Abstract

Two specimens of Campylonotus arntzianus sp. nov. were caught in the Antarctic Scotia Sea off Saunders Island (57°40.31'S, 26°27.81'W) using an Agassiz trawl at one station (depth: 475–589 m). The new species described here is the fifth representative of the monogeneric family Campylonotidae, and the first of the family south of the Antarctic Convergence. Campylonotus arntzianus sp. nov. is a shrimp of about 5 cm in total length. Due to similarities in adult morphology, C. arntzianus sp. nov. seems to be closely related to C. capensis, a deep-sea species from the Southern Atlantic Ocean. A simple key for the species identification of the Campylonotidae is provided.

In addition to his extensive research on Antarctic decapods and invertebrate communities in general, he encouraged my own interest in this subject and greatly supported my scientific work. I am indebted to Dr. Martin Boche and his crew of the German PFS Polarstern for help and assistance at sea, and to Dr. Gustavo Lovrich, M. Carolina Romero, Federico Tapella and Fabian Vanella for the excellent working atmosphere and fruitful research during this cruise. Dr. Martin Rauschert kindly provided the holotype photograph published in this work. I am grateful to Dr. Pablo J. López-Gonzalez and two anonymous reviewers for their helpful comments on the manuscript. I would like to thank Ruth Alheit for her revision of the English.
