FIGURE 2. Interpopulation variation in Ameerega altamazonica. Individuals in the top row are from near Tarapoto (holotype), Chazuta, and Saposoa (left to right); individuals in the middle row are from Río Abiseo, Campanilla, and Tocache (left to right). In the Huallaga valley there is a cline from a black dorsum with well-defined dorsolateral stripes in the northern populations (e.g. Tarapoto) to a brown dorsum with dorsolateral stripes faint or absent in southern populations (e.g. Tocache). Bottom row showing ventral pattern in adults from Tarapoto, Río Abiseo, and Tocache (left to right).
