Jacobsen, 29 October 1980; TM 58031–58032, collector R. E. Newbery, 5 June 1984; TM 58118, collector R. E. Newbery, 21 November 1984; TM 62907–62909, collector R. E. Newbery, 21 February 1985; TM 64021, collector R. E. Newbery, 1 June 1984.
Etymology. The species name refers to the local name for Mariepskop, the type locality.
Diagnosis. A large Afroedura (to 63 mm SVL) differing from all other congeners by the following combination of characters: two pairs of enlarged subdigital lamellae per digit; a single internasal granule between nasorostrals; tail not obviously verticillate, with 4–5 subcaudal rows and 6–8 supracaudal rows per verticil; dorsal scales smooth, in 96–108 rows at midbody; a single internasal scale; 11–13 precloacal pores in males.
Description. (based on holotype TM 81262) Adult male; SVL 57.0 mm; tail 61.0 mm (partly regenerated); mass in life 3.3 g. Head and body dorso-ventally depressed. Head oval and wider than neck, body broad and limbs relatively short, digits stout. Rostral twice as broad as high, more or less octagonal; nostril pierced between rostral, first upper labial and three nasal scales; nasorostrals separated by a single large granular scale. Scales on snout rounded to conical, larger than those on crown. Scales between nasals and anterior margin of eye 12, and from eye to ear 24. Four supraciliary spines at posterodorsal corner of eye. Supralabials 10. Mental wider than deep; postmentals three; infralabials eight.
Dorsals smooth, uniform, each scale raised posteriorly and juxtaposed; scales at midbody 107. Ventral scales smooth, flattened and imbricate. Digits stout with two pairs of enlarged scansors and five enlarged inferomedian scales under fourth toe, not reaching the base. Precloacal pores 13, arranged in a continuous ‘V’-shaped pattern. Tail regenerated and constricted at base. Two postcloacal spurs on either side of tail base.
Color. Olive-brown to olive-gray above with variable blackish crossbars extending from occiput to sacrum. Crown of head variably marked, filigreed to reticulate. Interstices between bars are reticulate laterally. Limbs barred or variegated. Tail with approximately 10 black bars, becoming more irregular and diffuse posteriorly. Chin, throat, chest and abdomen whitish. Underside of tail grayish brown, faintly barred.
Variation. Paratypes and other specimens agree with the holotype in most features of scalation (Table 4). Endolymphatic sacs distended in adult female paratype TM 81260. Scales between nasals and eye 11–13, from eye to ear 20–23. Supraciliary spines 2–4. Rostral and mental scales variable in relative proportion and shape. Postmentals 2–3. Supralabials 9–10, infralabials 7–8.
Midbody scale rows 96–108. Inferomedian scales under the fourth toe 5–8. Precloacal pores in male paratypes 11–13, females lacking pores. Postcloacal spurs 2–3, rarely four. Original tails 52.1–53.9% of total length and tapered. Tail with 6–8 (mostly seven) dorsal and four (rarely five) ventral scale rows per indistinct verticil. Supracaudals subimbricate with a rounded to pointed posterior margin; subcaudals broad and imbricate.Caudal autotomy evident in 76.3 % of individuals.
Distribution. Restricted to the slopes of Mariepskop and God’s Window area of the Eastern Escarpment, in apparently two disjunct populations (Fig. 6). Occurrence in the latter area is verified by a photo voucher.
Natural history. Usually associated with rocky outcrops on west-facing slopes of Mariepskop, frequently in the partial shade of pine plantations but also found on outcrops of Black Reef quartzites on top of the escarpment in the shade of indigenous montane forest. Preferred retreats include crevices under flakes of exfoliating rock and dark overhangs of large boulders. Found in Ohrigstad Mountain Bushveld (SVcb 26) and Northern Escarpment Quartzitic Sourveld (GM 23) (Mucina & Rutherford 2006) at elevations of 1700–1900 m a.s.l.

…… continued on the next page Two eggs are laid at a time during August–October. They are soft when laid, adhering to the rock and hardening, as has been reported for A. halli (Power 1939). The eggs measure 9.5–10.9 x 7.8–9.3 mm and take approximately two months to hatch. Neonates measure 23.0 mm SVL, 21.0 mm TailL, with a mass of 0.25-0.30 g.
Remarks. Afroedura maripi sp. nov. was included by Jacobsen (1990, 1992a, 1997) in his A. pondolia complex, but our molecular results suggest that while other members of this proposed complex— A. marleyi, A. pongola sp. nov., and presumably A. rondavelica sp. nov. (also unsampled genetically), as well as A. maripi sp. nov. —do form a monophyletic group, referred to as the A. marleyi group, A. pondolia is only distantly related. It may be distinguished from A. pongola sp. nov. and especially A. marleyi on the basis of its greater number of midbody scale rows (mean of 102.56 versus 98.22 and 88.77, respectively) and larger size (maximum SVL 63 mm versus 40 mm and 36 mm, respectively) and has substantially fewer precloacal pores than A. pongola sp. nov. (11–13 versus 21–23). It also has significantly more supralabial scales than A. marleyi (p <0.001, t37 d.f.).It is larger (60 mm versus 55 mm maximum SVL) and has more precloacal pores (11–13 versus 7–9) than A. rondavelica sp. nov.
