Abstract

Calomicrolaimus rugatus gen., n., sp. n. (Microlaiminae, Desmodoridae) from a sandy beach of the Atlantic coast of Colombia is described. The new genus possesses three outstanding features: The male amphids are smaller than the female ones and have a rodlike corpus gelatum; the males have conspicuous cervical setae, and they have special ventral thickenings of the body annules in the preanal region.
