Diagnosis Test trochospiral, biconvex to planoconvex, chambers slightly inflated, sutures moderately oblique on the spiral side, curved and radial on the umbilical side, foliar extension at the umbilical margin of the chamber, umbilicus filled with one to three large granules or plugs that may fuse with the folium, periphery angular, interior with paries proximus as an arched plate that attaches to the chamber floor and extends both forward and backward to produce a foliar chamberlet at the umbilical margin, dividing the septal foramen into one part that communicates with the main chamber cavity and a second part that opens into the foliar chamberlet; primary aperture interiomarginal, extending from the umbilicus to the peripheral carina, secondary aperture on the umbilical side near the base of the folium, allowing the foliar chamberlet to communicate with the exterior, in species that do not have a completely isolated foliar chamberlet, the secondary aperture may also communicate with the adjacent chamber in front of the paries proximus. M. Eocene to Holocene; cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
Taxonomy Hansen and Revets (1992): The nomenclatorial history of this species is very confused.
D’Orbigny failed to give either a description or a drawing, effectively
demoting the species to a nom. nud. The species name turbo became
available for the first time by the publication of Carpenter, Parker and
Jones (1862), in which a description of the species is given by Parker and
Jones (p. 204), but without an illustration. Thus, Parker and Jones are
deemed to have instated the species turbo, their description constituting an
indication (ICZN art. 12, paragraph b). The fact that the subgeneric name
‘Trochuline’ was given in French by d’Orbigny makes it an unavailable
name. Ehrenberg (1839) used the name Trochulina in a list, but without
description, author or illustration, rendering it once again a nom. nud.
Trochulina first became available in the work of Basset (1885), since the
assignation of a valid species name to a new genus-group name constitutes
an indication.
Unknown source:
Trochulina was considered to be a junior homonym of a coral genus by the same name but Levy et al (1980, 1986) showed that there was no valid attribution of a coral to this name and thus d'Orbigny's foraminiferal genus is retained and is a senior synonym of Discorbina Parker & Jones, 1862 which has the same type species.
