Rhacodactylus trachycephalus

Môrô Islet Giant Gecko



1878 Chameleonurus trachycephalus Boulenger
Rhacodactylus trachycephalus Bauer, Jackman, Sadlier & Whitaker 2012

Remarks: Previously regarded as a synonym of trachyrhynchus (e.g., Bauer 1994; Cunkelman 2005). Revalidated by Bauer, Jackman, Sadlier & Whitaker (2012). Although originally described from Île des Pins, continued presence in this island needs confirmation (Bauer, Jackman, Sadlier & Whitaker 2012).
Distribution: New Caledonia (Moro Islet).

Rhacodactylus trachyrhynchus

Rough-snouted Giant Gecko


Rusnudet Kæmpegekko

1873 Rhacodactylus trachyrhynchus Bocage

Remarks: Previously included trachycephalus. Now restricted to the main island, Grande Terre. Records from Île des Pins refer to trachycephalus (see remarks under that species).
