Abstract
Rhacophorus notater Smith, 1924, described from a single juvenile, is regarded as conspecific with R. annamensis Smith, 1924. Both species were described from the same locality in Vietnam. Although the name R. notater appears before R. annamensis in the same publication, R. annamensis is more popular in name among herpetologists, and its biological details are better clarified than those of R. notater. Thus, I propose to treat R. notater as a junior synonym of R. annamensis.
