Tail flattened cylindrical without distinct segmentation (oceanica with distinct segmentation) and with a ventrolateral bor- der of small elongate scales; distinct digital pads with 8–9 subdigital lamellae (12-16 in oceanica) on fourth digit of hindfoot (modified after Zug 2013: plate 5).
Comment	Synonymy: Gehyra insulensis has been synonymized with G. mutilata by many previous authors but more recently accepted as a valid species. Sometimes cited as GIRARD 1857.
