Test free, small, elongate, early part flaring rapidly, with 4 to 5 pairs of biseriaUy arranged chambers followed by 2 or rarely 3 subglobular uniserial chambers, of somewhat lesser breadth than the preceding biserial stage; sutures distinct, slightly depressed, nearly horizontal; wall calcareous, finely perforate, surface smooth; aperture in the biserial stage at the base of the final chamber, terminal in the uniserial stage of the adult test, produced on a short fragile neck which is commonly broken.


Size: Length of holotype 0.25 mm.

Extra details from original publication
Remarks: Tubitextularia laevigata, new species, is closest in appearance to T. midwayensis (Cushman) with which it is associated. It differs in the larger and more flaring test, more globular uniserial chambers and the smooth rather than hispid wall surface.
