Four new species of unilocular calcareous foraminifera are described from Holocene sediments of the southwest Pacific Ocean. Vasicostella cranimorpha sp. nov. is distinguished by a lenticular tubule that pierces each margin of the peripheral carina. Globofissurella pattersoni sp. nov. is characterized by a large, produced circular apertural area ornamented in part by costae continuing from the chamber surface. Palliolatella peponisema sp. nov. bears a strong resemblance to a pumpkin seed, and has quite variable development of its central keel. Parafissurina thryptica sp. nov. is distinctly teardrop-shaped, with its greatest diameter near the base, and a mildly acute apertural end.
