Long-hidden in Thaxter's treasure trove: <I>Laboulbenia</I> <I>camerunensis</I> sp. nov. parasitic on African <I>Curculionidae</I>

Abstract

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.

“…Perithecium 91-120 × 24-32 µm, elongate, nearly symmetrical except for the anteriorly curved apex, with prominent and rounded posterior lips, both of which subtend a conspicuous papilla; posterior pre-ostiolar spot very conspicuous, black, opaque. , 2016, Wang et al 2016b). Laboulbenia has a very wide host range, however L. coccinellidicola is the first species on Coccinellidae.…”
