The traditional division of hispines and cassidines is rejected as inadequate. The name of the subfamily is Cassidinae. The tribe hnatidiini Hincks 1952 is synonymized with Cephaloleiini Chapuis 1875 (new synonym). Oediopalpini Monros 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. Ocuosispa Weise 1910 and Pseiidispci 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. Key Words: Cassidinae, hispines, genera Hispines (Coleoptera: Chrysomelidae: Cassidinae) are a group of approximately 3,000 species worldwide (Uhmann 1957b, 1958, 1964; Seeno and Wilcox 1982). Cur-rently they are placed in 170 genera and 24 tribes (Seeno and Wilcox 1982). According to the present classification, there are no tribes or genera indigenous in both the Old and New Worlds. Weise (1911) published the most recent key to the New World genera, covering the 49 genera described by that date. He (Weise 1910, 1911) also proposed the tribal clas-sification that is still in use. There has been little change in the higher classification since then. In proposing his tribal classifi-cation Weise latinized the names proposed by Chapuis (1875) but did not attribute the names to Chapuis. Subsequent authors have attributed the tribal names to Weise (1910, 191 1) but the author is Chapuis [ICZN Ar-ticle 11(f) (1999)]. Uhmann (1957b, 1964) compiled the most recent catalog, contain-ing 82 genera and 1,391 species. Seeno and Wilcox ( 1982) recorded 83 genera from the New World. There have been several regional revi-sions of New World hispines. The most comprehensive of these are Monros and Vi-ana (1947) for Argentina and Staines (1996b) for Nicaragua. Other works are Blaisdell (1939), Butte (1968a, b, c, 1969). Clark (1983) and Riley (1985) on certain genera in America north of Mexico; San-derson (1967) on the West Indies hispines; Uhmann (1930a, b, 1934, 1935c. 1937c) on Costa Rican species; Ramos (1998) on Bra-zilian Oxychalepus, and Staines ( 1996a) the Central American and West Indian Cephal-oleia. Fourteen genera have been treated for the entire New World: Fischer (1935) re-vised Coraliomela, Mecistomela, Ahirnus, and Pseiidocalaspidea; Spaeth (1938) re-vised Imatidiuin (now divided into Aslam-
