A new species, Podontia rustiai Calcetas and Staines (Coleoptera: Chrysomelidae: Galerucinae: Alticini) in the Philippines, is described. The species Podontia flava Baly, 1865 is very similar and known from Borneo (Sarawak, Sabah) and Brunei is redescribed, and the introduced Podontia quatuordecimpunctata (L., 1767) is contrasted and compared. However, the endophallic median sclerite of the paramere of the male genitalia in P. flava is whip-like and apically tapered, whereas it is shield-like and apically rounded in P. rustiai new species. A key to the genus Podontia in the Philippines and Sarawak is provided.
