Family Rossellidae Schulze, 1885

Abstract

Rossellidae Schulze (Hexactinellida, Lyssacinosida) is revised to contain 22 genera in two subfamilies: Lanuginellinae with seven genera (Lanuginella, Calycosoma, Doconesthes, Lanugonychia, Lophocalyx, Mellonympha and Sympagella) and Rossellinae with 15 genera and 12 subgenera (Rossella, Acanthascus: A. (Acanthascus), A. (Rhabdocalyptus), A. (Staurocalyptus), Anoxycalyx: A. (Anoxycalyx), A. (Scolymastra), Aphorme, Asconema, Aulosaccus, Bathydorus, Caulophacella, Caulophacus: C. (Caulophacus), C. (Caulodiscus), Crateromorpha: C. (Crateromorpha), C. (Aulochone),C. (Craterochone) subgen. nov., C. (Neopsacas)subgen. nov., C. (Caledochone), Hyalascus, Schaudinnia, Scyphidium, Trichasterina, Vazella and Vitrollula. Representatives of the former family Caulophacidae are transferred here to Rossellidae. The subfamily Acanthascinae is abolished and becomes a junior synonym of Rossellinae. Thus, Rossellinae comprises Rhabdocalyptus and Staurocalyptus which are regarded as subgenera of Acanthascus; Scolymastra becomes a subgenus of Anoxycalyx; Caulodiscus a subgenus of Caulophacus; and Aulochone a subgenus of Crateromorpha. Two new subgenera of Crateromorpha are described: Craterochone subgen. nov. and Neopsacas subgen. nov.
