First record of the genus Anisocentropus McLachlan (Trichoptera: Calamoceratidae) from Nigeria, with description of mature larva

Abstract

The genus Anisocentropus is reported for the first time from Nigeria and description is given of the mature larvae of an unknown species from Ile-Ife, southwestern Nigeria. The species closely resembles A. usambarensis Ulmer known from Tanzania in east Africa but differs in the shape of the anterior ventral apotome of the head and the possession of spines on the pronotum. This difference suggests the existence of a species separate from A. usambarensis and other species in the Afrotropical region. Information on the morphological features of adults is necessary to confirm this.
