Genus Breitfussia n. gen.

TYPE SPECIES. — Ebnerella schulzei Breitfuss, 1896 .

DIAGNOSIS. — Jenkinidae with a simple tubular body and syconoid organization. The choanoskeleton is reduced to the unpaired actines of the subatrial triactines, and occasionally contains the proximal part of radial diactines.

DESCRIPTION

In the system proposed by Lendenfeld (1891), and followed by Breitfuss (1896), the genus Ebnerella of the subfamily Amphoriscinae was characterized by an inarticulate skeleton, containing diactines, triactines and/or tetractines. The species included by Lendenfeld (1891) in this genus belongs now to the genus Amphoriscus and Ebnerella is thus a junior synonym of Amphoriscus . Among the species described by Breitfuss (1896) in Ebnerella , E. kuekenthali belongs to the family Heteropiidae (Sycettusa) , but a new name is needed for E. schulzei . In addition, species with an inarticulate choanoskeleton, described under the genus Grantia or Dermatreton , should be included in the new genus Breitfussia as now defined, such as Breitfussia (Grantia) vitiosa (BrØndsted, 1931) and Breitfussia (Dermatreton) chartacea (Jenkin, 1908) . Breitfussia is known only from cold Arctic or Antarctic waters.
