Abstract

Two specimens of Dolichiscus spinosetosus were collected by means of an Agassiz trawl and a small dredge in the Weddell Sea, Antarctica. This species is characterized by a large number of strong spines on the dorsal side, some of these possessing tubercular tips. The dorsum is characterized by many smaller and shorter blunt spines and numerous long simple setae all over the body (on spines, pereonites and pleotelson). Dolichiscus acanthaspidus Schultz, 1981 is the taxon most closely related to this new species, but the new species has more setae and tubercular spines on all parts of the body and two caudolateral spines instead of one behind the supraocular ones.
