DistributionIvory Coast, Cameroon, Benin, Nigeria, Togo (elevation in Cameroon from 400 to 1700 m), Ghana

Type locality: Mukonje-Farm, Mundame, Cameroon.  
Reproductionoviparous 
TypesHolotype: lost, was ZSM 603/1911 (fide Franzen & Glaw 2007) 
DiagnosisDescription: Loveridge 1947: 84.

Diagnosis (genus). Small to moderate-sized (28–70 mm SVL) gekkonid geckos with long, slender limbs and digits and relatively short tails (typically < 110% SVL). Eyes small (< 21% HL), with round pupils, mostly laterally directed.
Dorsum of trunk usually with at least some smooth to weakly keeled dorsal tubercles (usually present over sacrum and pygal portion of tail, even if absent from trunk). Second phalanx of digit IV of the manus and pes lost, vestigial, or distinctly shorter than the corresponding third phalanx. Basal portions of digits expanded relative to the distal and bearing 1–7 enlarged plates or lamellae in a single series; distal phalanges slender and compressed. Males with precloacal pores in a single series of 6–16.
Ancylodactylus may be distinguished from Asian Cnemaspis by the features of the second phalanx noted above and by their more strongly expanded basal subdigital plates. From Cnemaspis sensu stricto (i.e., the Southeast Asian clade) Ancylodactylus is distinguished by its lack of lateral caudal furrows (present in all Cnemaspis sensu stricto except C. boulengeri Strauch and C. psychedelica Grismer, Ngo & Grismer; Grismer et al. 2014); variable presence of caudal tubercles distal to the pre-autotomic portion of the tail base (invariably present in Cnemaspis sensu stricto); eyes small to moderate in size and directed laterally (versus eyes large and directed somewhat forward and upward; Grismer et al. 2014); and original tail moderately robust, rarely greater than ~110% SVL (versus tail slender, frequently > 120% SVL). From South Asian Cnemaspis Ancylodactylus differs in eye size and orientation and in lacking the depressed “duckbill” morphology of the snout (seen in some South Asian and Southeast Asian) taxa. Ancylodactylus further differ from many South Asian Cnemaspis in lacking either spiny ventrolateral tubercles or highly heterogeneous dorsal scalation (independent of any rows of tuberculation). (Malonza & Bauer 2022). 
CommentHabitat: forested habitats (Perret 1986; Lawson 1993), montane savanna.

Type species: C. spinicollis is the type species of the genus Ancylodactylus MÜLLER 1907.
