Test elongate, flabelliform, globular proloculus followed by a few biserial chambers, then becoming uniserial, with broad, arched, and flattened chambers that have a thickened, elevated, and commonly nodose lower margin, overhanging laterally so that test margins appear serrated, sutures arched across the flat sides of the test; wall calcareous, optically radial, distinctly perforate, surface smooth except for the nodose lower chamber margins and occasional nodes elsewhere on the chambers; aperture not known, probably consisting only of pores as in Pavonina, intercameral foramina large, extending the length of the septal face and separated only by narrow bridges from one side of the test to that opposite. Pleistocene to Holocene; Pacific: Ryukyu Islands; Timor Sea. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification)
