The new world tribes and genera of Hispines (Coleoptera, Chrysomelidae: Cassidinae)

The tribes and genera of New World hispines are revised and a key to the 98 genera is presented. The traditional division of hispines and cassidines is rejected as inadequate. The name of the subfamily is Cassidinae. The tribe Imatidiini Hincks 1952 is synonymized with Cephaloleiini Chapuis 1875 (new synonym). Oediopalpini Monrós and Viana 1947 is synonymized with Spilophorini Chapuis 1875 (new synonym). The tribes Delocrariini Hincks 1952 and Hemisphaerotini Hincks 1952 are treated since they are often confused with hispines. Ocnosispa Weise 1910 and Pseudispa Chapuis 1875 are elevated to full generic status. Plicatopalpa Pic is synonymized with Uroplata Chevrolat (new synonym). Serratispa quadricosta, n. gen., n. sp. from Brazil is described and placed in the tribe Sceloenoplini.
