abstract
Four new species of the genus Helina Robineau-Desvoidy are described from Madagascar as Helina andasiba spec. nov., Helina mantada spec. nov., Helina ranoma spec. nov. and Helina fianara spec. nov. The latter was previously incorrectly identified as Helina insignis. The species H. insignis is only known from Madagascar and it is recommended, that it is synonymized with Helina cyanea, another species endemic to Madagascar. There are now nine species of the genus that occur in Madagascar. They are compared in a revised identification key to the Madagascan Helina species.
