Megophrys montana

The Asian horned frog, also called the Javan horned frog or Malayan leaf frog, is a frog found in Java and possibly Sumatra, so its Malaysian listing should be checked. It is a relatively large frog: males can reach 92 mm in snout–vent length and females 111 mm, and the upper eyelids have horn-like elongations (Wikipedia, general species account).
