Additionally, this distinct lineage is biogeographically circumscribed on the deepwater islands of Mindoro and Semirara.

Ventral coloration is moderately variable. The characteristic gular blotches or spots are present in all specimens, though the number and relative size of blotches is somewhat reduced in four specimens (KU 305161, 308403, 335742, 335743). Two specimens (KU 305151, 305163) exhibit much larger and more conspicuous gular spots. Ventral trunk coloration is less variable, with only three specimens (KU 305161, 308403, 308437) exhibiting reduced transverse dark bands, which generally fail to converge medially. Ventral coloration of the limbs is nearly identical among specimens, with only slight variation in the appearance of black color encroaching on the lateral margins of both fore- and hindlimbs, but generally appearing as partial transverse bands.
