Diagnosis Test involute to evolute, centrally thickened, megalospheric proloculus followed by up to sixteen operculinoid and unfolded septa, larger and relatively rare microspheric test with about thirty unfolded septa, then with chamberlets formed by complete secondary septa produced by folds of the septal flap, no communication between adjacent chamberlets of the same chamber, marginal cord consists of an anastomosing bundle of canals in the peripheral band that are continuous with those in the spiral septum of earlier whorls, intraseptal canals formed from part of former marginal canals as new chamber is added, and connect the marginal canals of successive whorls, secondary sutural canals in the septula forming the chamberlets connect successive sutural canals, and those in peripheral position may lead into the marginal canals, apertures of proloculus and early undivided chambers form the primary stolons or apertural or foraminal tubes, later chambers and chamberlets of a single chamber connected by radial stolons or tubes and may also have annular stolons or tangential tubes, so-called because of their position, Y-shaped supplementary stolons occur at the distal tip of the secondary septula in the median plane, smaller connections occur between the chamber lumen and peripheral canals of the final whorl and spiralling canals of the underlying whorl and may also lead to the intraseptal canals, canal system opens through small branches or trabeculae into the relatively large pores or openings of the marginal, septal and secondary septal canals and to the exterior; wall calcareous, finely perforate, chambers and stolons with organic lining but none present in the canal system, up to six interseptal pillars present on the lateral chamberlet walls; openings of the canal system along the periphery may serve for ingestion of nutrients, waste excretion, and exit of the protoplasm from the test at the time of sexual reproduction; live individuals have endosymbiotic diatoms whose photosynthesis provides nutrition for the host; asexual reproduction by multiple fission of protoplasm that earlier had streamed outside the test, producing 100 to over 1,000 young that obtain symbionts from the parent protoplasm, rarely some residual protoplasm remains in the parent cell, continues to grow, and later reproduces a second time; at gamogony thousands of 120 µm ovoid biflagellate gametes are produced. U. Eocene to Holocene; cosmopolitan, tropical to temperate Atlantic, Pacific, and Indian Oceans. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
