Description
The dorsum of P. madurensis is iridescent purplish brown. The ventrals and the scales in the two adjoining rows on both sides are white in the center, with purplish brown borders.
The longest of Beddome's type specimens measures 35 cm (13+3⁄4 in) in total length (including tail).
The dorsal scales are in 15 rows at midbody (in 17 rows behind the head). The ventrals number 158-175; and the subcaudals, 10–15.
P. madurensis is very similar to P. trilineatus, except the head shields are shorter, and the supraocular is not longer than the prefrontal. Diameter of body 38–42 times in total length.[3]

Two subspecies are recognized, including the nominate race.
- Platyplectrurus madurensis madurensis Beddome, 1877
- Platyplectrurus madurensis ruhanae Deraniyagala, 1954[2][4]
The subspecific name, ruhanae, refers to the Ancient Sri Lankan Kingdom of Ruhuna (also spelled Ruhana).[5] Some sources consider it to be a separate species.[1]
