Comment

Most closely related to Rhacophorus bimaculatus and Rhacophorus cyanopunctatus according to the original publication; this rejected by Jiang, Jiang, Ren, Wu, and Li, 2019, Asian Herpetol. Res., 10: 6, who placed those species in Leptomantis and Rhacophorus orlovi squarely in Rhacophorus. Ziegler, Herrmann, and Köhler, 2002, Herpetol. Rev., 33: 146, discussed records in Vietnam. See comment regarding Leptomantis under Rhacophorus. Nguyen, Ho, and Nguyen, 2005, Checklist Amph. Rept. Vietnam: 40, provided specific localities for Vietnam and (p. 150) a photograph.
