Plaesius javanus, the Jepson's beetle, is a species of clown beetles belonging to the family Histeridae.

[1] Plaesius javanus can reach a length of about 14–15 millimetres (0.55–0.59 in).

These beetles have a glossy black body, with long and curved jaws and short antennae.

[2][3] These predatory histerid beetles have been introduced in some countries for the control of the banana weevil borer (Cosmopolites sordidus).
