039A7C4D677F1E2377D7FF67FC4E261F.taxon	description	Acentroptera belongs to the tribe Sceloenoplini, which contains five genera (Staines 2002 a). Acentroptera can be distinguished from all other Sceloenoplini by the following combination of characters: body moderately convex; anterior pair of legs as long as other pairs; elytra with exterior apical angle not expanded laterally; and elytra is curved after interspace 6.	en	Staines, C.

039A7C4D67781E2577D7F9C7FB12263F.taxon	discussion	Discussion. Baly (1858) thought A. basilica may be a synonym of A. pulchella, but he had not seen any specimens of the later species. However, Thomson’s (1856) description is very detailed and is definitely refers to a separate species. Monrós and Viana (1947) obtained specimens from Argentina and Paraguay that agree with the original description, which have been examined. Requests from major museums in Europe (BMNH, DEI, MNHN, and ZMHB) failed to locate additional specimens. While a case could be made for the designation of a neotype, the nomenclatural status of the species is firmly established in the literature and therefore does not meet the requirements of Article 75 (ICZN 1999).	en	Staines, C.

039A7C4D677A1E2777D7FCA7FE54237F.taxon	discussion	Discussion. Baly (1858) merely repeated Guérin-Méneville’s (1844) original description, which is detailed enough to confidently assign specimens to the species name. Since the original description was based on specimens from the Chevrolat and Dejean collections, which were widely dispersed, the type specimen may exist in a smaller museum in Europe. Therefore a neotype designation is not justified at this time.	en	Staines, C. L. (2014): A revision of the genus Acentroptera Guérin-Méneville, 1844 (Coleoptera: Chrysomelidae: Cassidinae).

Adults feed on the distal parts of leaves, scraping the epidermis in long narrow strips (2 - 5 mm wide and up to 100 mm long). Wounded tissue dried and became cork-like in appearance and red in color. Adult beetles were more active at lower temperature and on cloudy days, they were seldom observed in the warmest part of sunny days. Specimens examined: Brazil: no further data (BMNH).

039A7C4D67721E2E77D7FF67FE52247F.taxon	discussion	Discussion. This species was described from a single specimen from Brazil in the Parry collection and deposited in the BMNH. A detailed examination of the BMNH collection by the author and S. L. Shute (BMNH) failed to locate the holotype. Specimens identified as A. tessellata were not found in the DEI, MNHN, NRM, and ZMHB collections. I therefore concluded that the holotype has been lost or destroyed. Baly’s (1858) description is detailed enough to determine specimens from the BMNH and USNM collections as A. tessellata. Since the name had only been mentioned in catalogs and a more detailed description had not been published, a neotype is hereby designated to clarify the nomenclatural status of this species name (ICZN 1999, Art. 75).	en	Staines, C.
