SECOND LIST OF PYCNOGONIDA OF THE UNIVERSITY OF CAPE TOWN ECOLOGICAL SURVEY

Abstract

Records of 21 species from South African waters. Three of these (Nymphon lobatum, N. pleodon and Nymphopsis varipes) are new to science, the remaining species being already known from the region, although several of them are recorded for the second or third time only. The new Nymphopsis is morphologically remarkable because the first pair of legs, which are uniunguiculate and possess a transformed propodus, differ in structure from the 2nd to 4th legs, which have auxiliary claws and normal propodal segments. A comparable dimorphism is rare among the Pycnogonida.
