoptera: Chrysomelidae) are reviewed. Scelolyperus perreus sp. nov. from Turkey is described, illustrated and compared with Palaearctic species. Scelolyperus altaicus ssp. eous (Ogloblin, 1936) is elevated to species rank. Four taxa classified or associated with Scelolyperus are transferred elsewhere: Luperus pseudoaltaicus Medvedev, 1975 and Scelolyperus napolovi Medvedev, 2012 are transferred to Euluperus Weise, 1886; Adimonia glabra Fischer von Waldheim, 1842 is not conspecific with Scelolyperus sericeus (Jacobson, 1894) but belongs to the genus Agelastica Chevrolat, 1836 and A. alni orientalis Baly, 1878 is proposed as its new synonym; forgotten Eugalera seminigra Pic, 1903 is tentatively transferred to Luperus Geoffroy, 1762. The lectotypes are designated for Luperus altaicus ssp. eous and Adimonia glabra . Colour photo of habitus and both male and female genitalia are provided for all Palaearctic Scelolyperus species. Preliminary diagnostic table for Palaearctic “Luperus-like” genera is presented.
