Original Description

Test trochoid, evolute dorsally, more or less involute ventrally and umbilicate. Early chambers subglobular, later becoming increasingly elongate in a radial direction. Wall generally hispid, uniformly perforate. lacking imperforate peripheral bands, carinae or costellae. Aperture ventral, interiomarginal, umbilical-extraumbilical, sometimes reaching periphery of the preceding whorl but not extending on to the dorsal surface or becoming equatorial. Test not biumbilicate. Apertures furnished with portici, but lacking tegilla or bullae. No supplementary or accessory apertures. but relict apertures may be present.



Extra details from original publication
Remarks. This subgenus differs from Praeglobotruncana (Praeglobotruncana) in lacking an imperforate peripheral band and in possessing radially elongate chambers in the adult. It differs from P. (Hedbergella) in possessing radially elongate adult chambers, and is related to that subgenus in the same way as Globorotalia (Hastigerinella) is related to G. (Turborotalia). lt diiTers from G. (Hastigerinella) in possessing characteristically Hantkeninid portici, and it may be distinguished from Plannomalina (Hastigerinoides) by its lack of an equatorial primary aperture and its uniumbilicate test. Hastigerine/la simplex Morrow 1934, and Hastigerinoides simplicissima Magnc and Sigal 1954. arc also considered to belong to Praeglobotruncana (Clavihedbergella).
