Ten new species in the Phyllophaga Harris subgenus Cnemarachis Saylor (Coleoptera: Scarabaeidae: Melolonthinae: Melolonthini) were discovered during a May 2013 field expedition in Cuba. These new species are Phyllophaga (Cnemarachis) andersoni Smith and Paulsen, Phyllophaga (Cnemarachis) bretti Smith and Paulsen, Phyllophaga (Cnemarachis) calai Smith and Paulsen, Phyllophaga (Cnemarachis) deleri Smith and Paulsen, Phyllophaga (Cnemarachis) falcata Smith and Paulsen, Phyllophaga (Cnemarachis) holguinensis Smith and Paulsen, Phyllophaga (Cnemarachis) manibota Smith and Paulsen, Phyllophaga (Cnemarachis) perfidia Smith and Paulsen, Phyllophaga (Cnemarachis) sarlacca Smith and Paulsen, and Phyllophaga (Cnemarachis) secessicola Smith and Paulsen. Each species is described, illustrated, and diagnosed. A checklist of the species of Phyllophaga in Cuba by province is given.

While reviewing the literature, we discovered problems and confusion with three species of North American Lucanidae that require clarification and correction. The name Platycerus quercus (Weber, 1801) (Lucaninae: Platycerini) (formerly Platycerus virescens (Fabricius, 1775)) is revalidated since the Fabricius name is correctly classified as Temnochila virescens (Fabricius, 1775) (Coleoptera: Trogossitidae). Since there was much confusion over the classification of the name Temnochila virescens (Fabricius, 1775), a neotype is designated for this species. We use a reversal of precedence under Article 23.9.2 of the International Code of Zoological Nomenclature to give Lucanus piceusWeber, 1801 nomen protectum (now Ceruchus piceus (Weber, 1801), Syndesinae) precedence over the primary homonym Lucanus piceusBonsdorff, 1785nomen oblitum (now a junior synonym of Ceruchus chrysomelinus (Hochenwarth, 1785)). To clarify the author and date of Lucanus capreolus (Linnaeus, 1763) (Lucaninae: Lucanini), we detail the origin of the name. An updated checklist of the Lucanidae of North America north of Mexico is provided.

Podolasia diabla Smith and Paulsen, new species and Podolasia parapilosa Smith and Paulsen, new species (Coleoptera: Scarabaeidae: Melolonthinae: Podolasiini) are described from dune habitats in Coahuila, Mexico. The new species are illustrated, and diagnostic characters are discussed to separate them from previously described species. Podolasia diabla is notable as the first species known from this tribe with head horns.

Replacement Names for the Genera Batesiana Erwin (Coleoptera: Carabidae) andMetabolus Fairmaire (Coleoptera: Scarabaeidae: Melolonthinae)While curating scarab beetles in the University of Nebraska State Museum collection, wediscovered two generic names that are homonyms. As this renders these names invalid, we hereinpropose replacement names for the junior homonyms as follows.Erwiniana Paulsen and Smith new genus¼Batesiana Erwin, 1994:581.Batesiana Erwin, 1994 (Coleoptera: Carabidae: Bembidiini) is a junior homonym of BatesianaChalumeau, 1983 (Coleoptera: Scarabaeidae: Aphodiinae). We propose Erwiniana new genus asa replacement name and an objective synonym of Batesiana Erwin as delineated in Articles 60.3and 72.7 of the International Code of Zoological Nomenclature (1999). The name Erwiniana(gender feminine) honors Terry L. Erwin (Smithsonian Institution, Washington, D.C. U.S.A.) whodescribed many of the 57 currently recognized species in the genus. The type species of Batesiana(Xystostomus gruti Bates by original designation) automatically becomes the type species ofErwiniana. The species of Batesiana listed in Erwin (1994) are thus placed in a new combinationwith the valid name Erwiniana.Ablotemus Paulsen and Smith new genus¼Metabolus Fairmaire, 1887:107.Metabolus Fairmaire, 1887 (Coleoptera: Scarabaeidae: Melolonthinae) is a junior homonymof Metabolus Bonaparte, 1854 (Aves: Passeriformes: Monarchidae). We propose the nameAblotemus new genus as a replacement name and an objective synonym of Metabolus Fairmaire.The etymology of the name Metabolus (gender masculine) remains unclear, thus we have chosenthe replacement name Ablotemus (gender masculine), an anagram of the original generic name.The type species of Metabolus (M. tumidifrons Fairmaire bymonotypy) automatically becomes thetype species of Ablotemus. The species currently considered to be in the genus Metabolus arehereby transferred to the genus Ablotemus.This publication was supported by NSF/PEET grants DEB-9712447 to B. C.
