Additions to the inventory of eastern tropical Atlantic ascidians: arrival of cosmopolitan species

Author(s): Monniot C, Monniot F

Abstract

An inventory of eastern tropical Atlantic ascidians is based on collections made using SCUBA and dredges during the 1990 cruise of the R/V Sea Diver by Harbor Branch Oceanographic Institution. This account incorporates other samples previously taken in the same area. Two new species are described and the taxonomic status of 43 other species is reviewed; several of these species are extensively redescribed. The arrival of cosmopolitan species, absent from previous lists, is attributed to ship traffic.
