Résumé des articles cités et commentaires :
A new genus of scarab beetle, Eideria Neita & Ocampo, and three new species, E. pentaphylla Neita & Ocampo, E. Glabripenis Neita & Ocampo, and E. pedroantonioi Neita & Ocampo, are described based on specimens collected in the drylands of Colombia and rainforests of Ecuador. Based on the evaluation of morphological characters and within the context of the current classification of the subfamily Melolonthinae, this genus is placed in the tribe Tanyproctini (formerly called Pachydemini). Diagnostic characters, illustrations, and an identification key are provided for the new species. The relationships of Eideria with other Neotropical Tanyproctini genera are discussed.
A. dentata and A. oblivia. Descriptions, diagnosis illustrations,
distribution maps and a key to all species of the genus are provided. The biogeography of the genus
and its systematic placement within Melolonthinae are here discussed.
The southern Neotropical genus Anahi Martínez is comprehensively revised and now includes three species: A. dentata Ocampo & Ruiz-Manzanos new species, A. guaraniticus Martínez, and A. oblivia Ocampo & Ruiz-Manzanos new species. The new species extend the distribution of the genus from Paraguay and Bolivia to Argentina. A. guaraniticus is redescribed and the characters that define the genus are extended to include A. dentata and A. oblivia. Descriptions, diagnosis illustrations, distribution maps and a key to all species of the genus are provided. The biogeography of the genus and its systematic placement within Melolonthinae are here discussed.
The Argentinean endemic genus Neogutierrezia Martínez, 1953 (Scarabaeidae : Rutelinae) is revised and seven new species are described: N. bicolor Ocampo & Ruiz-Manzanos, sp. nov., N. chelii Ocampo & Ruiz-Manzanos, sp. nov., N. galileoi Ocampo & Ruiz-Manzanos, sp. nov., N. lagosae Ocampo & Ruiz-Manzanos, sp. nov., N. payuniensis Ocampo & Ruiz-Manzanos, sp. nov., N. scutata Ocampo & Ruiz-Manzanos, sp. nov. and N. variabilis Ocampo & Ruiz-Manzanos, sp. nov. Species status is proposed for N. affinis Martínez stat. nov., which was formerly considered as subspecies of N. mirabilis Martínez. The genus Neogutierrezia now includes 10 species distributed in the Monte biogeographic province in Argentina. In order to clarify the systematic placement of the genus Neogutierrezia, a molecular phylogenetic analysis was performed using structurally aligned 28S rDNA sequences (expansion segments D2 and D3) from 23 taxa in Scarabaeoidea, including two representative species of Neogutierrezia. This is the first report of an annotated secondary structure alignment of the D2 and D3 segments of 28S rRNA that spans a wide sample of scarabaeoids, providing a useful homology template for further phylogenetic reconstruction in these and closely related beetles. Results of the molecular parsimony analysis strongly indicate that the genus is closely related to members of the Rutelinae (Scarabaeidae), and thus Neogutierrezia Martínez is transferred from Melolonthinae: Pachydemini to Rutelinae, new placement. A morphological cladistic analysis of the genus was also undertaken, including all the 10 known species in the genus plus two outgroup taxa in Rutelinae, and based on 53 adult characters. The most-parsimonious cladogram provides evidence for the monophyly of the genus, which shows three main clades, distributed in Central Monte and Southern Monte. The adult morphology of the 10 species is described and a key is provided, along with illustrations of the diagnostic characters. The biogeography of species in the genus is discussed.
The genus Pseudoliogenys Moser is reviewed and placed in the tribe Diplotaxini based on morphological characters. Liogenys bidentula Fairmaire is transferred to the genus Pseudoliogenys, with Pseudoliogenys flavida Moser as a junior synonym (new synonymy). Lectotypes are designated for both names. The gender of the genus Pseudoliogenys is clarified as feminine for the purposes of nomenclature.

The genus Ptyophis Redtenbacher, endemic to central Chile, is revised and now includes two species: P. paulseni (Philippi) and P. eiderae Mondaca and Ocampo, nov. sp. Redescription of the genus, diagnosis, key to species, illustrations and distribution map are provided. Based on morphological examination, we transfer Ptyophis from Tanyproctini to Macrodactylini, and hypothesized relationships with other Chilean macrodactylines. To preserve nomenclatural stability, a lectotype is designated for Ptyophis macrophylla Redtenbacher and a neotype is designated for Tetraphyllus paulseni Philippi. Observations on the habitat, natural history, and distribution of species are given.
