Species Blefuscuiana kuznetsovae Banner & Desai 1988



Diagnosis / Definition:
Banner & Desai (1988):
Test a low trochospire, completely evolute and flat or slightly concave on the spiral side, with six to eight chambers in the last whorl. On the spiral side,chambers are inflated, subglobular, approximately as high as long, intercameral sutures being depressed and radial or very slightly oblique. The spire opens slowly;on the spiral side the test diameter is 2.5-2.8 times the height of the last formed chamber. The umbilicus is broad (about 0.27 of the test diameter) and shallow; on this side, the sutures are depressed and radial. The aperture is a low arch, from the umbilicus to the periphery of the penultimate whorl, with a distinct porticus which broadens slightly posteriorly; discrete relict apertures and their portici are open for at least half of the last whorl. The wall is smooth and microperforate, the external openings of the perforations being 0.6-0.7µm in diameter, spaced at 1.3-5 µm distances.
Discussion / Comments:
Boudagher-Fadel et al. (1997):
Remarks: B. kuznetsovae has seven chambers abutting the umbilicus in the last whorl. Last chambers are inflated, subglobular (h/L = l approx.), and almost as high as long (L1 = L2). The umbilicus is broad (u/uh = 0.27 approx.) and shallow. The aperture is a low arch, from the umbilicus to the periphery of the penultimate whorl, with a distinct porticus which broadens slightly posteriorly; relict apertures and their portici are open for at least half of the last whorl.
