Type material. Syntype NHMW 1854 /0035/0046, Lăpugiu de Sus ( Romania), illustrated in Hoernes & Auinger (1879, pl. 1, fig. 23) ; 10 syntypes NHMW 1858 /0035/0008, Lăpugiu de Sus ( Romania) ; middle Miocene, Badenian (Langhian). The type locality of Conus fusiformis Halaváts, 1884 , considered to be a junior synonym of C. olivaeformis , is the middle Miocene (Badenian) locality Hidas in Hungary.

Illustrated material. Figs 35A 1 –A3: syntype, Lăpugiu de Sus ( Romania): SL: 24.5 mm, MD: 12.6 mm, NHMW 1858/0035/0008; Figs 30 Q, 35B1–B3: syntype, Lăpugiu de Sus ( Romania): SL: 21.9 mm, MD: 10.4 mm, NHMW 1854/0035/0046, illustrated in Hoernes & Auinger (1879, pl. 1, fig. 23).

Revised description. Small subcylindrical shells; high conical protoconch comprising c. 3 whorls; mammillate spire of medium height, with weakly tuberculate whorls; later spire whorls flat to weakly convex, forming conical to cyrtoconoid spire; suture narrow but impressed, very irregular. Surface glossy, smooth except for delicate growth lines, not striate. Subsutural flexure shallow, moderately curved, moderately asymmetrical. Shoulder indistinct to rarely subangulate. Narrow spiral grooves on base, delimiting broader cords. Siphonal fasciole very short, moderately swollen, poorly demarcated from thin and narrow inner lip. Moderately narrow aperture, adapically distinctly narrowing; siphonal canal moderately wide, short. Colour pattern under UV light consisting of three indistinct spiral bands of blotches, which are composed of densely spaced spiral dashes; additional dashes appear between these bands.

Shell measurements and ratios. n = 7: largest specimen: SL: 24.5 mm, MD: 12.6 mm, mean SL: 22.3 mm (σ = 2.0), mean MD: 11.2 mm (σ = 1.0), spire angle: µ = 87.7° (σ = 6.1°), last whorl angle: µ = 36.6° (σ = 2.7°), LW: µ = 2.0 (σ = 0.08), RD: µ = 0.6 (σ = 0.02), PMD: µ = 0.87 (σ = 0.03), RSH: µ = 0.16 (σ = 0.05).

Discussion. The spire height and shape are variable and the pointed apex and the tuberculate early spire are usually eroded. Hall (1966) listed this well-defined species as a synonym of Lautoconus ponderosus ( Brocchi, 1814) , which was probably a mistake. Lautoconus ponderosus is much larger, broader and has a distinctly more conical last whorl.

Halaváts (1884) described this species as Conus fusiformis . This name is preoccupied by Conus fusiformis Lamarck, 1810 and Conus fusiformis Pease, 1861 . Halaváts (1884) discussed similarities with Lautoconus praelongus ( Hoernes & Auinger, 1879) and Strausz (1966) considered this taxon a subspecies of L. praelongus . Both species differ in the much lower spire, the more ventricose and cylindrical last whorl, and the incised suture of L. olivaeformis . The holotype of Conus fusiformis Halaváts, 1884 was stored in the collection of the Geological and Geophysical Institute of Hungary in Budapest but seems to be lost (pers. comm. Klára Palotás). The specimen illustrated by Halaváts (1884) does not differ from L. olivaeformis and we consider it to be a subjective junior synonym of Conus olivaeformis . Therefore , no replacement name for the preoccupied C. fusiformis is necessary.

Distribution in Paratethys. Badenian (middle Miocene): Pannonian Basin: Hidas, Letkés, Pécsszabolcs ( Hungary) (Halaváts 1884; Kovács & Vicián 2013);? southern Pannonian Basin: Miljevići, Hrvaćani ( Bosnia and Herzegovina) ( Atanacković 1985); Transylvanian Basin: Lăpugiu de Sus, Coşteiu de Sus ( Romania) ( Hoernes & Auinger 1879; Boettger 1902).
