Definition (genus). Ramigekko is distinguishable from all other geckos based on the following combination of characters: size large (77 mm max. SVL), with a moderately flattened head and body, and round, tapering tail. Digits are free and bear a single pair of dilated terminal adhesive pads (‘leaf toes’); claws are present on all digits. Dorsal scala- tion consists of enlarged smooth tubercles interspersed with smaller granules. Preanal pores are absent; one cloa- cal spur is present. The eye bears a vertical pupil with cre- nate margins. The skull displays no co-ossification with the overlying skin. Nasals are fused; frontal single; parie- tals partly fused; stapes imperforate; 14 scleral ossicles; 13 premaxillary and fewer than 40 dentary teeth; hyoid with second ceratobranchial cartilages. There are 26 pre- sacral vertebrae and one pair of cloacal bones. The pha- langeal formula is 2-3-4-5-3 (manus)/2-3-4-5-4 (pes); paraphalangeal elements are absent, but extraphalangeal digital ossifications are present.
Ramigekko swartbergensis exhibits the following non- homoplastic apomorphic characters: suborbital fenestra oval, almost chicken egg shaped (23-0); posterior edge of the ascending nasal process transverse (41-3, Fig. 13); border of frontal inflected along posterior portion of pre- frontal seam (131-1, Fig. 13); frontal participates in the orbitonasal foramen (148-1); coronoid participates in the labial border of the anterior surangular foramen (317-1, Fig. 18); number of maxillary tooth loci between 35 and 39 (370-7); dentary tooth row extends to the posterior half of the jaw (377-1); teeth narrowly spaced with crowns contacting for much of their height, ctenodont (387-2, Fig. 18).
Ramigekko and Cryptactites are unique among leaf- toed gecko genera in having partial fusion of the parietals (Figs 12–13). Ramigekko is also readily distinguished from all other African leaf-toed gecko genera based on its large body size and unkeeled tubercular dorsal scalation [Heinicke et al. 2014].
|Etymology||“The name is a combination of the Latin noun ramus, meaning branch, and gekko, a latinization of a Malay word said to imitate the vocalizations of geckos (subsequently applied to the lizards themselves). We apply the name in recognition of Professor William R. Branch, curator emeritus of herpetology at Bayworld (formerly Port Elizabeth Museum), in honour of his recent retirement and in recognition of his many contributions to the systematic herpetology of southern Africa. The gender is masculine.”|
