RESUMO
In the framework of the taxonomic revision of South American Sericini (Coleoptera: Scarabaeidae: Melolonthinae), we examined the type specimens of the species described by Burmeister (1855) in the genus Astaena Erichson, 1847. A few taxa resulted to not belong to the South American Sericini fauna, either due to different geographical provenience or due to incorrect systematical placement within Sericini. Two new combinations and one new synonymy are proposed: Neoserica pubescens (Burmeister, 1855), new combination (= Neoserica subsetosa Ahrens Fabrizi, 2016: 121, new synonymy) and Manonychus robustus (Burmeister, 1855), new combination.

Phanaeini comprises about 160 species in 12 genera restricted to the Americas. Since the diversity of this tribe remains little known in several regions of Brazil, this study presents a guide to its 13 species with presence in the biologically rich and largely unexplored state of Roraima: Coprophanaeus (Coprophanaeus) abas (MacLeay, 1819), C. (C.) dardanus (MacLeay, 1819), C. (C.) gameziArnaud, 2002, C. (C.) jasius (Olivier, 1789), C. (Megaphanaeus) lancifer (Linnaeus, 1767), Oxysternon (Oxysternon) conspicillatum conspicillatum Werber, 1801, O. (O.) durantoniArnaud, 1984, O. (O.) ebeninum (Nevinson, 1890), O. (O.) festivum viridanum (Olsoufieff, 1924), O. (O.) silenus chicheryiArnaud, 2001, Phanaeus (Notiophanaeus) bispinusBates, 1868, P. (N.) bordoniArnaud, 1996 (first record from Brazil), and Sulcophanaeus faunus (Fabricius, 1775). The species of Dendropaemon were not considered herein because the genus is presently under taxonomic revision.
Phanaeini abrange cerca de 160 espécies pertencentes a 12 gêneros restritos ès Américas. Como a diversidade desta tribo permanece pouco conhecida em diversas regiões do Brasil, este estudo apresenta um guia de identificação das 13 espécies com registro de ocorrência no estado biologicamente rico e amplamente inexplorado de Roraima: Coprophanaeus (Coprophanaeus) abas (MacLeay, 1819), C. (C.) dardanus (MacLeay, 1819), C. (C.) gameziArnaud, 2002, C. (C.) jasius (Olivier, 1789), C. (Megaphanaeus) lancifer (Linnaeus, 1767), Oxysternon (Oxysternon) conspicillatum conspicillatum Werber, 1801, O. (O.) durantoniArnaud, 1984, O. (O.) ebeninum (Nevinson, 1890), O. (O.) festivum viridanum (Olsoufieff, 1924), O. (O.) silenus chicheryiArnaud, 2001, Phanaeus (Notiophanaeus) bispinusBates, 1868, P. (N.) bordoniArnaud, 1996 (que aqui é reportado pela primeira vez no Brasil), e Sulcophanaeus faunus (Fabricius, 1775). As espécies do gênero Dendropaemon não foram incluídas no trabalho por estarem em processo de revisão taxonômica.
