Description Diagnosis: Test minute, discoidal to or nearly nautiloid, with broadly rounded periphery and faintly to moderately umbilicate flanks. Coiling planispiral or skewed in the last whorls. Very large, spherical proloculus. Wall thin, bilayered, with darker and thin tectum and slightly lighter structureless primatheca. Chomata not observed. Aperture simple.
Occurrence: Cisuralian of NW Siberia (Sos nina, 1981). Bolorian of Iran (Leven & Gorgij, 2011). Yakhtashian-early Bolorian of Sinkiang, China (Gaetani & Leven, 2014). Questionable in the Carnic Alps (this study).

Diagnosis Test tiny, up to 0.6 mm in diameter, nautiloid with broadly rounded periphery, sides flattened to slightly umbilicate, proloculus relatively large for the size of the adult test, only three to five whorls present; wall thin, poorly differentiated, or may have weakly developed diaphanotheca, commonly recrystallized, secondary deposits may occur on the chamber floors, chomata poorly developed or lacking but may have rudimentary pseudochomata, aperture slitlike. L. Permian (Sakmarian); USSR: E. Siberia; Yugoslavia; Japan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]

Taxonomic remark Remarks: As indicated by Leven (2010b) and Vachard et al. (2013b), Zarodella can be emplaced at the base of the pamirinin lineage, whereas Grovesella Davydov & Arefifard, 2007 is transitional between schubertellinins and pamirinins and consequently, is located at the commencement of the superfamily Neoschwagerinoidea. Pamirinins are composed of Zarodella, Levenella Ueno, 1994; and Pamirina Leven, 1970a; they are ancestors of the misellinins Brevaxina Schenck & Thompson, 1940 and Misellina Schenck & Thompson, 1940, and, therefore, of the superfamily Neoschwagerinoidea (see Kobayashi, 1977; Ueno, 1991a, b, 1994; Leven, 2010b; Vachard et al., 2013b). The Levenella Zone is Yakhtashian in Japan (Ueno, 1991b); the Pamirina darvasica Zone is middle Kungurian (= lateYakhstashian) in age according to Davydov et al. (2013). For Angiolini et al. (2016), the Brevaxina Zone corresponds to the entire Bolorian regional stage and consequently to the late Kungurian of Davydov et al. (2013). The Misellina Zone corresponds to the early Kubergandian = late Roadian.
