Clave ilustrada para la identificación de géneros de escarabajos coprófagos (coleoptera: scarabaeinae) de Colombia

En Colombia los escarabajos coprófagos de la subfamilia Scarabaeinae están representados por aproximadamente 34 géneros y 380 especies. A pesar de que este grupo de insectos está siendo objeto de múltiples estudios ecológicos en el país, no se cuenta con literatura apropiada para la identificación de los taxones incluidos. Este trabajo presenta una clave ilustrada para la identificación de los géneros de escarabajos coprófagos presentes en Colombia.In Colombia the dung beetles of the subfamily Scarabaeinae are represented by approximately 34 genera and 380 species.

Escarabajos coprófagos (Coleoptera: Scarabaeidae: Scarabaeinae) de los páramos del departamento de Nariño, Colombia

We report the presence of several dung beetle species (Coleoptera: Scarabaeidae: Scarabaeinae) in the Paramos located in Nariño, Colombia, based on the revision of museums specimens, field work and available literature. 210 specimens from three national museums and 362 individuals from collecting trips done by the Nariño University, GAICA Association and the authors were studied. A total of eight species from seven genera and 21 localities were listed. Uroxys elongatus Harold, 1868 is the species with most individuals collected or found in collections. Only one individual of Ontherus brevicollis Kirsch, 1871 and Oruscatus opalescens Bates, 1870 was found. The altitudinal range under study goes from 2800 to 3700 meters, corresponding to the highest altitude reported for U. elongatus, additionally we report the localities for two species, O. opalescens and Dichotomius monstrosus (Harold, 1875), with few or no confirmed data, increasing the knowledge for these species for Colombia.Se presenta información sobre las especies de escarabajos coprófagos (Coleoptera: Scarabaeidae: Scarabaeinae) que habitan los páramos del departamento de Nariño, Colombia, basados en revisión de colecciones, recopilación de trabajos de campo y literatura disponible para el área de estudio. Se revisaron 210 ejemplares depositados en tres colecciones entomológicas nacionales y se reportaron en total 362 individuos colectados en caracterizaciones biológicas realizadas por la Universidad de Nariño, la Asociación GAICA y muestreos particulares de los autores, registrándose un total de ocho especies y siete géneros de escarabajos coprófagos en 21 localidades del departamento. Uroxys elongatus Harold, 1868 es la especie con mayor número de individuos colectados y ejemplares en colecciones, mientras que Ontherus brevicollis Kirsch, 1871 y Oruscatus opalescens Bates, 1870 estuvieron representados por un solo ejemplar. El listado incluye localidades desde los 2800 hasta los 3700 m s.n.m. correspondiente a los registros con mayor altura para U. elongatus, además se presentan las localidades para dos especies con registros escasos o inespecíficos en Colombia, O. opalescens y Dichotomius monstrosus (Harold, 1875), actualizando la información de estas especies para Colombia

Escarabajos coprófagos (Coleoptera: Scarabaeidae: Scarabaeinae) de Colombia

Los escarabajos coprófagos son un gremio bien definido de la familia Scarabaeidae, subfamilia Scarabaeinae, que comparten características morfológicas, ecológicas y de comportamiento particulares (Halffter 1991). Sus principales distintivos biológicos son la asociación con el excremento y/o carroña de mamíferos y otros vertebrados, su especial modo de reproducción, así como las múltiples estrategias de aprovechamiento del excremento para su alimentación y reproducción (Halffter & Matthews 1966; Halffter & Edmonds 1982

Taxonomic reassessment of the genus Dichotomius (Coleoptera: Scarabaeinae) through integrative taxonomy

Dung beetles of the subfamily Scarabaeinae are widely recognised as important providers of multiple ecosystem services and are currently experiencing revisions that have improved our understanding of higher-level relationships in the subfamily. However, the study of phylogenetic relationships at the level of genus or species is still lagging behind. In this study we investigated the New World beetle genus Dichotomius, one of the richest within the New World Scarabaeinae, using the most comprehensive molecular and morphological dataset for the genus to date (in terms of number of species and individuals). Besides evaluating phylogenetic relationships, we also assessed species delimitation through a novel Bayesian approach (iBPP) that enables morphological and molecular data to be combined. Our findings support the monophyly of the genus Dichotomius but not that of the subgenera Selenocopris and Dichotomius sensu stricto (s.s). Also, our results do not support the recent synonymy of Selenocopris with Luederwaldtinia. Some species-groups within the genus were recovered, and seem associated with elevational distribution. Our species delimitation analyses were largely congruent irrespective of the set of parameters applied, but the most robust results were obtained when molecular and morphological data were combined. Although our current sampling and analyses were not powerful enough to make definite interpretations on the validity of all species evaluated, we can confidently recognise D. nisus, D. belus and D. mamillatus as valid and well differentiated species. Overall, our study provides new insights into the phylogenetic relationships and classification of dung beetles and has broad implications for their systematics and evolutionary analyses.

Here we present the first distribution record for Eurysternus foedus in the Macizo de la Sierra Nevada de Santa Marta province (Magdalena, Colombia) as the result of species inventory in the RNN El Congo, Municipio of Cienaga. Even though this specie is widely distributed it had not been previously collected in any of the recent studies developed in the region. This adds to the species richness of theSierra and highlights the overall lack of information on this provincebiodiversity
