A new primitive helicopsyche from Madagascar (Trichoptera: Helicopsychidae), with phylogenetic analysis of afrotropical species

Abstract

A new species of the subgenus Petrotrichia Ulmer, 1910 within the genus Helicopsyche von Siebold, 1856 (Trichoptera), Helicopsyche anomana sp.n. is described. A cladistic analysis was executed to establish its phylogenetical relationship to other Petrotrichia species. The results of the analysis shows that the species is the sister species to Helicopsyche giboni Johanson, 1997, and together they form a basal clade within the Afrotropical Helicopsyche and also within the Helicopsychidae.
