The authorship and type species of the genera Acentroptera and Metazycera are reviewed. The correct author of Acentroptera is Guérin-Méneville, 1844; Acentroptera dejeani Guérin-Méneville, 1844, is here designated as the type species. Metazycera is the correct spelling of the genus described by Chevrolat, 1837; the type species is Hispa trimaculata Olivier, 1808, by monotypy; Metaxycera Baly, 1864 is an unjustified emendation

A.http://www.centerforsystematicentomology.org/Insecta Mundi is a journal primarily devoted to insect systematics, but articles can be published onany non-marine arthropod taxon. Manuscripts considered for publication include, but are not limited to,systematic or taxonomic studies, revisions, nomenclatural changes, faunal studies, book reviews, phylo-genetic analyses, biological or behavioral studies, etc. Insecta Mundi is widely distributed, and refer-enced or abstracted by several sources including the Zoological Record, CAB Abstracts, etc.As of 2007, Insecta Mundi is published irregularly throughout the year, not as quarterly issues. Asmanuscripts are completed they are published and given an individual number. Manuscripts must bepeer reviewed prior to submission, after which they are again reviewed by the editorial board to insurequality. One author of each submitted manuscript must be a current member of the Center for System-atic Entomology.Managing editor: Paul E. Skelley, e-mail: insectamundi@gmail.comProduction editor: Michael C.

The authorship and type species of the genera Acentroptera and Metazycera are reviewed.  The correctauthor of Acentroptera is Guérin-Méneville, 1844; Acentroptera dejeani Guérin-Méneville, 1844, is here designatedas the type species.   Metazycera is the correct spelling of the genus described by Chevrolat, 1837; the type speciesis Hispa trimaculata Olivier, 1808, by monotypy; Metaxycera Baly, 1864 is an unjustified emendation.DiscussionThe name Acentroptera was first proposed by Chevrolat (1837) and included the species names A.lacordairei Dejean and A. regalis Chevrolat.  Neither species included a description, definition or indica-tion so they are nomina nuda (ICZN 1999, Article 12).  Guérin-Méneville (1844) validated the nameAcentroptera by describing the species A. dejeani from Brazil, A. norrisii from Cayenne, and A. cucullataand A. praeusta from Madagascar.  Thomson (1856) described the species A. basilica and A. alapista fromBrazil and unjustifiably emended the generic name to Acenthroptera.  Baly (1858) published the firstgeneric diagnosis, transferred Hispa pulchella Guérin-Méneville, 1830, to Acentroptera, described A.tessellata from Brazil, synonymized A. alapista Thomson with A. dejeani Guérin-Méneville, transferredA. cucullata Guérin-Méneville and A. praeusta Guérin-Méneville to Coelaenomenodera Blanchard, 1845,and designated A. pulchella as the type species of the genus.  Subsequent authors have incorrectly attrib-uted Acentroptera to Baly (1858) (Gemminger and Harold 1876; Weise 1911; Monrós and Viana 1947;Papp 1953; Uhmann 1957; Staines 2002), but the valid authorship belongs to Guérin-Méneville (1844).Baly’s type species designation is not valid since H. pulchella was not an originally included species(ICZN 1999, Article 69), but the designation has been followed by subsequent workers (Monrós and Viana1947; Uhmann 1957; Staines 2002).  In order to correct the existing error and to correctly establish thetype species of Acentroptera, I hereby designate A. dejeani Guérin-Méneville as the type species.The genus Metazycera was first proposed by Chevrolat (1837) who included the species M. aulicaDejean, M. purpurata Dejean, and M. trimaculata (Olivier).  Neither M. aulica nor M. purpurata in-cluded a description, definition or indication so they are nomina nuda (ICZN 1999, Article 12).   Chevrolatis the correct author of Metazycera because he transferred the species Hispa trimaculata Olivier, 1808, tothe new genus (ICZN 1999, Article 12.2.5).  Most authors have attributed this genus, spelled as Metaxycera,to Baly (1864) (Gemminger and Harold 1876; Weise 1911; Papp 1953; Uhmann 1957; Seeno and Wilcox1982; Staines 2002) who provided the first generic description, but the valid author is Chevrolat.Nomenclatural summary:Acentroptera Guérin-Méneville, 1844Acentroptera Chevrolat 1837: 388 Nomen Nudum.Acentroptera Guérin-Méneville, 1844: 271.
