Rather than attempt to match the excellence of the key to all of the recognized species prepared by Holthuis (1950a: 105-111), we have restricted our attention to the Philippine and Indonesian species, and even those have been embarrassingly equivocal. Because only full-grown males of many of the species can be reliably identified from preserved material and because several of the names currently available were based on females or younger than full-grown males, final determinations of many of the taxa must await new collections from the type localities and, especially, the study of fresh or frozen specimens that may display diagnostic color patterns.
