Summary
The formerly little-known burrowing sea anemone Isoedwardsia lucifuga (Fischer) has been rediscovered in several localities. A study of this species has shown that it is conspecific with Scolanthus callimorphus Gosse, which has until now been confused with a common species of Edwardsia. This has resulted in the following nomenclatural changes:
(1) Scolanthus callimorphus Gosse, 1853 is recognized as a valid species with a number of junior synonyms, including I. lucifuga. | |||||
(2) The genera Isoedwardsia Carlgren, 1921 and Alfredus Schmidt, 1979 are shown to be junior synonyms of Scolanthus Gosse, 1853. | |||||
(3) Edwardsia claparedii (Panceri, 1869) is now regarded as the valid name of the anemone hitherto known as E. callimorpha. |
A full synonymy and brief description of S. callimorphus are provided, together with notes on its burrowing behaviour.
