Crenadactylus Dixon & Kluge, 1964

Type species. Diplodactylus ocellatus (= Crenadactylus ocellatus ) Gray, 1845 by original designation.

Diagnosis. Based on Dixon & Kluge (1964). Species within the genus Crenadactylus are small (max SVL 35 mm) geckos differing from all other gekkonids by a combination of the following external morphological characteristics; digits with enlarged subdigital lamellae, terminal phalangeal elements forked and claws absent from all digits; outer margins of anterior portion of frontal notched to receive posterior projection of paired nasals. Internal morphological diagnostics include palatines short and broad, atlas fused dorsally; stapes imperforate (stapedial foramen absent); two pairs of sternal ribs, one or two pairs of mesosternal ribs; 28 sacral and presacral vertebrate; sacral diapophyses overlapping and fused (not fused in juveniles); in adults anterior tip of mesoscapula fused to precoracoid process at its union with precoracoid; interclavicle dagger-shaped; fingers 5; toes 5; phalangeal formula of manus 2-3-4-5-3, pes 2-3-4-5-4; 24–26 scleral ossicles; 13 or 15 premaxillary teeth; 29–31 maxillary teeth; 33–37 mandibular teeth; cloacal bones present in males ( Dixon & Kluge 1964).

Etymology. A combination of the Latin word crena meaning ‘notch’ and Greek word daktylos meaning ‘finger’ in reference to the forked terminal phalanges.
