TypesHolotype: NMZB 10032 
DiagnosisDiagnosis: Closely related to S. bidigittatus FitzSimons, but differing in its more elongated snout, shorter rostral, longer frontal, presence of a forelimb bud (absent in bidigittatus) and longer hind limb, with inner toe much longer than outer, with 6-7 subdigital lamellae (inner toe slightly longer than outer in bidigittatus, with 2-3 subdigital lamellae), also in having 18 scale rows at midbody (usually 20 in bidigittatus) and only 83-84 ventral scales between mental shield and cloaca (102-105 in two bidigittatus from Kruger National Park), tail slightly shorter than snout-vent length (slightly longer in bidigittatus). Colouration darker, almost black dorsally, with pale dorsolateral line bisecting scale row 2, counting from the vertebral line (pale dorsolateral stripes broad, covering lower half of scale row 2 and upper half of 3 in bidigittatus).

CommentLimb morphology: This species lost its forelimb entirely and retains only two digits on the hind limb.

Group: Belongs to the didactyle S. bidigittatus group.

Abundance: only known from its original description (Meiri et al. 2017). This is one of the species called 'lost' and 'rediscovered' by Lindken et al. 2024. 
EtymologyThis species is named for Paul Dutton in recognition of his major contributions to our knowledge of the fauna and flora of the Bazaruto Archipelago.
