Carvalho, Francisca C. & Pisera, Andrzej, 2019, Revision of the genus Exsuperantia Özdikmen, 2009 (Tetractinellida: Phymaraphiniidae) with description of a new species from the Atlantic Ocean, Zootaxa 4613 (1), pp. 135-151 : 137-138

Genus Exsuperantia Özdikmen, 2009

Synonymy. Rimella Schmidt, 1879: 21 (preoccupied); Racodiscula sensu Topsent, 1892 ( Topsent 1904, 1928) (wrong generic assignment).

Type species. Rimella clava Schmidt, 1879: 21 .

Diagnosis. Phymaraphiniidae with a clavate shape, and phyllotriaenes as ectosomal spicules (Pisera & Lévi 2002b).

Description. Clavate to columnar sponges; ectosomal spicules are smooth phyllotriaenes; choanosomal macroscleres are subtylostyles to tylotes, and desmas are triders with smooth and/or tuberculated tubercles; microscleres are acanthomicroxeas, acanthorhabds and amphiasters (emended from Pisera & Lévi 2002b).

Remarks. Schmidt (1879) described a new genus from the Gulf of Mexico with the type species Rimella clava . However, Rimella was already preoccupied by a gastropod defined by Agassiz (1840), turning Rimella Schmidt into a junior synonym of Rimella Agassiz ( Özdikmen 2009) . More recently, the original Schmidt material (1879) was redescribed and reillustrated by Pisera & Lévi (2002b).
