Description
Lantschichites was elevated to generic status by RAUZER-CHERNOUSOVA & FURSENKO (1959, *1509, p. 212), where it was also regarded as including Parabollilonia SKINNER & WILDE, 1954, in synonymy. TUMANSKAYA gave the following diagnosis: The new subgenus Lantschichtes differs from the genus Codonofusiella by the different form of its shell: by its elongated, almost cylindrical form and broadly rounded sides at the poles. The septal folding is considerably more developed and septa occupy almost all of a volution. Similar features are: the small size of the shell, the endothyroid structure of the early volutions, the small dimensions of the embryonic chamber and, principally, the same kind of straightening and expansion of the terminal volution as in the genus Codonofusiella. Age. Upper Permian." She compares the subgenus to forms described by SCHUBERT (1915, *1693A, p. 78) from Timor as Fusulina weberi, which were referred by THOMPSON (1949, *1923, p. 186) to Palaeofusulina DEPRAT, 1912. I cannot determine all of the morphological features of Lantschichites significant for generic determination from TUMANSKAYA'S illustrations of the type-species. V.Perm., USSR.
