Typematerial.

The type locality of Conus gainfahrenensis Hoernes & Auinger, 1879, considered to be junior synonym of M. mojsvari, is the middle Miocene locality Gainfarn in Austria. The type locality of Conus miocaenicusSacco, 1893, considered to be junior synonym of M. mojsvari, is the middle Miocene locality Pötzleinsdorf in Austria. Studiedmaterial. Syntypesand 1 spec.

Figs 25E1–E 2,26I, 17T: Pötzleinsdorf ( Austria): SL: 103.6 mm, MD: 60.3 mm, NHMW1847/0037/0024, illustrated in Hörnes (1851, pl. 2, fig. 1); Figs 25F1–F2,26J: syntype, Gainfarn ( Austria): SL: 87.2 mm, MD: 54.3 mm, NHMW1853/0010/0001, illustrated in Hoernes & Auinger (1879, pl. 3, fig. 2). Revised description.Moderately large to large shell up to 105 mmin height; about 10 teleoconch whorls. Depressed spire with initially moderately coeloconoid and later low conical outline; adapical half of spire whorls weakly concave, distinctly striate; abapical part convex, sometimes bulging. Subsutural flexure of medium depth, strongly curved, moderately asymmetrical; suture usually wavy and irregular. Shoulder weakly angulated; position of maximum diameter slightly below shoulder; last whorl regularly conical below periphery, not constricted. Surface smooth except for weak growth lines and indistinct, low spiral cords on base. Aperture moderately wide, anteriorly broadening; siphonal canal very short, wide, nearly straight; fasciole not well demarcated, weakly swollen with prominent growth lines; inner lip twisted. No colour pattern preserved.
Shell measurements and ratios.n = 8 adultand subadult specimens: largest specimen: SL: 105 mm, MD: 63.8 mm, mean SL: 89.3 mm(σ = 11.2), mean MD: 53.7 mm(σ = 6.7), spire angle: µ = 132.3° (σ = 8.5°), last whorl angle: µ = 37.3° (σ = 2.1°), LW: µ = 1.67 (σ = 0.06), RD: µ = 0.66 (σ = 0.02), PMD: µ = 0.88 (σ = 0.02), RSH: µ = 0.09 (σ = 0.01).
Discussion.The very broad species concept of Hörnes (1851) united several species as Conus mercati, which were later recognized as distinct taxa by Hoernes & Auinger (1879)and Sacco (1893a). Monteiroconus mercatihas smooth spire whorls, whereas the Paratethyan shells variously placed on M. mercatiin the literature all have striate spire whorls (see Landau et al. 2013). The first available name for this mercati-like shells with conical spire (in contrast to M. daciae) and moderately elongate last whorl is Conus mojsvari Hoernes & Auinger, 1879. Later, Sacco (1893a)introduced Conus mercatii miocaenicaas variation name for the specimen illustrated by Hörnes (1851, pl. 2, fig. 1) without discussing its relation with C. mojsvari. The only difference between the syntypesof Monteiroconus mojsvariand the syntypeof M. miocaenicusis the larger size, more elongate last whorl and the slightly gradate last two spire whorls of M. miocaenicus.As there are also intermediate specimens between both morphotypes, we consider M. miocaenicusa very large specimen of M. mojsvariand treat it as subjective junior synonym. The single specimen, described by Hoernes & Auinger (1879)as Conus gainfahrenensis(NHMW 1855/0045/ 0351), is just an aberrant specimen of M. mojsvariwith a slight constriction in the middle of the last whorl. Paleoenvironment.All occurrences reflect shallow water environments, partly with sea grass meadows and coral patches ( Zuschin et al.2007; Kovács & Vicián 2013).
