Redescription and identity of Taphinella bengalensis Jacoby, 1900(Coleoptera: Chrysomelidae: Galerucinae)

The primary type specimens of Taphinella bengalensis Jacoby, 1900 (type species of Taphinellina Maulik, 1936) were examined. The genus Taphinellina is excluded from synonymy with Charaea Baly, 1878 and newly synonymized with Cassena Weise, 1892. Taphinella bengalensis is transferred to Cassena and redescribed, and its lectotype is designated. Color photos of its habitus and drawings of both male and female genitalia are presented.
