Wetzeliella neocomica
Wetzeliella? neocomica Gocht, 1957, p.172–178, pl.19, figs.1–5; pl.20, figs.1–7; text-figs.7–16. Emendation: Helby, 1987, p.310–313, as Phoberocysta neocomica.
NOW Phoberocysta. Originally Wetzeliella?, subsequently (and now) Phoberocysta, thirdly Muderongia. Gocht, 1957, questionably included this species in Wetzeliella.
This species was listed in synonymy under Muderongia tomaszowensis Alberti, 1961, by Monteil, 1991, who considered Phoberocysta Millioud, 1969, to be a tax. jr. synonym of Muderongia Alberti, 1961. However, Wetzeliella (as Muderongia) neocomica must be retained as the tax. sr. synonym. Monteil in an Errata sheet accompanying Monteil, 1991, acknowledged this.
Monteil, 1991, emended the diagnosis of Muderongia tomaszowensis; in the Errata sheet Monteil gave the citation: "Muderongia neocomica Gocht 1957 comb. nov. and emend." This combination is not validly published since Monteil did not fully reference the basionym and the Errata sheet does not constitute effective publication.
Monteil, 1991, also listed in synonymy with Muderongia tomaszowensis the following taxa: Wetzeliella? neocomica forma circulata Gocht, 1957; Wetzeliella? neocomica forma cruciformis Gocht, 1957; and Wetzeliella? neocomica forma dedecosa Gocht, 1957.
Lentin and Williams, 1993, asssumed that Monteil, 1991, intended to treat all three formae as tax. jr. synonyms of the autonym of Wetzeliella? neocomica.
Holotype: Gocht, 1957, pl.19, fig.1; text-fig.7
Locus typicus: Ruehlertwist, Emsland, NW Germany
Stratum typicum: Hauterivian
Translation Gocht, 1957: LPP
Original description: Gocht 1957, p. 172-176
Diagnosis: Shell flattened, extremely variable in shape, generally more or less 4-5 sided, delicate. Closed edge rare; Shell all around mostly developing into bilayered and exteriorly closed projections, which may be located at several levels, but which are essentially limited to the region of the outer margin. Among them, an apical horn, two lateral horns, and an antapical horn smay often be clearly distinguished. Projections and horns often provided with pointed, blunt or trumpet shaped, flat protruberances or processes, which almost exclusively stand along the outline, and rarely on the surface. On the front and back sides projections or processes are sporadic. Along the margins of the apical and antapical horns, the protruberances are are often arranged alternatively. Lateral horns mostly slightly squat, broad- based, sometimes slightly bent, giving rise to a slightly V-shaped cross-section.
Projections and processes may be considerably reduced or extremely enlarged, as well as the horns, which may also partly be missing or be unrecognizable as such.
Exceptionally, denticulate ridges or idications of a transverse furrow occur on the shell.
Inner body delicate, with a more or less oval outline.
