Bobiesipora fasciculata – Zágoršek 2003: 119, pl. 5, fig. 3 (cum syn.).

MATERIAL EXAMINED. — Four syntypes of Alveolaria buski registered as 1862/0022/0055. No lectotype selected.

DIAGNOSIS. — Colony with a large circular encrusting basal part. Branches with zooecial tubes irregularly arranged around base. Branches often bifurcate, perforated by many kenozooecia and apertures in fascicles. Fascicles corresponding with a keel on dorsal surface of colony. Gonozooecium not observed.

REMARKS

In the absence of a gonozooecium in the Stoliczka specimens, the attribution to Bobiesipora remains uncertain.However, all other features (arrangement of apertures, branches and kenozooecia) show high similarities with Bobiesipora fasciculata .

Figures

FIG. 1. — A, Exidmonea hoernesi (Stoliczka, 1862), general view of holotype showing diagnostic features: one aperture, close to the dorsal side of the colony, which is always arranged outside the fascicle; B, Exidmonea giebeli (Stoliczka, 1862), general view of holotype; C, D, holotype of Filisparsa tenella identified as Filisparsa? sp. due to the poor preservation and lack of the gonozooecium; E, one of the syntypes of Pustulopora (Clausa) retifera identified as Mecynoecia cf. pulchella (Reuss, 1847) owing to the lack of a gonozooecium; F, holotype of Pustulopora attenuate identified as Mecynoecia cf. proboscidea (Milne-Edwards, 1838) owing to the lack of a gonozooecium; G, H, syntype of Alveolaria Buski identified as?Bobiesipora fasciculata (Reuss, 1848); J, holotype of Heteropora similis Stoliczka, 1862, identified as nomen dubium due to the very poor preservation and the absence of a gonozooecium or any other characteristic features; K, L, holotype of Pavotubigera anhaltina identified as “Disporella anhaltina (Stoliczka, 1862)” nomen dubium owing to poor preservation and the absence of a gonozooecium.
