Material examined
BRAZIL
: Estre outcrop, Rosário do Catete Municipality,
Sergipe State
(samples MP-1423 and MP- 1424), approximate coordinates
10°41' S
,
37°02' W
.
Measurements
Hypotype (CP-715): left valve: length =
0.43 mm
, height =
0.25 mm
.
Hypotype (CP-766): right valve: length =
0.38 mm
, height =
0.23 mm
.
Remarks
The generic diagnosis follows
Gründel (1964)
and the suprageneric diagnosis follows
Gründel (1966)
. The figured specimens are apparently less ornamented than other species of
Quasihermanites
Gründel, 1964
, especially with regard to its characteristic lateral ribs (
Kuznetsova 1961
;
Gründel 1964
;
Donze 1965
;
Pokorný 1973
;
Colin 1974
;
Babinot
et al.
1985a
;
Babinot & Colin 2011
). The probable reason for that would be diagenesis, similar to that observed in the
type
material of
Quasihermanites spiralus
Schudack & Schudack, 2000
(
Schudack & Schudack 2000
). Therefore, the present authors classify it questionably as
Quasihermanites
.
