<p>In the Private Reserve, Refugio del Oso de Anteojos (El Calvario-Meta), the diversity of dung beetles was studied (Coleoptera: Scarabaeinae), grouped around different types of vegetation (Montane Rain Forest, Rainforest Premontane, Lower Montane Rain Forest), by using pitfall traps baited with human dung. During the samplings carried out in the rainy station on 2008, were captured a total of 177 individuals belonging to 9 species. The tribe Canthonini was the most representative with 87.5%, of the described species, followed by Aechini 10.8%, and Onthophagini 1.7%. The dominant species was Canthon lituratus in the three vegetation units: Lower montane rain forest was the richest (9 species) and abundance (86 individuals), compared with other environments sampled. By calculating the complementarity index, shows a similar species composition in the three habitats sampled, possibly, related to the floristic composition presented in each one of them.</p>
