DIAGNOSIS. — Colony erect, multiserial. Autozooecia may be rhomboidal in central part of colony, more elongate on colony margin. Frontal shield granular, perforated by marginal areolar-septular pores. Orifice with transversely D-shaped anter and narrow sinus. Adventitious avicularia small, paired, one on either side suborally. Maternal zooecia up to more than twice as wide distally as autozooecia, with smooth ooecial margin much wider than long, showing beneath distal secondary calcification. Secondary zooecial calcification often accompanied by tubercles situated usually in margins and / or on frontal shield including loci of suboral avicularia.

REMARKS Ŋis species differs from A. ornatissima in having very large maternal zooecia, longer autozooecia with granular frontal shields, and suboral (not lateral-oral) avicularia. It is similar also to Adeonella minor (Reuss, 1869) which, however, never has such large brooding zooids and the apertural sinus is less prominent.

MATERIAL EXAMINED. — Two syntypes registered as 1859 / 0026 / 0137. Ŋe chosen lectotype (designated here) corresponds with Stoliczka’s illustration (1862: pl. 2, fig. 6) and is depicted as Figure 3 E herein.

This dataset contains the digitized treatments in Plazi based on the original journal article Zágoršek, Kamil, Gordon, Dennis P. (2014): Revision of the Oligocene bryozoan taxa described by Stoliczka (1862), with the description of a new genus of Bryocryptellidae. Geodiversitas 36 (4): 541-564, DOI: 10.5252/g2014n4a3, URL: http://dx.doi.org/10.5252/g2014n4a3

ABSTRACT

A collection of bryozoans from the Oligocene of Latdorf, Germany, first described by Ferdinand Stoliczka in 1862 and not examined since, has been reexamined. Stoliczka had recognized 47 species, 24 of them new. Of these latter, 14 names remain valid; the remainder are synonyms of previously described taxa or, owing to the originally inadequate state of the fossil material examined, taxonomically indeterminable. Ŋe genera Orbitulipora Stoliczka, 1862 and Stichoporina Stoliczka, 1862, both introduced by Stoliczka in 1862 along with their type species, are still valid. Two of his species, one of which had not been examined since its first description, comprise a new bryocryptellid genus, Stoliczkella n. gen., which superficially resembles the celleporid genus Galeopsis Jullien & Calvet, 1903. Diagnoses or descriptions are provided herein for all of the taxa in the collection and lectotypes selected. Ŋe results of this revision will be applied to a forthcoming analysis of a recent extended excavation of the Latdorf section by the University of Leipzig, in which bryozoans are among the most abundant fossil groups.
