Platymantis guentiieri is rediagnosed. Four species, previously confused with guentheri, (P. rabori, P. negrosensis, P. luzonensis, and P. banahao) are described. Received March 14, 1996. Accepted May 30, 1996. In a recent paper (Brown et al. 1997) three species-groups (assemblages) of Philippine Platymantis were diagnosed, based on different combinations of digital characters. In the same paper, species of the hazelae group were revised. For convenience those diagnoses are briefly restated. The hazelae Group. --This Group is diagnosed by the following combination of char-acters: (1) terminal phalanx a wide "T"; (2) disks of fingers, except first, broadly dilated; (3) first finger much shorter than second, not reaching beyond midpoint between subarticular tubercle and disk; (4) digits proximal to disks much broader than deep, the result of wide dermal flanges; (5) subarticular tubercles large, round, and only moderately protruding; (6) toe disks smaller than finger disks. The guentheri Group. — ( 1 ) terminal phalanx a moderate to wide "T"; (2) disks of fingers, except first; moderately to broadly dilated; (3) first finger shorter than second, reaching as far as base of disk for some species; (4) digits proximal to disks about as deep as broad, the result of narrow, dermal flanges; (5) subarticular tuber-Pi
