Abstract
A probable instance of convergent evolution, involving the monotypic genus Anotheca, was detected by comparative studies of serum albumin. Anotheca albumin was as similar to the albumins of several North American Hyla as the albumins of the North American Hyla are to one another. Anotheca albumin was very different from the albumins of the marsupial tree frogs, as different as are those of Hyla. Phylogenetic analysis of the albumin data indicated that Anotheca is phyletically a member of the subfamily Hylinae. Thus, its placement in the Amphignathodontinae was due to convergent morphological evolution in Anotheca to resemble the other genera of marsupial tree frogs.
