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.
