Abstract
The previously monotypic genus Tritonus Mulsant is revised. Six new species are described from Madagascar, from which the genus is also recorded for the first time: T. complanatus sp.n., T. crenulatus sp.n., T. madagascarensis sp.n., T. riambavy sp.n., T. riana, sp.n., and T. steineri sp.n. New records for the previously described and Mauritian-endemic species Tritonus cribratus (Mulsant) are given. All known species occur in hygropetric habitats, consistent with the biology of other members of the Oocyclus-genus group of the tribe Laccobiini to which Tritonus belongs. A key to species, aedeagal illustrations, and scanning electron micrographs of diagnostic characters are provided.References
