Vladimir M. Gnezdilov, Jérôme CONSTANT
A new species of the genus Orthophana Melichar, 1923, O. tamdaoina sp. nov., representing a new subgenus, Eupharos subgen. nov., is described from the Tam Dao National Park in northern Vietnam. Diagnostic characters are provided in a form of a key to differentiate the new species and the new subgenus from the type species, O. spinata Melichar, 1923. The following nomenclatural changes are proposed: Lollius gratiosus Melichar, 1906 is transferred to the genus Epitonga Fennah, 1954 to become Epitonga gratiosa (Melichar, 1906) comb. nov. and Issus lineolatus Walker, 1862 to the genus Cotylana Fennah, 1954 to become Cotylana lineolata (Walker, 1862) comb. nov.
