A taxonomic review of the neotropical genus Coprophanaeus Olsoufieff, 1924 (Coleoptera: Scarabaeidae, Scarabaeinae

The Neotropical genus Coprophanaeus Olsoufieff (1924), as classified here, comprises 38 species distributed among three subgenera (Megaphanaeus Olsoufieff, Metallophanaeus Olsoufieff, and Coprophanaeus s. str. ) and eight species groups. Keys presented help to identify supraspecific and species taxa, all of which are illustrated and diagnosed. Lectotypes are designated for Phanaeus ignecinctus Felsche and Phanaeus ohausi Felsche. Coprophanaeus corythus (Harold), formerly regarded as a subspecies of C. telamon (Erichson), assumes species status. Coprophanaeus magnoi Arnaud, described as a subspecies of C. milon (Blanchard), is raised to species status. New taxonomic interpretations result in 10 new subjective synonymies (junior synonym listed first): Phanaeus machadoi Pereira and d’Andretta = Coprophanaeus saphirinus (Perty); Phanaeus costatus Olsoufieff = Coprophanaeus cyanescens (Olsoufieff); Phanaeus worontzowi Pessôa and Lane = Coprophanaeus cyanescens (Olsoufieff); Coprophanaeus kohlmanni Arnaud = Coprophanaeus morenoi Arnaud; Coprophanaeus pluto nogueirai Arnaud = Coprophanaeus pluto (Harold); Coprophanaeus edmondsi Arnaud = Coprophanaeus conocephalus (Olsoufieff); Coprophanaeus uhleri Malý and Pokorný = Coprophanaeus chiriquensis (Olsoufieff); Coprophanaeus henryi Malý and Pokorný = Coprophanaeus gilli Arnaud; Phanaeus perseus Harold = Coprophanaeus corythus (Harold); Coprophanaeus telamon nevinsoni Arnaud and Gámez = Coprophanaeus corythus; and Coprophanaeus florenti Arnaud = Coprophanaeus ohausi (Felsche). The status of the following names remains unresolved: Phanaeus strandi Balthasar; Coprophanaeus rigoutorum Arnaud; C. terrali Arnaud; C. lichyi Arnaud; C. lecromi Arnaud; C. larseni Arnaud; and C. vazdemeloi Arnaud.

CLARIFICATION ON THE NOMENCLATURAL STATUS OF SIX GENUS-GROUP NAMES IN THE TRIBE TRICHIINI (COLEOPTERA: SCARABAEIDAE: CETONIINAE)

Six genus-group names in the tribe Trichiini (Coleoptera: Scarabaeidae: Cetoniinae) are discussed with regards to their availability and validity under the International Code of Zoological Nomenclature. Aleurostictus Kirby, Archimedius Kirby, Euclidius Kirby, Gymnodus Kirby, Tetrophthalmus Kirby, and Trichinus Kirby all have priority over most other generic names in the tribe but none of the names are in prevailing usage. Clarifications are needed due to the reemergence of Aleurostictus Kirby in current literature and confusion over the nomenclatural status of the other names. Type species are designated for Aleurostictus Kirby, Tetrophthalmus Kirby, and Stegopterus Burmeister and Schaum. The gender of the genera Trigonopeltastes Burmeister and Schaum and Apeltastes Howden is also discussed.

Revision of the genus Holocephalus (Coleoptera: Scarabaeidae: Scarabaeinae: Coprini)

The genus Holocephalus Hope is revised and now contains five species: H. cristatus (Gillet), H. eridanus (Olivier), H. julieni sp.nov. H. sculptus (Gillet), and H. simoni sp.nov. All taxa are described and illustrated. A key to speies of Holocephalus is included. Lectotypes are designated for H. eridanus and H. sculptus. Scarabaeus eridanus Olivier is designated as the type species for the generic name Atrichius Gillet (a junior synonym of Holocephalus). On révise le genre Holocephalus Hope qui regroupe maintenant cinq es-pèces, soit H. cristatus (Gillet), H. eridanus (Olivier), H. julieni sp.nov., H. sculptus (Gillet) et H. simoni sp.nov. Outre les descriptions et illustrations pour chaque espèces on propose un tableau de détermination pour les espèces maintenant comprises dans le genre Holocephalus. On désigne des lectypes pour H. eridanus et H. sculptus. Enfin, on désigne l’espèce Scarabaeus eridanus Olivier comme type du genre Atrichius Gillet (considéré comme synonymec junior du genre Holocephalus).

EREMOPHYGUS BICOLOR (GUTIÉRREZ) (COLEOPTERA: SCARABAEIDAE: RUTELINAE: RUTELINI): A NEW TRIBAL AND GENERIC PLACEMENT FOR THE BOLIVIAN SCARAB PLATYCOELIA BICOLOR (GUTIÉRREZ) (ANOPLOGNATHINI)

Platycoelia bicolor (Gutiérrez) (Scarabaeidae: Rutelinae) is transferred from the tribe Anoplognathini, subtribe Platycoeliina, to the tribe Rutelini. Platycoelia bicolor is placed in the genus Eremophygus Ohaus and the taxonomic history of the species is discussed. The transfer creates a new combination, Eremophygus bicolor (Gutiérrez) and places the generic name Heterocallichloris Gutiérrez as a junior synonym of Eremophygus (new synonymy). Morphological characters that warrant the transfer are discussed. Se transfiere Platycoelia bicolor (Gutiérrez) (Scarabaeidae: Rutelinae) de la tribu Anoplognathini, subtribe Platycoeliina, a la tribu Rutelini. Se transfiere Platycoelia bicolor al género Eremophygus Ohaus y se discute su historia taxonómica. La transferencia crea una nueva combinación, Eremophygus bicolor (Gutiérrez) y ubica al nombre genérico Heterocallichloris Gutiérrez como un sinónimo junior de Eremophygus. Se discuten los caracteres morfológicos que justifican la transferencia.
