Genus Bathydorus Schulze, 1886

Type species: Bathydorus fimbriatus Schulze, 1886 (by subsequent designation; Koltun, 1967).

Genus diagnosis. Rossellinae with tubular, saccular, or plate-like gross morphology. Basiphytous or lophophytous, thin-walled. Dermalia are combinations of spicules from hexactins to diactins. Regular pentactins make up a hypodermal layer. Choanosomal skeleton composed of diactins, sometimes with hexactins. Atrialia are hexactins or stauractins. Microscleres are combinations of oxyoidal hexasters, hemihexasters, and hexactins; lacking pappocomes (From Tabachnick 2002b: 1463, emended).

Remarks. The diagnosis of the genus is emended to include the plate-like gross morphology, lophophytous method of attachment, and atrial stauractins that occur in the new species.
