TM 81266, adult female, Farm Waterval 601 LQ, 23 ° 53 ' S, 27 ° 39 ' E, Waterberg District (2327 DC), Limpopo Province, collectors N. H. G. Jacobsen & R. E. Newbery, 20 January 1987. Paratypes. TM 81267, 81269, 81273, Farm Fancy 556 LQ, Waterberg District, Limpopo Province (2327 DC), collectors N. H. G. Jacobsen & R. E. Newbery, 22 January 1987. TM 81268, 81270, Farm Fourieskloof 557 LQ, Waterberg District, Limpopo Province (2327 DC), collector R. E. Newbery, 26 September 1979; TM 81271–81272, same data as for holotype. Etymology. The specific epithet refers to the Waterberg massif, Limpopo Province, to which the species is endemic. Diagnosis. A small Afroedura (maximum SVL 46 mm) differing from all other congeners by the following combination of characters: two pairs of enlarged subdigital lamellae per digit; tail moderately verticillate (semiverticillate) and flattened near base, with four subcaudal rows and 7 supracaudal rows per verticil; dorsal scales smooth, 92–99 scale rows at midbody; internasal scales absent; 4–7 precloacal pores in males. Description. (based on holotype TM 81266) Adult female, SVL 44.0 mm; TailL 53.0 mm; mass before preservation 2.2 g. A small to medium-sized, dorsoventrally depressed gecko. Head oval, neck thick, almost as wide as head. Rostral approximately 2.5 times wider than high; nostril pierced between rostral, first supralabial and three nasals; nasorostrals large and in contact behind rostral. Scales on snout rounded but not flattened, decreasing in size posteriorly to crown of head; 9–10 granular scales between nasals and eye and 18 from eye to ear; 3–4 supraciliary spines; supralabials 11. Mental longer than broad and not wedge-shaped; postmentals two; infralabials nine. Dorsal scales smooth, juxtaposed, uniform and rounded, becoming larger and oblique laterally. Midbody scales in 101 rows. Ventral scales hexagonal to rounded, smooth and juxtaposed. Hindlimbs robust, feet moderately enlarged. Digits with two pairs of enlarged scansors and 4 th toe with six enlarged inferomedian scales. Precloacal pores absent. Tail semi-verticillate, flattened and tapered, constricted at base and widening at the beginning of the first verticil. Caudal scales arranged in verticils with seven dorsal and four ventral rows. Supracaudals subimbricate, more or less square with a rounded posterior margin; subcaudals imbricate wider than or as wide as long. Two postcloacal spurs on either side of tail base. Color. Brown to pale brown above with 6–7 wavy dark brown to blackish crossbands extending from the occiput to the sacrum. Posterior margin of crossbands darker and with white spots in indentations. A vertebral row of white spots is most pronounced. Crown of head marbled with dark brown and a dark brown stripe extending from the nostril through the eye, merging into the occipital crossbar. Limbs striped with dark brown, with interstices spotted and a reticulate pattern on the thighs. Venter white to whitish pink. Tail with seven crossbands at regular intervals. Underside of tail brown with incomplete pale crossbars. Variation. Paratypes and other specimens agree with the holotype in most features of scalation (Table 4). Scales from eye to ear 16–18. Mental in some specimens only as long as wide. Supralabials 8–11. Infralabials 7–9. Midbody scale rows 92–99. Eight enlarged inferomedian scales under 4 th toe in TM 81272. Precloacal pores in males in continuous series of 4–7. 0–3 postcloacal spurs on either side of tail base. Original tails 50.0– 56.4 % of total length. Supracaudal scales in 6–7 (rarely 8) rows per tail whorl. 33 % of specimens have regenerated tails (n= 6). Distribution. Endemic to the western Waterberg massif, Limpopo Province (Fig. 6). Natural history. Afroedura waterbergensis sp. nov. is a rupicolous gecko found in crevices between rocks on rocky outcrops and cliff faces of Waterberg sandstone. It inhabits both vertical and horizontal dry crevices. It has only been observed in Waterberg Mountain Bushveld (SVcb 17) (Mucina & Rutherford 2006) at an elevation of 1000 m a.s.l. Remarks. Afroedura waterbergensis sp. nov. is the westernmost member of its genus in Limpopo Province. It may be more widespread along the Waterberg than the current records indicate. It is a member of the A. langi complex and may be easily distinguished from all other members of this clade on the basis of its low number of precloacal pores (see Table 4).Published as part of Jacobsen, Niels H.
