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.
