Frýda, Jiří, Ferrová, Lenka & Frýdová, Barbora, 2013, Review of palaeozygopleurid gastropods (Palaeozygopleuridae, Gastropoda) from Devonian strata of the Perunica microplate (Bohemia), with a re-evaluation of their stratigraphic distribution, notes on their ontogeny, and descriptions of new taxa, Zootaxa 3669 (4), pp. 469-489 : 474

Cimrmaniela gen. nov.

Type species. Cimrmaniela sveraki sp. nov.

Diagnosis: Palaeozygopleurid with small, very slender, high-spired, multiwhorled shell having straight sides, narrow apical angle; whorl profile very convex; whorls ornamented by regularly spaced, opisthocyrt or orthocline costae; large protruding protoconch.

Comparison: Species of Cimrmaniela differ from all other palaeozygopleurid species by their small and very slender, high-spired and multiwhorled shells. Only species of Bojozyga have such slender shells (i.e., having a very narrow pleural angle). Whorls in both known species of Bojozyga are only gently convex and they are distinctly appressed, forming a typical sutural band (see Horný 1955: pl. III, figs 5, 6), in contrast to the shells of Cimrmaniela . Except for the latter characteristics, the species of Cimrmaniela differ from those of Bojozyga in having much smaller shells. Species of Cimrmaniela differ from Pragozyga Frýda, 1999 , by their very slender, high-spired shells (compare Fig. 2 with fig.1a in Frýda et al. 2008).

Etymology: Cimrmaniela , in honour of Jára Cimrman, who was one of the greatest Czech universal scientists and artists of the 19th and early 20th century.

Species included: Cimrmaniela sveraki sp. nov. and Cimrmaniela smoljaki sp. nov.
