Eucytherura aff. antipodum Neale, 1975

Fig. 3 Q-R

" Eucytherura sp. 8" Ayress, 1988 *: 624; pI. 22, figs 7 -9.

Dimensions. Adult right valve, MA/IP/426, length 0.31 mm, height 0.13 mm.

Diagnosis. Subrectangular and weakly inflated. Surface reticulate, fossae well rounded, muri thickened over posteroventral tubercle which overhangs ventral margin. Strong crescentic rib extends close to margin posterodorsally and a short oblique rib is present subcentrally. Ventral surface microreticulate.

Comparisons. The single specimen found in this study has strong affinities with E. antipodum Neale recorded in the Late Cretaceous Gingin Chalk of western Australia and clearly is closely related to it. The specimen differs from that species only in having weaker anterodorsal and subcentral tubercles and lacking fossal infillings. It is also very similar to E. pseudoantipodum Coles & Whatley , differing from that species in its more elongate lateral outline, its thickened muri on the posteroventral tubercle and lack of fossal spines.

Distribution. So far this species has been recorded only in the Pleistocene of DSDP Site 254, at the southern limit of the Ninetyeast Ridge, Indian Ocean.
