Diaphus sp. 1

(Figure 41)

Material: 1 specimen in total. Roxas (1) RGM 962143.

A well-preserved 2.7 mm sized Diaphus specimen is characterized by an ovaloid shape (OL:OH= 1.30); a strong rostrum protruding clearly beyond the feeble antirostrum; a rounded dorsal rim with a flattened predorsal part, a marked postdorsal angle, followed by a clear postdorsal depression; and a regularly rounded ventral rim with 11 distinct denticles. The specimen probably belongs to a Diaphus species in the D. splendidus Bauer, 1904 or D. signatus Gilbert, 1908 otolith groups.
