Boschitestella cf. eloiseae Moolenbeek, 1994
Maximum size: 0.9 mm shell
diameter.
Identification:
The
shell
of
this
species has a single sharp keel on its periphery. The
keel is crossed by relatively fine, angled axial ribs. Some
shells from deeper water at Midway Atoll have fewer but more prominent
axial ribs that form short spines on
the keel.
Natural history:
Shells
of
Boschitestella cf.
eloiseae are
moderately rare in
beach drift and subtidal sand samples.
Distribution:
Maui, French Frigate Shoals and Midway: Boschitestella
eloiseae
is known from Japan.
Taxonomic notes:
Shells
of
this
species
are very similar to those of Boschitestella
eloiseae as
illustrated in Okutani, 2000. It's possible that the "spiny" Midway
shells may be a separate species but the spines become less prominent
in larger shells (and in shallower water) arguing for lumping.
