Long-hidden in Thaxter's treasure trove: Laboulbenia camerunensis sp nov parasitic on African Curculionidae

A new species, Laboulbenia camerunensis, parasitic on Curculio sp. from Cameroon, is described from a historical slide prepared by Roland Thaxter. It is the seventh species to be described from the family Curculionidae worldwide and the first from the African continent. The species is recognized by the characteristic outer appendage. The latter consists of two superimposed hyaline cells, separated by a black constricted septum, the suprabasal cell giving rise to two branches, the inner of which is simple and hyaline, and the outer tinged with brown. A second blackish constricted septum is found at the base of this outermost branch. Description, illustrations, and comparison to other species are given.
