Description Test elongated, subconical, with trochospiral coiled initial part later becoming rectilinear with uniserial chambers. The apertural face is almost flat to slightly convex. Early stage with small subspherical embryo (diameter ~0.025-0.04 mm), followed by a trochospire formed by low chambers arranged in one to one and a half whorls with depressed sutures and angular periphery. The trochospire may be set laterally with respect to the axis of the uncoiled adult stage. The marginal chamber part presents an exoskeleton of a coarse and short polygonal network covered by a thin imperforate wall. The vertical partitions are equal in length; there is generally one horizontal partition (rafter) per chamber, while in the last chambers of fully grown specimens there may be two. The main part of the test consists of 5-8 rectilinear broad and low chambers that increase in width during ontogeny. There are mostly four to five chambers per last 0.5 mm axial length, rarely three. The maximum observed value for test length is 1.3 mm, and 0.61 mm for the width. The foramina are initially single interiomarginal becoming multiple in the rectilinear stage confined to the inner part of the septa. The test wall thin, imperforate, and finely agglutinated. The septa are distinctly thicker than the marginal chamber wall. Dimorphism might be present, but is insufficiently known. [details]
