The Clidicini (Coleoptera: Scydmaenidae: Mastiginae), comprised of four genera: Clidicus Laporte (12 spp), Leptochromus Motschulsky (5 spp, including 1 sp, Chiapas amber), Papusus Casey (9 spp), and Palaeoleptochromus O'Keefe (1 sp., Cretaceous amber), is a monophyletic group with the following topology: (Clidicus (Papusus (Palaeoleptochromus, Leptochromus))), based on a cladistic analysis (43 steps, CI=0.95, RI=0.92). The only larva known for any species of the tribe, for Clidicus abbotensis O'Keefe, is described. Comparative morphological structures, male and female genitalia, and antennae are illustrated. Basic biology of the extant genera and a biogeographic scenario of the tribe are discussed.
