Revised description. Medium-sized olivoid shells; pointed apex with tuberculate early spire whorls; later spire whorls weakly convex to nearly flat, striate, forming a high, nearly straight-sided conical to weakly cyrtoconoid spire. Subsutural flexure shallow, moderately curved, moderately asymmetrical. Very indistinct shoulder coinciding with slight angulation and position of maximum diameter; last whorl moderately elongate, weakly ventricose, not constricted. Siphonal canal very short, moderately wide, straight; fasciole very weak and indistinct; few thin spiral threads on base. Colour pattern under UV light consisting of wide-spaced spirals of long dashes, intercalated by 1–2 weaker spirals of shorter dashes. If uppermost shell layer is eroded, these spirals are underlain by a dense pattern of spirals covering the entire shell.

Shell measurements and ratios. n = 11: largest specimen: SL: 44.9 mm, MD: 19.5 mm, mean SL: 33.7 mm (σ = 1.8), mean MD: 14.9 mm (σ = 2.6), spire angle: µ = 71.5° (σ = 3.1°), last whorl angle: µ = 33.8° (σ = 1.1°), LW: µ = 2.3 (σ = 0.1), RD: µ = 0.58 (σ = 0.03), PMD: µ = 0.87 (σ = 0.03), RSH: µ = 0.23 (σ = 0.03).

Discussion. The strong spiral pattern on the syntype illustrated by Hoernes & Auinger (1879) is somewhat misleading, as it represents a specimen with corroded uppermost shell layer. These spirals are just a colour pattern and do not represent a spiral sculpture as suggested by Halaváts (1884) and Strausz (1966). The stout, robust specimen with somewhat ventricose last whorl, illustrated by Atanacković (1969, 1985) as Conus praelongus  , might represent another species. Lautoconus praelongus  differs from the slightly similar Leporiconus suessi ( Hoernes & Auinger, 1879)  , Leporiconus transsylvanicus ( Hoernes & Auinger, 1879)  and Conus  s.l. sturi Hoernes & Auinger, 1879  in its higher conical spire, shorter last whorl and lower position of the shoulder.

Paleoenvironment. No information.

Distribution in Paratethys. Badenian (middle Miocene): Eisenstadt-Sopron Basin: Forchtenau ( Austria) ( Sieber 1956); Transylvanian Basin: Lăpugiu de Sus ( Romania) ( Hoernes & Auinger 1879); Dacian Basin: Staropatica ( Bulgaria) ( Kojumdgieva & Strachimirov 1960).
