Flea beetles of the West Indies: the genus Hemilactica Blake, 1937 (Coleoptera, Chrysomelidae, Galerucinae, Alticini)

Abstract

The West Indian flea beetle genus Hemilactica Blake, 1937 is reviewed. Two new species, both from the Dominican Republic are described and illustrated: H. erwinisp. nov. and H. sierramatringarciasp. nov. In addition, images of the holotypes of H. portoricensis Blake, H. pulchella Blake, and H. rugosa Blake are provided. Lactica megaspila (Blake) is transferred to Hemilactica. A lectotype of H. quatuordecimpunctata (Suffrian, 1868) is designated and illustrated, and a key to the Hemilactica species and a key for identification of Hemilactica and related genera occurring in the Western Hemisphere are provided.
