Fig. 1. Distribution map of known localities for Nymphargus balionotus. Information tags to the left summarize data reported for each locality, including (in order): name of collection site, department/province, number of specimens reported, elevation, and year specimens were collected or observed. Blue circle represents the Río Manduriacu Reserve; red circle marks the type locality; yellow and gray circles represent remaining localities reported in the literature, with the gray (Campamento Chancos) population believed to be a distinct lineage by Cisneros-Heredia and McDiarmid (2006). Note: the "El Tambo" locality in the department of Cauca, Colombia, has been placed as accurately as possible based on available information (see Discussion).
