摘要:

Until 1986, the genusCeriodaphniawas thought to be commonly represented in New Zealand by only one species,C. dubiaRichard, 1894. Recent work in the Waikato area has revealed a second very common species, C. cf.pulchellaSars, 1862. The two species differ in the structure of the postabdomen, postabdominal claw, antennules, ocellus, and ephippium. These morphological details, together with guidelines for the rapid identification of the two species from field samples, are discussed.
