“…Further examination of the slides revealed yet another undescribed species of Laboulbenia, on Curculio sp., a member of the family Curculionidae (Wang 2014). Although reported by his contemporary Spegazzini (1917) from Argentina and more recently by Sugiyama & Majewski (1987) and Rossi et al (2015), this is the only material studied by Thaxter that occurs on a member of the 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.

from Croatia and Slovenia (and the first undoubtful record from Slovakia). Laboulbenia flagellata was found on 11 host species in the genera Agonum, Oxypselaphus, Patrobus, Platynus, and Pterostichus. Using this abundant material, we performed morphometrics to test the hypothesis that L. flagellata is a species complex. Specimens cannot be separated based on host genus (Agonum, Pterostichus). One parameter is significant between Pterostichus mutus and each of the 4 Agonum species after applying a strong Bonferroni P-value correction: H1T, the ratio of height of cell I (HC1) to total thallus length (TTL). In addition, we collected fresh material to be able to add a molecular phylogenetic component to test said hypothesis. We generated ITS and nrLSU ribosomal sequences of several species of Laboulbenia, including isolates of L. flagellata from multiple hosts. Phylogenetic inference of the concatenated dataset shows that L. flagellata isolates from 3 host species form 2 distinct clades, providing support for our hypothesis. We also show that L. coneglianensis is separate from L. flagellata, unequivocally ending a long-standing taxonomic debate. Finally, examination of Roland Thaxter's 1891-1932 slides led to the designation of lectotypes for L. macrothecia, L. terminalis, and P. geminata.
