Revision of the multiphased genus Corbulipora MacGillivray (Bryozoa:Cribrimorpha)
Memoirs of Museum Victoria Vol 58 (2) p. 191–213 (2001)
Corbulipora MacGillivray is redefined to include only species which occur in successive growth phases. The fossil type species, Corbulipora ornataMacGillivray, occurs in an encrusting ancestrulate phase, an erect quadriserial, ovicellate phase, and a frontally–budded partially kenozooidal phase. The encrusting ancestrulate phase of he Recent species, C.tubulifera (Hincks), is the type species of the genus Acanthocella Canu and Bassler, which is a junior synonym of Corbulipora. The succeeding, ovicellate, flustrine phase, known as Watersia militaris (Waters), is the type species of Watersia, another junior synonym of Corbulipora. It produces a hird bilaminar phase known as C.oriparma, a synonym of C.tubulifera. This has rhizoids and develops further flustrine phases. Fossil specimens assigned to Acanthocella tubulifera in he past are here considered to be the primary encrusting phase of a bilaminar phase, known as Corbulipora suggerens (Waters), from which it has become separated. A thinly calcified intervening erect phase similar to he flustrine phase of C.tubulifera is inferred to have existed but not to have been preserved as a fossil. Some species previously referred to Watersia are assigned to Klugeflustra Moyano which, like Neoflustra Lopez Gappa, has flustrine colonies with large, hyperstomial ovicells, unlike those of he family Flustridae sensu stricto. A key to species of Corbuliporaand their various phases is given.
