Abstract

The phytophagous scarab genus Macraspis MacLeay (Scarabaeidae, Rutelinae, Rutelini) is reviewed from the Brazilian Amazon region. Three new species are described and illustrated from the states of Amazonas, Pará, and Rondônia: M. buehrnheimisp. nov., M. opalasp. nov., and M. phallocardiasp. nov. Two species, Macraspis fernandezi Neita-Moreno and M. oblonga Burmeister, are recorded for the first time in Brazil (new country records). Macraspis maculata crosarai Soula is a new synonym of Macraspis maculata Burmeister; hence this species no longer includes subspecies. Furthermore, Macraspis cincta parensis Soula, 2005 is deemed unavailable under the provisions of ICZN Articles 16.4.1 and 16.4.2. An illustrated key to 15 species and subspecies of Macraspis from the Brazilian Amazon enables identification of this speciose leaf chafer genus.
