"Dendrobates andinus, new species, is a small arboreal frog from wet montane forest (1700-2020 m elev.) on the Pacific versant of the Andes in extreme southwestern Colombia. Although its color pattern - yellowish dorsolateral stripes on a black or dark brown body - is reminiscent of two other Colombian species (D. truncatus and Phyllobates aurotaenia), D. andinus is not closely related to them. Dendrobates andinus is tentatively placed in the pictus species group, in which its closest relative seems to be D. erythromos Vigle and Miyata, from lowland rain forest on the Pacific side of Ecuador. The recently described 'Phyllobates' azureiventris Kneller and Henle, from Amazonian Peru, incidentally, is also transferred to the pictus group of Dendrobates. Natural history data for Dendrobates andinus include observations on courtship behavior and cephalic amplexus; individuals are most frequently associated with water-filled bromeliads, where clutches of three or four eggs are laid. Sound spectrograms and waveforms of the advertisement call of Dendrobates erythromos are provided for future comparison when recordings become available for D. andinus, whose call was perceived in the field as a series of well-spaced 'crreek' notes. The call of erythromos is termed a retarded chirp call and is briefly compared with the characteristic chirp call of the histronicus species of Dendrobates"--P. [1].
