Abstract
A new species of Andiorrhinus Cognetti, Andiorrhinus meansi sp. n. from the Wokomung Massif, an isolated sandstone tepui in the Guyanan interior, in cloud forest with a thick organic soil, is described and named for its collector, D. B. Means. This giant earthworm with last hearts in the 11 th segment is placed in the subgenus A. (Turedrilus) Righi, but is not otherwise morphologically similar to other members of the subgenus. It differs in the numbers and locations of spermathecae, the form of the calciferous glands, and body size. In consideration of the morphology of the newly described species and after reviewing the majority of Andiorrhinus species, it is proposed to abandon the subgenera within Andiorrhinus pending more detailed study and a revision of the genus.References
