A very similar species is Cerynea contentaria (Walker, 1861), which I have struggled to separate reliably from Cerynea punctilinealis.

Cerynea contentaria at Roger Kendrick PhD Plate 41/17.
Cerynea contentaria MON Part 5, Pl. 136/11. This may be an error in ID and may be Cerynea punctilinealis. MOB lists both species as valid with distributions as under:
Cerynea contentaria Walker (Part 13, p. 89). Endemic. (Lowland). Borneo, Sri Lanka
Cerynea punctilinealis Walker (Part 13, p. 90). Indo-Australian tropics to Solomons. Lowland forest and disturbed habitats.
There are many Cerynea species on MOI which maybe Cerynea punctilinealis or Cerynea contentaria. One difference that I can make out is that the latter has much more prominent black marginal spotting on the forewing. It is likely that Cerynea contentaria is more of a S. Indian species, while Cerynea punctilinealis is found throughout India.
