Description Test conical, trochospiral, with a planar to slightly depressed face. Umbilical face depressed to planar or forming more or less developed umbilical pivots (Globotetrataxis, some Tetrataxis). Mode of life attached to vagile, epiphytic on algae or corals. Four or five chambers in each whorl. Undivided chambers, or with secondary partitions (Valvulinella, Abadehella). Aperture in the umbilicus, occasionally protected by a micro-aquarium. Wall thin dark microgranular, thick with the hyaline microgranular always as the outer layer and only located in the umbilicus, and not on the flanks. Occurrence. Late Tournaisian (MFZ6)–Changhsingian; generally cosmopolitan. Triassic “tetrataxids” need further studies; Jurassic forms as Mohlerina Bucur, Senowbari-Daryan & Abate, 1996, are closely related to Tetrataxidae (Schlagintweit 2012). (Vachard and Le Coze (2022)).

Diagnosis Test conical, trochospiral, spiral side evolute, umbilical side involute; few to many chambers per whorl, secondary partitions may result in many tiny chamberlets; wall microgranular calcareous, may have one or two distinct layers; aperture umbilical. L. Carboniferous (Tournaisian) to U. Permian. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
