Rhacodactylus leachianus henkeli — SCHÖNECKER & SCHÖNECKER 2009 
DistributionNew Caledonia; Isle of Pine; Belep Isles (?)

henkeli: restricted to the Ile des Pins south off New Caledonia

Type locality: not given (fide WERMUTH 1965).  
Reproductionoviparous 
TypesHolotype: MNHN-RA 6687
Holotype: SMF 75976 [henkeli]
Holotype: lost, was MHNG 769.94, MLI* [aubrianus] 
Diagnosis 
CommentSynonymy: The only known specimen of Rhacodactylus leachianus aubrianus were destroyed in 197. The description of Bocage (1873) is inadequate to assess the potential validity of this taxon. The validity of henkeli has been questioned by SEIPP (1996; thesis) and GOOD et al. (1997).

Type species: Ascalabotes leachianus Cuvier, 1829 is the type species of the genus Rhacodactylus Fitzinger, 1843.

Abundance: Widespread but not very common. Highly priced as pet, e.g. in Korea.

Caudal autotomy: Bauer & Russell surveyed autotomy in carphodactylid geckos, including Rhacodactylus.

Variation: This is a fairly variable species. See Cemelli 201 and Cemelli & Fast 201 for a series of photographs that illustrate color variation.
