Diagnosis. — A large (up to 142 mm from snout to vent), stoutly build gecko (Fig. 4) belonging to the genus Gehyra. Subdigital lamellae under the dilated portion of the toes are not longitudinally divided. toes of G. georgpotthasti n. sp. are webbed up to about half of their length. extensive dermal folds are present anterior of the forelimb and posterior of the hindlimb, spanning from shoulder to base of toe and from cloaca to base of toe, respectively. Gehyra oceanica has only slightly developed folds on limbs, which span directly between knee and elbow, and toes are only rudimentarily webbed. Furthermore, G. oceanica has fewer subdigital lamellae (max. 20, but usually less than 18 under 4th toe, compared to at least 18 in G. georgpotthasti n. sp.; see table 2). Maximum snout-vent length of G. oceanica is smaller; in a series of 241 adult specimens from French Polynesia the largest was 93 mm (Ineich 1987), the by far largest specimen in the ZFMK collection is a male from western Samoa of 96 mm, and Beckon (1992) mentions 102 mm as maxi- mum snout-vent length, whereas G. georgpotthasti n. sp. can grows up to 142 mm (see table 2). Gehyra oceanica has at least 9-10 dark bands on tail (versus 5 to 6 such bands in G. georgpotthasti n. sp.). Subcaudal scalation of G. georgpotthasti n. sp. consists of enlarged, plate-like scales arranged in a median row, whereas G. oceanica and G. marginata have subequal scales or multiple (two or three) median rows of slightly enlarged, nearly subequal scales. Gehyra marginata also differs in having a flattened rather than rounded tail in section and has distinct dermal folds posterior of the forelimb and anterior of the hindlimb, both are merged with a broad fold along trunk. Gehyra membranacruralis lacks dermal folds on forelimb. G. vorax differs in shape of postmentals (short vs elongated in G. georgpotthasti n. sp.) and postrostral scale numbers (up to two vs. two or more in G. georgpotthasti n. sp.). Morphological characters of G. georgpotthasti n. sp. and similar species are summarised in table 2 (FLECKS et al. 2012).
