Maladera beata is a species of beetle of the family Scarabaeidae. It is found in India (Tamil Nadu).
Adults reach a length of about 7.3 mm. They have a reddish brown, oblong-oval body, with the elytra slightly lighter and the antennae yellowish. The dorsal surface is dull and glabrous, except for a few short setae on sides of the elytra.
The locality labels of the lectotype give a type locality of Sierra Leone, but researchers conclude that this must be erroneous, since all relatives of this species live in Asia and recent records are all from southern India.
