The rough-nosed horned lizard (Ceratophora aspera) is a lizard from Sri Lanka in lowland dipterocarp forests and secondary forests in the wet zone. It is distinguished from all the other Ceratophora species by the presence of a complex rostral appendage, comprising more scales than rostral scale alone. The lateral body scales are small and more or less regular shape.
