DistributionPhilippines (Palawan Island)

Type locality: Thumb Peak, Palawan Island, Philippines.  
Reproductionoviparous (phylogenetic imputation, fide Zimin et al. 2022) 
TypesHolotype: MCZ 44162 (collected by Edward H. Taylor in 1923 but never formally described by him). 
DiagnosisDiagnosis: S. victoria differs from S. kinabaluensis in nearly every one of the nine characters listed in Table 13. It differs from S. murudensis in : (1) the number of anterior loreals; (2) the smaller prefrontal which are separated or narrowly in contact; and (3) the smaller number of large supraoculars (4 instead of 5). From S. mindanensis, to which it is probably most closely related, it differs in (1) the larger eye relative to snout length or head breadth (Table 1) ; and (2) the color pattern. S. victoria has a more uniform dorsal pattern, lacking the blackish mottling or exhibiting only a vertebral row of dark bars, and the dark band on the upper lateral surface is much more uniform and even-margined dorsally. (Brown & Alcala 1980)
