Scientific Name: Lavigeria paucicostata (Bourguignat, 1888)
Taxonomic Notes: The taxonomy of Lavigeria is currently under large-scale revision. Existing taxonomy (Brown 1994) recognizes only two species (L. grandis and L. nassa), however revision (Michel and Todd in prep) will include approximately 43 species. Included here are a few of the name-bearing taxa whose names (from older literature, but not always consistently applied) have been used in relatively recent literature and are included in West et al. (2003). West et al. 2003 includes 20 Lavigeria species, Michel et al. 2004 includes 28 species. Extensive ecological information is available on a number of Lavigeria species, especially in the Kigoma, Tanzania region. (E. Michel, pers. comm.) Lavigera paucicostata is not well defined and past uses of the name are likely to be in error according to current taxonomy.
