Description Diagnosis: Hemigordiopsidae coiled as Hemigordiopsis (i.e. initially tightly streptospiral and later planispiral involute with lumen extending to umbilicus but with flosculinisation well developed) but with complete partitions denominated more or less abusively pillars, while they are probably regularly spaced protuberances attaining the top of the tube. Aperture terminal simple.
Occurrence: Midian/Dzhulfian boundary. Because of the association of Shanita with Chusenella in Oman (material in MONTENAT et al., 1977) and Neoschwagerina in Iran (material of P. MASSE, unpublished data), apparently preserved in situ, we considered Shanita as preferentially latest Midian than earliest Dzhulfian (compare with VACHARD et al., 2002). Characteristic of Cimmeria and Sibumasu terranes (see below the chapter palaeobiogeography).

Diagnosis Test large, up to 4.0 mm in diameter, subglobular, biumbilicate, proloculus followed by undivided enrolled second chamber that is streptospirally coiled in the early stage, then becomes planispiral, completely involute, with very wide and low chamber lumen that may be undivided in the early whorls, but in at least the later ones has numerous vertical pillars in alternating rows from umbilicus to umbilicus, or pillars may be more irregularly distributed; wall calcareous, thick, imperforate, recrystallized but probably originally porcelaneous; aperture terminal, slitlike, possibly subdivided by the pillars into shorter slits. U. Permian (Murgabian to Dzhulfian); Burma; Oman; Thailand; China; Turkey; Iran. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
