APÈNDIX
Diagnoses of the new species
(English translation)
Moitessieria mugae sp. nov.—
Average-sized species of Moitessieria,
comparable to M. simoniana (average
length 1.9 mm, average width 0.6 mm);
turriculate and elongated shell, usually with
6-6½ whorls, subcylindrical and slender
(average length/width index of 3.1);
planoconvex whorls, with superficial and
slightly-inclined sutures (18º on average);
external aperture lip slightly prominent, with
the last whorl not being very inflated;
slightly marked sinule; upper edge of the
peristome very adhered to the parietal
zone; peristome not expanded at all and
slightly reflected at columellar level; closed
(obliterated) umbilicus; ornamentation of
the teleoconch formed by a slightly-marked
reticule of quadrangular depressions, with a
low striation density; protoconch without
noticeable ornamentation.
Moitessieria collellensis sp. nov.—
Large-sized species of Moitessieria
(average length 2.2 mm, average width 0.9
mm); turriculate and elongated shell,
usually with 6¾-7¼ whorls,
conicocylindrical and moderately to very
robust (average length/width index of 2.4);
convex whorls, with deep and very-slightlyinclined
sutures (13º on average); external
aperture lip prominent, with the last whorl
not being very inflated; very marked sinule;
upper edge of the peristome slightly
separated or slightly adhered to the parietal
zone; peristome very expanded and
generally very reflected at columellar level;
open and usually very wide umbilicus;
ornamentation of the teleoconch formed by
a well-marked reticule of quadrangular
depressions, more marked in spiral
direction, with a low striation density;
ornamentation of the protoconch consisting
on spirally arranged papillae and
discontinuos crests.
