Title: Taxonomic notes on the genus Rosenbergia Ritsema, 1881 with description of a new species and subspecies (Coleoptera: Cerambycidae: Lamiinae)
Abstract: The R. dianneae species group of the genus Rosenbergia is described and enlarged with the additional descriptions of R. cheesmanae sp. nov. and R. valentinae eki ssp. nov. Adult genitalia are depicted. The R. weiskei species group is analysed and Rosenbergia valentinae Rigout, 2004 stat. nov. is raised to species level and no longer considered a subspecies of R. dianneae Allard, 1990. The rediscovery of the holotype of Rosenbergia humeralis Gilmour, 1966 allows for the description of the male of this species. After extensive research, the holotype of R. dianneae is considered lost and a neotype has been designated.
