Type material. Syntype, illustrated by Sacco (1893b, pl. 11, fig. 10), Museo Regionale di Scienze Naturali, Torino (BS.038.08.003), Turin Hills, early Miocene, Burdigalian. The type locality of Conus subcoronatus Boettger, 1887  , considered to be a junior synonym of P. gastaldii  , is the middle Miocene (Badenian) locality Lăpugiu de Sus in Romania.

Studied material. 1 spec. SMF XII.2246 a, Lăpugiu de Sus ( Romania). 

Illustrated material. Figs 33View FIGURE 33 F1–F3: SMF XII.2246 a coll. O. Boettger ex G. Schmidt 1885, SL: 50.1 mm, MD: 26.8 mm, Lăpugiu de Sus ( Romania); holotype of Conus subcoronatus Boettger, 1887  ; picture Sigrid Hof; courtesy Ronald Janssen, section Malacology, Senckenberg Forschungsinstitut Frankfurt / Main. 

Revised description. Moderately large and robust shell with low spire; early spire whorls tuberculate just above suture. Spire whorls striate, weakly convex with wide, blurred nodes (= pseudo-nodes sensu Tucker & Tenorio 2009); suture undulose. Subsutural flexure shallow, moderately curved, strongly asymmetrical. Rounded shoulder with blurred nodes; position of maximum diameter slightly below shoulder; last whorl elongate, faintly ventricose, weakly constricted. Aperture and siphonal canal largely destroyed; siphonal fasciole indistinctly swollen. Few prominent spiral cords on base. No colour pattern preserved.

Shell measurements and ratios. Holotype: SL: 50.1 mm, MD: 26.8 mm, spire angle: 112°, last whorl angle: 32°, LW: 1.87, RD: 0.63, PMD: 0.95, RSH: 0.15.

Discussion. Tucker & Tenorio (2009) placed this rare species in Pseudonoduloconus  based on the conspicuous spire sculpture; this was followed by Kovács & Balász (2016), who treated the Paratethyan Pseudonoduloconus subcoronatus  as distinct species. The illustration in Boettger (1887) is misguiding and suggests a broader shell with slightly opisthocline and very prominent nodes. In fact, the holotype is a rather slender shell with low spire, which does not differ from the Italian Burdigalian morphotype described by Sacco (1893b, pl. 11, fig. 13) as Conus gastaldii supraproducta  . Therefore, we consider Conus subcoronatus Boettger, 1887  to be a subjective junior synonym of Conus gastaldii Michelotti, 1847  . It is not surprising that Boettger (1887) did not recognise the synonymy because the first figures of Conus gastaldii  were published much later by Sacco (1893b).

This species is distinguished from P. austriacus ( Hoernes & Auinger, 1879)  by its distinctly more slender outline, the less constricted base, the narrower and higher spire and the more swollen “pseudo-nodes”.

Paleoenvironment. Unknown.

Distribution in Paratethys. Badenian (middle Miocene): Transylvanian Basin: Lăpugiu de Sus ( Romania) ( Boettger 1887).

Proto-Mediterranean Sea and northeastern Atlantic : Burdigalian (early Miocene): Turin Hills ( Sacco 1893b); Aquitaine Basin: Léognan, Mérignac, Saint-Paul-lès-Dax ( France) ( Peyrot 1931); middle Miocene (Langhian): Langhian  : Aquitaine Basin: Manciet ( France) ( Peyrot 1931, as Conus subnocturnus, d’Orbigny, 1852  ).
