Abstract

Colombia is one of the most biodiverse countries on the planet. However, economic and scientific investment in completing inventories of its biodiversity has been relatively poor in comparison with other Neotropical countries. Butterflies are the best studied group of invertebrates, with the highest proportion of known to expected species. More than 3,200 species of butterflies have been recorded in Colombia, although the study of the still many unexplored areas will presumably increase this number. This work provides a list of Ithomiini butterflies collected in the department of Antioquia and estimates the total number of species present, based on revision of entomological collections, records in the literature and field work performed between 2003 and 2011. The list includes 99 species and 32 genera, representing 27% of all Ithomiini species. We report 50 species of Ithomiini not formerly listed from Antioquia, and found the highest diversity of ithomiine species to be at middle elevations (900–1,800 m). The mean value of the Chao2 estimator for number of species in Antioquia is 115 species, which is close to a predicted total of 109 based on known distributions of other Ithomiini not yet recorded from the department. Nine species are potentially of particular conservation importance because of their restricted distributions, and we present range maps for each species. We also highlight areas in Antioquia with a lack of biodiversity knowledge to be targeted in future studies. This paper contributes to mapping the distribution of the Lepidoptera of Antioquia department in particular and of Colombia in general.
