Type locality: Namibia, Oshikoto Region, Tsumeb District, Farm Uithoek.  
Reproductionoviparous 
TypesHolotype: TM 45097 (Fig. 117): Adult male; coll. G. Voigt, 29 April 1974. Paratypes: TM. 
DiagnosisDIAGNOSIS.—Snout-vent length to at least 42.9 mm (TM 85000). May be distinguished from all other members of the P. serval/weberi group by the combination of the following characters: snout blunt; rostral excluded from nostril; supranasals in narrow anterior contact; scales on dorsum of head weakly conical, those on snout much larger than those of interorbital region; interorbital and parietal granules intermixed with scattered, conical tubercles, each smaller than scales of snout; dorsal scalation heterogeneous, consisting of small conical scales interspersed with larger strongly keeled to mucronate tubercles; tubercles becoming conical on flanks; tubercles in 18 rows; thighs bearing very large conical tubercles; toes moderately long, toe pads relatively narrow; five undivided lamellae beneath digit IVof pes; tail (partly regenerated) to at least 102% of SVL, annulate, bearing whorls of large, pointed, strongly keeled tubercles, narrowly separated from each other; cloacal spurs very large bearing dorsally-directed pointed scales with concave surfaces; adult pattern of three pale bands (nape, just posterior to adpressed elbow, and posterior trunk, anterior to lumbar region) separating broader areas of grayish-brown with darker brown edges—pattern may be obscured and appear as 5–6 dark brown bands on a pale background (Figs. 117–118 in Bauer et al. 2006); juvenile pattern as adult, with three pale bands (Fig. 118).
 
CommentHABITAT: mountain savanna, karstveld, broadleaf savanna: rocky dolerite mountains, rock cracks.

Abundance: only known from its original description (Meiri et al. 2017). 
EtymologyETYMOLOGY.—Named for the Otaviberge or Otavi Highlands, a low range of dolerite hills in northeastern Namibia to which this species appears to endemic.
