Original Description
È una Pulvinulina, che appare specificamente inseparabile dalla P. menardi. Accanto al disegno inedito leggesi: 'jamais plus de 5 loges', il quale carattere la distinguerebbe dalla P. menardi quale vedesi riprodotta dalla fig. 1 (tav. CIII) di Brady. Ma le fig. 2 e 3 dello stesso Brady dimostrano che la P. menardi puo presentarsi anche con cinque sole camere nell'ultimo giro. [Fornasini 1906]

Extra details from original publication
Synonym: Rotalia nitida d'Orbigny, 1826, Ann. Sci. Nat., vol. VII [ p. 274, no. 31 (nomen nudum)].

General remarks 
- Although the name Rotalia nitida d'Orbigny was nomen nudum in 1826, it became available in 1906 when d'Orbigny's drawing of this species was published. In 1826, d'Orbigny had noted that his specimens of this species came from recent material collected from the coasts of the island of Ste. Helene, and, in the A. d'Orbigny collections in Paris, there exists a tube of specimens labelled "Rotalia nitida d'Orbigny., vivante, Ste. Helene."" Of the eight specimens present in this tube, one has been isolated and it is here illustrated (pI. 6, figs. 3a-c) and designated as lectotype of Rotalia nitida d'Orbigny 1906.
As will be seen from the illustration (pl. 6, figs. 3a-c), the lectotype of R. nitida d'Orbigny 1906 is almost identical to that of R. menardii Parker, Jones and Brady 1865 (see p. 31, pI. 6, figs. 2a-c) and we also believe it to be fully conspecific with  d'Orbigny 1839 (see p. 34, pl. 6, figs. la-c). [Banner & Blow 1960]"

Hello Jeremy,

As mentionned in your remarks above R. nitida is said to be a subjective junior synonym of G. menardii (which in turn should be accepted as G. cultrata which was formaly published before G. menardii = problem of d'Orbigny's plaster models not being accepted as a formal publication).

hmm - some of these d'Orbigny species are really tricky because not only are there complex nomenclatural problems but also species concepts problems. The extant species have been carefully revised by the SCOR working group but the Neogene is much more problematic. So, in this interval we are basically just compiling a record of existing usage not making any judgements.
