Pomadasys maculatus ( Bloch, 1793)

( Fig. 3c ; no. 5–6 in pl. 1)

Material examined. — 22 sagittae ( NMMBOL 0717–0720, 3816–3824, 3832–3834, 3923–3928).

Description. — Suboval in shape with moderately convex medial and moderately concave lateral faces. Thick centrally. Dorsal margin sinuate, ventral margin crenate. Crista superior and crista inferior moderately- to well-developed along sulcus. Dorsal trough visible to crista superior. Posteroventral corner of ostium round. Caudal flexion appears mid-length, turning downward nearly 90 degrees. Excisural notch deep and acute, pointing forward.

Dimensions. — OL, 5.28–8.57 mm; OH, 4.20–6.21 mm; OT, 1.12–2.27 mm; OsL, 2.60–4.51 mm; OsH, 1.26–2.09 mm.

Diagnosis. — The deep notch is diagnostic of P. maculatus . This species also shows a larger otolith height than P. argenteus and P. kaakan in a similar otolith length.
