Van Kampen, 1919, Bijdr. Dierkd., 21: 54, thought that Cophixalus geislerorum might be an Oreophryne but declined to make the combination. Zweifel, Menzies, and Price, 2003, Am. Mus. Novit., 3415: 11, noted that this species had been confused in the literature with Oreophryne biroi in the literature. Menzies, 2006, Frogs New Guinea & Solomon Is.: 208-209, provided a brief account. Kraus, 2013, Herpetol. Rev., 44: 278, provided a record from Mount Victory, Northern Province, Papua New Guinea.
