Original Description

Large, robust; slightly elevated sinistral trochospire, extremely tight parallel and perpendicular to axis. Equatorial outline barely lobate; lateral outline oval. Chambers globular, extremely closely appressed, over 7 (12?) in total, 3! in final whorl; increase moderate until third-last chamber when much reduced. Dorsal view: chambers longer concentrically, barely inflated; sutures flush; intercameral sutures directed and curved posteriorly. Ventral view: chambers weakly inflated, mostly proximally; intercameral sutures radial to curved, adjacent pairs of sutures Oast--second-Iast and second-Iast--third-Iast; third-Iast--fourth-Iast and fourth-last--finaI) meet at opposite ends of very low slit-like umbilical aperture; umbilicus closed. Lateral view: dorsoperipheral shoulder not quite smoothly rounded; highest part of umbilical shoulder closer to umbilicus than if smoothly rounded, thus apertural face slightly steepened. Wall weakly cancellate with fairly large dense pores.

Size:
Length, 310 µm; width, 330 µm; height, 255 µm.

Etymology:
Greek, ana, back again; the second component refers to 'Globigerina venezuelana Hedberg'.
