Thecidellina minuta
Cooper, 1981
(
Fig. 13
)
Numerous specimens of
T. minuta
were found in only one sample, from Crypthelia seamount (
Tables 1
, 2) at
267 m
(
Fig. 14
). This thecidellinide is characterized by its very small size and the presence of pseudodeltidium. The brachial cavities are covered by reticulated canopying spicules (
Fig. 13
D-I). Because of its very small size the species might easily be taken for a juvenile of
Thecidellina maxilla
; however, the presence of a pseudodeltidium (observed in all ontogenic stages, Jana Hoffmann pers. comm.) clearly distinguishes
T. minuta
from
T. maxilla
. This is the first record of
T. minuta
from the Pacific; so far it is known only from the western part of the Indian Ocean (
Cooper 1981
;
Zezina 1994
;
Lee & Robinson 2003
).
