REVISION OF DENTALINA SPINOSA D’ORBIGNY, 1846 AND NONIONINA BOUEANA D’ORBIGNY, 1846

Papp & Schmid (1985) indicated that the specimens in vials 37 and 76 of the Austrian collection did not correspond neither to Dentalina spinosa , nor to Nonionina boueana , as formerly listed under these numbers and names, and figured in d’Orbigny’s work (1846: 55, 108; pl. 2, figs 36, 37 and pl. 5, figs 11, 12, respectively). Therefore Papp & Schmid (1985: 34) concluded that: “Vial 37 contains 26 specimens which correspond to N. [ Nodosaria ] elegantissima . Plate 2, fig. 36 in d’Orbigny (1846) corresponds to none of these. We therefore unite this species with N. elegantissima ”. This means that they synonymized both names D. spinosa and N. elegantissima (d’Orbigny, 1846) ( Fig. 1 ), and, consequently, we think that it is a misidentification of D. spinosa .

They figured ( Papp & Schmid 1985: pl. 17, figs 1, 2) a specimen from vial 37 with the following caption: “ Nodosaria elegantissima (d’Orbigny) (= Dentalina spinosa d’Orbigny )”, but no typical reference material was presented.Moreover, Vespermann (1995) points out, as noted above, that this species needed to be revised.For Nonionina boueana ( Fig. 2 ), the second species under reconsideration in the present study, Papp & Schmid (1985: 46) remarked: “Vial 76 contains 51 well-sorted specimens; contrary to the illustration in d’Orbigny they are asymmetrical. Based on the illustration in d’Orbigny, this species was often interpreted as a broad form of N. [ Nonion ] scaphum; due to the test shape and aperture, we assign it to Hanzawaia ”. Thus, they retain Hanzawaia boueana (d’Orbigny, 1846) as the valid name of this taxon, and designated a lectotype (GBA 1981/03/138) in the Austrian collection, which is figured in their paper. This misinterpretation of the species Nonionina boueana was first pointed out by Revets (1996).
