7–8 in
pl. 1)
Material examined
.
— 2 sagittae (
NMMBOL
0799, 1007).
Description
.
— Oval to oblong shape, slightly convex medial face and slightly concave lateral face. Dorsal margin slightly irregular and ventral margin rounded and minutely crenate in the middle. Crista superior well developed except for above the anterior cauda, where slightly ridgelike. Dorsal trough visible to crista superior. Crista inferior moderately developed. Cauda straight anteriorly, flexing sharply at two-thirds of the length. Ostium broad, the posteroventral corner wide, pointing posteriorly to form a lobe. Excisural notch absent.
Dimensions
.
— OL,
7.38–7.72 mm
; OH,
5.02–5.52 mm
; OT,
1.56–1.67 mm
; OsL,
2.52–3.09 mm
; OsH,
1.76–1.88 mm
.
Diagnosis
.
— The broad ostium (caused in part by a deep trough near the dorsal margin of the ostium), with a well-developed posteroventral corner (creating a lobe) is diagnostic. The relative thinness and slender outline of the sagittae are also diagnostic.
