Maladera mutabilis is a species of beetle of the family Scarabaeidae. It is found in Indonesia (Java) and India (Tamil Nadu).
Adults reach a length of about 5.6âÂÂ6.4 mm. They have a reddish-brown, oval body. The upper surface is mostly dull and glabrous, except for some hairs on the head and elytra and the lateral cilia of the pronotum and elytra.
Some works incorrectly consider Olivier (1789) as the author of this species or even interpreted M. mutabilis (Olivier) as a homonym of M. mutabilis (Fabriciues). However, no syntypes of Olivier's M. mutabilis have been located and it is very likely that Melolontha mutabilis (Olivier, 1789) is a nomen nudum.
