A Revised Key to Leptocaris (Copepoda: Harpacticoida), Including a New Species From a Shallow Estuarine Lake in Louisiana, USA


During ecological research of benthic and fouling assemblages in a shallow estuarine lake in central Louisiana receiving thermal effluent, a new species of harpacticoid copepod was discovered. Approximately 700 specimens of Leptocaris kunzi n. sp. were collected on artificial substrate plates from August, 1977 - January, 1978. This new species is herein described and illustrated. Leptocaris kunzi n. sp. differs from other members of the nominal genus in the setation of the P2 - P4 endopods and by having a female P5 not fused into a single plate. The most closely related species to L. kunzi n. sp. appear to be L. elishevae (Por) and L. canariensis Lang. A revised key to the genus is presented.
