Newly interpreted distributions for all three leopard frog species including "Rana kauffeldi". Symbols indicate known "R. kauffeldi" populations and purple shading depicts areas where our field work has confirmed the occurrence of "R. kauffeldi". Yellow shading indicates areas of less intensive examination and sampling; "R. kauffeldi" may occur in these areas based on habitat and proximity to known populations. Potential sympatry is also possible in the yellow shaded areas, with "R. sphenocephala" (from Long Island southward), or "R. pipiens" (north and west of Long Island). The type locality for "R. kauffeldi" is indicated by an arrow.
