On this dark stripe vertical series of white dots alternating with darker spots, these often somewhat irregular. Scale rows around body, 28; a transparent eye disk present; 70 scales on back between nuchals and a point above vent; snout to arm insertion length contained in axilla to groin length 2½ times; adpressed limbs separated by a distance equal to one and a half to one and two thirds length of arm.

Comment	Abundance: only known from the type locality (Meiri et al. 2017). This is one of the species called 'lost' and 'rediscovered' by Lindken et al. 2024.
Etymology	Not given by Taylor 1950, but possibly named after Vijaya (Singha), the first of the approximately 189 monarchs of Sri Lanka.
