Illustrated material. Figs 11View FIGURE 11 G1–G3, 3P: holotype, Lăpugiu de Sus ( Romania), SL: 50.4 mm, MD: 27.1 mm, NHMW 1854/0035/0041; Figs 11View FIGURE 11 H1–H3: Gainfarn ( Austria), SL: 49.6 mm, MD: 27.5 mm, NHMW 1855/0045/ 0 358.

Revised description. Medium-sized shells with low conical to broad coeloconoid spire; early spire whorls nearly flat, later whorls weakly convex with last spire whorl often slightly more convex; spire whorls smooth; suture channelled. Subsutural flexure shallow, weakly curved, moderately asymmetrical. Spire passing via a rounded shoulder into conical to weakly ventricose last whorl; position of maximum diameter close below shoulder. Last whorl faintly constricted; prominent to weak spiral grooves may appear on lower third; siphonal canal short; siphonal fasciole weak and indistinct. Aperture moderately narrow, posteriorly narrowing and only weakly broadening anteriorly. Colour pattern poorly preserved, but seems to consist of densely spaced continuous spirals.

Shell measurements and ratios. n = 10 adult specimens: largest specimen: SL: 59.3 mm, MD: 34.1 mm, mean SL: 49.8 mm (σ = 4.6), mean MD: 27.6 mm (σ = 2.9), spire angle: µ = 115.2° (σ = 8.1°), last whorl angle: µ = 34.6° (σ = 2.5°), LW: µ = 1.8 (σ = 0.1), RD: µ = 0.64 (σ = 0.03), PMD: µ = 0.9 (σ = 0.02), RSH: µ = 0.1 (σ = 0.03).

Discussion. Differs from Lautoconus steinabrunnensis  in the rounded shoulder, convex spire whorls, lower spire and the higher position of the maximum diameter. Its aperture is narrower especially in the posterior part.

Paleoenvironment. Shallow marine environments; at least at Gainfarn, the species was associated with seagrass.
