notes. This species is closely allied to confusa
and both have been erroneously placed as synonyms of Chorsia
as discussed on p. 412. Typical stipata (slide 18527) has a more rounded interior margin to
the basal half of the valve sacculus rather than having a right-angle distally
(Inoue et al., 1982: plate 374: 6). The curved, digitate process
dorsal to this is longer in stipata. This feature is shared by the Bornean
specimen; however, the valve is narrower, the apex extending further beyond the
more distal triangular process on the interior saccular margin, and also the
saccus is rounded rather than acute. This Bornean specimen may represent a third
species, but the differences noted are slight enough to require further material
from both localities to ensure these are consistent.
