Praetaberina apula
Consorti et al., 2015
Reference Illustration & Description
Consorti et al. (2015)
,
Fig. 8
, p. 382-384.
This is a relatively new species defined by
Consorti et al. (2015)
based on new samples from the Bari Formation of
Italy
and re-examination of specimens previously attributed to
Taberina bingistani
by
Fleury (1980)
in
Greece
and by Borghi & Pignatti (2006) in
Italy
.
Specimens of
P. bingistani
are larger overall and have up to three and a half initially coiled whorls compared with a maximum of only two initially coiled whorls in
P. apula
. The septula are fewer, but they extend further inwards within the chamber than
P. bingistani
, thus reducing the central chamber space available for the apertures and pillars. See the Species Key Chart (Appendix) for diagnostic and other characteristics.

Reported only from
Greece
(
Fleury, 1980
) and
Italy
(Borghi & Pignatti, 2006) as
P. bingistani
but now referable to
P. apula
(following
Consorti et al. 2015
). The two species of
Praetaberina
discussed here would therefore appear to have mutually exclusive distribution patterns.
Mohajer et al. (2022b)
reports the occurrence of
P. apula
from the Izeh Zone of the Iranian Zagros, but only as originally reported by
Khosrow Tehrani & Fonooni (1994)
i.e., before the species was first described. It is not known by what means
Mohajer et al. (2022b)
concluded that this occurrence is, in fact,
P. apula
. This record is not included on the distribution map.
