Abstract

This paper presents a taxonomic revision of the genus Platycoelia Dejean (Coleoptera: Scarabaeidae: Rutelinae: Anoplognathini: Platycoeliina). Phylogenetic analyses of all species in the genus were conducted and the biogeography of the genus is discussed. The phylogenetic analysis supports the monophyly of Platycoelia and divides the genus into four major clades. Based on the cladistic analysis, the generic names Callichloris Burmeister, Leucopelaea Bates, and Epicallichloris Gutiérrez are considered synonyms of Platycoelia. Character states supporting monophyletic clades are discussed. Descriptions and keys to all taxa are included.

The genus Platycoelia was revised and now includes 62 species, 19 of which are described as new. The new species are: P. aenigma, P. altiplana, P. butleri, P. convexa, P. flavohumeralis, P. furva, P. galerana, P. grandicula, P. hiporum, P. ignota, P. inca, P. insolita, P. interstincta, P. meridensis, P. paucarae, P. peruviana, P. pusilla, P. sandia, P. traceyae. The following species group names are placed in synonymy: P. boliviensis Blanchard (= P. pomacea Erichson), P. brasiliensis Ohaus (= P. pomacea Erichson), P. limbata Ohaus (= P. prasina Erichson), P. nigricauda Bates (= P. parva Kirsch), P. proseni Martinez (= P. burmeisteri Arrow), P. pulchrior Ohaus (= P. chrysotina Ohaus), P. tucumana Ohaus (= P. inflata Ohaus). Lectotypes were selected for the following names: Callichloris baessleri Ohaus, C. bocki Ohaus, C. helleri Ohaus, C. signaticollis Burmeister, Leucopelaea baron is Ohaus, Melolontha flavostriata Latreille, P. abdominalis Ohaus, P. alternans Erichson, P. boliviensis Blanchard, P. burmeisteri Arrow, P. burmeisteri Ohaus, P. chrysotina Ohaus, P. confluens Ohaus, P. flavoscutellata Ohaus, P. forcipalis Ohaus, P. gaujoni Ohaus, P. hirta Ohaus, P. humeralis Bates, P. inflata Ohaus, P. inflata tucumana Ohaus, P. intermedia Ohaus, P. laevis Burmeister, P. limbata Ohaus, P. lutescens Blanchard, P. marginata Burmeister, P. mesosternalis Ohaus, P. nervosa Kirsch, P. nigrocauda Bates, P. nigrosternalis Ohaus, P. occidentalis Ohaus, P. olivacea Blanchard, P. parva Kirsch, P. pomacea Erichson, P. pomacea brasiliensis Ohaus, P. prasina Erichson, P. pulchrior Ohaus, P. puncticollis Ohaus, P. quadrilineata Burmeister, P. rufosignata Ohaus, P. scutellata Guerin-Meneville, P. simplicior Ohaus, P. steinheili Ohaus, P. tschudii Ohaus, P. unguicularis Ohaus, P. valida Burmeister, P. variolosa Ohaus, P. wallisi Ohaus. Neotypes were designated for Callichloris alticola Gutiérrez and Callichloris laelaps Gutiérrez.

Resumen. Este trabajo presenta una revision taxonomica del genero Platycoelia Dejean (Coleoptera: Scarabaeidae: Rutelinae: Anoplognathini: Platycoeliina). Se realizaron analisis filogeneticos de todas las especies y la biogeografia del genero es discutida. El amilisis filogenetico soporta la monofilia de Platycoelia y divide el genero en dos clados. Basado en el amilisis cladistico, los nombres genericos Callichloris Burmeister, Leucopelaea Bates, y Epicallichloris Gutiérrez son considerados sinonimos de Platycoelia. Los carecteres que dan soporte a los clados son discutidos. Descripciones y claves para los taxa son incluidas.
