Hybosoridae, sometimes known as the scavenger scarab beetles, is a family of scarabaeiform beetles. The 210 species in 33 genera occur widely in the tropics, but little is known of their biology. Hybosorids are small, 5-7 mm in length and oval in shape. Color ranges from a glossy light brown to black. They are distinctive for their large mandibles and labrum, and their 10-segmented antennae, in which the 8th antennomore of the club is deeply grooved and occupied by the 9th and 10th antennomeres. The legs have prominent spurs. * Hybosorus roei
