Postembryonic development of Drescheriella glacialis Dahms & Dieckmann (Copepoda, Harpacticoida) reared in the laboratory

  • Hans-Uwe Dahms
Article

Summary

All 6 naupliar and 5 copepodite stages of Drescheriella glacialis, a tisbid from Antarctic fast ice, are described. A key for the identification of the naupliar stages is given. Sexual dimorphism makes its first appearance in the copepodid IV. The setae configuration of the exopod of the second antenna in copepodid I is considered to be an ancestral state, and subsequent ontogenetic reductions are proposed to be apomorphic processes.
