The species was first described under the name
Stereoclavella australis in 1898 by
William Abbott Herdman, although that taxon was considered a
nomen nudum. A formal taxonomic description of the species was written by Herdman the next year, alongside a tentatively named
Stereoclavella sp. ?
australis from
Broughton Island. The two descriptions differed in the structure of their dorsal languets, united in the latter by a longitudinal band but directly joined to the horizontal membranes in
S. australis. The original genus
Stereoclavella was later synonymized with
Clavelina, giving the tunicate its currently accepted binomial name. == Description ==
