Abstract
The two species originally described in the genus Iodocephalus Gagnep. are not congeneric. The species that was retained in the genus by Kitamura and stated as the type of the genus by Swart is reduced to synonymy under Camchaya Gagnep., and a new combination Camchaya gracilis (Gagnep.) S. Bunwong & H. Rob. is proposed. This species is reported for the first time from Thailand. A new genus, Iodocephalopsis S. Bunwong & H. Rob., is established for the second species originally placed in Iodocephalus, and both Iodocephalus glandulosus Kerr and Camchaya eberhardtii (Gagnep.) Kitam. are placed in synonymy under the newly combined Iodocephalopsis eberhardtii (Gagnep.) S. Bunwong & H. Rob.
