Abstract

A new species of the harpacticoid copepod genusEsolais described from specimens collected in Rodadero Beach, on Gaira Bay, on the Caribbean coast of Colombia. The species,E. wellsisp. nov., is described, illustrated, and com­pared with its congeners.Esola wellsisp. nov.differs from its known congeners in details of the armature of legs 1–4. It most closely resemblesE. bulbifera(Norman, 1911) in the armature formula of P1–P5 but differs from the latter in several respects, including the female antennule segmentation (7-segmented inE. bulbiferabut distinctly 6-segmented inE. wellsisp. nov.) and in the shape and size of the male P3ENP2 apophysis, among other characters. This is the second species of the genus known from the Caribbean and the second record ofEsolain the Northwestern Tropical Atlantic. The genus now contains eight species. A key to the known species of the genus is also included.
