). Overall grey-brown colouration with distinct darker brown markings. Forelimbs dorsally grey-brown with one distinct darker brown cross-band on upper arm and three brown cross-bands on lower arm and hand, hands speckled. Finger and toe tips are grey-cream and first and second toes are lighter in colour than the other toes. Flanks with the same colour of the dorsum but with less distinct darker patches. Overall the darker dorsal colour fades into the whitish ventral colour. Nostril distinctly surrounded by a cream thin line; lateral head same colour as dorsum. Ventral colouration in the preserved specimen is more contrasted than in the living specimen. Throat, belly and thighs dirty white, ventral shanks slightly darker than thighs, chest flecked with a few distinct and scattered grey-brownish markings; sole of foot brown. Colouration of limbs is overall similar to the dorsum, although it has less defined markings. Hindlimbs with five dark brown cross-bands on femur, four on tibia, four on tarsus and foot; dorsal foot grey-brown with four slightly defined perpendicular darker brown crossbands.

If suitable habitat is considered to encompass all areas within the polygon drawn among the known localities (likely an over-estimate), then the EOO (extent of occurrence) totals 563 km2. If plots with a scale of 2 km2 are used to estimate AOO (area of occupancy), then this species occurs within 36 km2 of habitat.
