Description Description: Test similar to Bradyina but with a wall homogeneous, dark, single and not alveolar.
Occurrence: Mikhailovian-earliest Voznesenian, Paleotethyan and Uralian (Moscow Syneclise; Donets Basin: C1 vf2-C1 sa; western and eastern slope of the Urals; Southern Timan; Kazakhstan; Tien Shan; Morocco; Algeria; England; Ireland; Southern France; Belgium; Poland; Turkey; Northern Afghanistan; Laos; Malaysia; Southern China; Japan; and Alaska). The LAD seems to be situated in the latest Serpukhovian/earliest Bashkirian of the Southern Urals (Pazukhin et al., 2002, p. 221) and perhaps Japan (Mizuno & Ueno, 1997, tabl. 2 p. 194). Discovered in the Mikhailovian of Akiyoshi area.
