The specimens collected in the eastern Amazon Basin are smaller than the Brazilian populations (Fig. 10) (Feitosa and Brandão 2008). Distribution This is a Neotropical species reported from Brazil, Ecuador, Peru and Venezuela and is little known in Colombia with records from Amazonas, Meta and Nariño (Feitosa and Brandão 2008). It is reported here for the first time in the Department of Caquetá. Biology Species common in the leaf litter of humid forests, distributed from 200 to 1400 m elev.
