The Aclopinae are a small group of scarabaeoid beetles found in southeast Asia, Australia and South America, characterised by the possession in males of remarkably long hind tarsi (Cassis & Weir 1992).

Characters (from Cassis & Weir 1992): Medium-sized (7–21 mm), often bicoloured black and brown, somewhat tapered towards rear of body. Labrum and mandibles exposed; elytra separately rounded, lacking narrow membranous margin; tarsal claws equal; abdomen very hairy; male hind tarsi very long, three or four times as long as tibiae.
