Daughter taxa (time control age-window is: 0-800Ma)Granddaughter taxa
Test planispirally enrolled and involute, biumbilicate, early chambers globular and inflated, later ones radially elongate, and final one or two chambers clavate, sutures distinct, depressed; wall calcareous, moderately coarsely perforate, radial, surface pitted; aperture equatorial, an interiomarginal arch bordered with a distinct lip, lateral extremities of the aperture commonly remaining open as relict supplementary apertures around the umbilicus as new chambers are added.
Eohastigerinella watersi
Eohastigerinella sp.

Test planispirally enrolled, biumbilicate, involute to evolute, lobulate in outline, chambers globular to somewhat elongate in partially evolute species, sutures depressed; wall calcareous, perforate, optically radial; aperture equatorial and interiomarginal, bordered by a narrow imperforate lip, broad and low to moderately arched, the lateral portions remaining open as relict supplementary apertures around the umbilicus when new chambers are added.

Test planispirally enrolled and involute, biumbilicate, early chambers globular and inflated, later ones radially elongate, and those of the final whorl long and tapering, resembling tubulospines; wall calcareous, finely perforate; aperture a low interiomarginal equatorial arch bordered by a distinct lip, lateral part of the aperture remaining open as relict supplementary apertures around the umbilicus on each side as new chambers are added.
Hastigerinoides alexanderi
Hastigerinoides atlanticus
Hastigerinoides clavatus
Hastigerinoides sp.

Planispiral, wall texture smooth except sometimes pustulose early chambers, weakly lobate with 6-9 chambers in final whorl.
Laeviella bentonensis
Laeviella bollii
Laeviella primuloides
Laeviella tururensis


Test planispiral throughout, biumbilicate, peripheral margin rounded to acute; wall micro-finely perforate and muricate throughout; coiling involute to evolute, chambers globular to axially compressed; may be uniapertural or biapertural with bordering lip. Differs from Laeviella by having a muricate rather than smooth test surface; differs from Polycamerella by lacking any infolding of the test wall along the sutural margin of biapertural portici.

Planohedbergella impensa

Planohedbergella multispina
Planohedbergella prairiehillensis
Planohedbergella subcarinata
Planohedbergella ultramicra
Planohedbergella yaucoensis


Differs from all species of Planohedbergella and Laeviella by having: (1) consistent presence of a biapertural final chamber bearing broad, low apertural slits that open along the outer margin of the umbilicus and are bordered by infolding tubular apertural flaps that usually project directly into the umbilicus, (2) a more weakly lobate peripheral outline, (3) the slowest, continuously log-linear chamber expansion rate (text-figs. 4a, 4e, 6), and (4) the greatest total number of chambers in the adult test (average = 23).

taxonomic rank: Family
Taxonomic discussion: Huber et al. (2022) discuss at length many of the species in this family, and establish the new genera Laeviella and Polycamerella
