Diagnosis.
Test is free, elongate, triangular in cross-section, and curved at the basal part. Early portion is planispirally coiled and the later portion is uniserial. Sutures are slightly depressed and gently curved in lateral view. Test is composed of nine chambers, and chamber size gradually increases as added. Aperture is terminal, slightly produced, and radiate. Wall is calcareous, hyaline, and the surface is smooth. Test length is about 950 μm.
Remarks.
This species is originally classified as belonging to subgenus
Cristellaria
(
Saracenaria
)
. According to Hayward
et al.
(2019),
Saracenaria
was upgraded to genus level by
Zheng and Fu (2008)
listing
Saracenaria hannoverana
as a valid species. This species has been reported from Chinese regions in the East
China
Sea (
Hayward
et al.
, 2018c
) and this is the first report from
Korea
. According to NIBR (2019), four species belonging to
Saracenaria
have been reported in
Korea
:
S. altifrons
,
S. angularis
,
S. italica
, and
S. latifrons
.
Saracenaria hannoverana
differs from
S. altifrons
in the shorter and less inflated apertural face.
Saracenaria hannoverana
differs from
S. angularis
by having a smooth periphery without a keel. The present species also differs from
S. italica
by having a narrower apertural face and constant chamber width. Additionally,
S. hannoverana
differs from
S. latifrons
by having a shorter apertural face and a gently acute dorsal margin without keel.
