Palawaneuria, a new subgenus ofCompsoneuria and new species ofCompsoneuria andAfronurus (Ephemeroptera, Heptageniidae) from Palawan, Philippines

Abstract

A new subgenus and four new species of Heptageniidae are described from streams of the Philippine island of Palawan: Compsoneuria (Palawaneuria) cabayuganensis subgen. n., sp. n. (<, ,, <-SI, ,-SI ), Compsoneuria (s. str.) tagbanua sp. n. (<, ,, <-SI, nymph), Afronurus palawanensis sp. n. (<-Ny, <-SI) and Afronurus zerningi sp. n. (<Ny). The new subgenus shares with imagos of Compsoneuria (s. str.) markings of body, legs and wings and is separated from it by absence of apico-medial hooks and discal spines of penis lobes and by having brown-coloured wings in subimagos. The genus Compsoneuria Eaton is recorded the first time from the Philippines. The taxonomic status of Compsoneuria Eaton and the synonymization of Cinygmina Kimmins with Afronurus Lestage are discussed.
