A new species of the genus Pseudomonocelis (P. caribbea sp. n.) is described. It is distinguished from congenerics by shape and size of the copulatory organ and relative positions of mouth and genital openings. It is the first species of the genus found in America. Sampling in east Africa (Zanzibar island) revealed two species, attributed to P. pardii and, tentatively, to P. cavernicola, both originally described from Somaliland. Morphological differences between Tanzanian and Somali specimens are reported. The Mediterranean P. ophiocephala, based on extensive morphological and karyological survey of 13 populations, is interpreted as constituting at least two sibling species, distinguishable solely on the basis of karyotype. Results support the notion that the present perception of the contribution of interstitial Rhabditophora to marine biodiversity may be unrepresentative.
