DistributionNE Tanzania (Eastern Province)

Type locality: Kimboza Forest, Eastern Province, Tanzania, 350 m  
Reproductionoviparous 
TypesHolotype: NMK (formerly Coryndon Museum, Nairobi), also given as MCZ 51500 
DiagnosisDiagnosis: In its scalation apparently indistinguishable from typical picturatas, occurring in the surrounding savannah region, but strikingly different in coloration. which may be defined as follows:
Male williamsi. Above entire upper surfaces brilliant turquoise blue; from nostril through eye to nape is a broad black streak; three or four scales above this a sharply defined black chevron, one or two scales in width, extendy back to the nape except for a two- scale-wide interruption above each orbit; flanks finely speckled with black; limbs almost immaculate. Below, chin and throat turquolse blue overlald by an Ill-deñned black chevron on the mental and along the base of the labials; four parallel, broad, some- times coalescing, black streaks extend from chin to neck; forelimbs, chest, belly, and base of tail pale orange, deepening to orange towards the sides and on the hind limbs, rest of tail bluish grey.
Male picturatus. Above, head and shoulders bright mustard-yellow, speckled and streaked with brownish black; body, limbs and tall blue-grey, uniform or flecked with brownish black such markings sometimes coalescing to form lines.

CommentConservation: FLECKS et al. (2012) suspect that commercial collection of this species for the pet trade is pushing this species to the brink of extinction.

Abundance: only known from the type locality (Meiri et al. 2017). 
EtymologyNamed after J.G. Williams, the collector of the type.
