| Abstract | A new Helicopsyche (H. kantilali n.sp.) is described from the Seychelles Is. I n t r o d u c t i o n . Six species of Trichoptera have long been known from the Seychelles Islands (ULMER 1910) including a species of Petrotrichia (P.palpalis ÜLMER). The latter is actually a Helicopsyche (and not as alleged by ULMER a Hydroptilid) and must be called Helicopsyche palpalis (ULMER). A second species was found by Expedition F. Starmühlner (1974) (as larvae and mature pupae) and by G. Marlier (1976) at all instars at several stations of the Island of Mane; the immature instars will be described elsewhere, the adult being described in the present paper. The new species is called Helicopsyche kantilali n.sp. in the honour of Mr. Kantilal Jiwan, keen naturalist and nature protectionist from Mahé, who was very helpful in organizing the last mentioned expedition.
