Diagnosis Test lenticular, prominent surface reticulations obscure the sutures, but sectioned or dissected specimens show the chambers to be biserially arranged and planispirally enrolled as in Islandiella, alternate chambers extending to the umbilicus on opposite sides, periphery acutely angled; wall calcareous, primary wall indistinctly optically radial, as the calcite crystals are dendritic in form and occur in bundles, inner and outer surface of the wall covered by a microgranular veneer, the variation in wall structure resulting in thick walls appearing optically granular, finely perforate, surface covered with secondarily formed honeycomb network of narrow elevated ridges forming polygonal open areas, the polygonal mesh becoming more prominent with lamellar growth, area immediately adjacent to the aperture smooth to radially grooved but without the polygonal mesh; aperture an elongate, slightly curved slit paralleling the chamber margin, anterior margin with a narrow lip, toothplate at the posterior margin, its slightly protruded external portion forming a narrow cristate tooth that fuses with the lip at the upper end of the aperture but leaves a gap between these at the lower end, internally a small primary tongue arises from the septal wall nearest the anterior end of the preceding apertural foramen as in Islandiella. M. Miocene to Holocene; Pacific Ocean; Indian Ocean. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
