Type species (by present designation): Fabricia oregonica Banse, 1956.
Definition. There is no phylogenetic hypothesis to which Bansella refers (see Fitzhugh 2008 b). To satisfy ICZN requirements, the following list of characters form a unique combination among individuals to which this name applies: (1) prominent, anterior peristomial ring lobe, (2) triangular dorsal lips, (3) pigmented spermathecae in branchial lobes, (4) inferior thoracic notochaetae narrowly hooded in all chaetigers (see also Remarks section below, under Bansella oregonica (Banse), comb. nov. ).
Etymology. The genus is named in honor of Dr. Karl Banse, who made numerous and significant contributions to the systematics of Fabriciinae sabellids.
Remarks. Bansella is a monotypic genus, with B. oregonica, comb. nov., as the only species. The purely utilitarian justification for erecting yet another monotypic genus (see also Monroika Hartman, 1951, Pseudofabricia Cantone, 1972, Parafabricia Fitzhugh, 1992, Brifacia Fitzhugh, 1998, and Raficiba Fitzhugh, 2001) in the subfamily will be discussed below (Justification for the recognition of Bansella ).
