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.

An X-shaped dorsal ridge at back of head. Tympanum hidden under the skin. A weak dorso-nuchal crest confined to the neck region. Gular fold absent. Body slightly compressed. Lamellae under fourth toe counts 11-14. Males are dark brown or brick-red dorsally and on the flanks. Females may be similar to males in coloration and can be lighter, with some individuals have four diamond-shaped marks and black spots or longitudinal lines on dorsum.
