Type material. Lectotype designated by Landau et al. (2013): specimen illustrated in Pereira da Costa (1866, pl. 4, fig. 7); Cacela Basin (Portugal); late Miocene, Tortonian. The type locality of Conus enzesfeldensis Hoernes & Auinger, 1879, considered to be a junior synonym of L. subraristriatus, is the middle Miocene (Badenian) locality Enzesfeld in Austria.
Studied material. 4 spec NHMW 1853/0010/0004, 4 spec. NHMW 1853/0010/0006, 6 spec. NHMW A1610, including specimen illustrated in Schultz (1998, pl. 29, fig. 8.), all Enzesfeld (Austria), 1 spec NHMW 1857 /0014/ 0 0 0 5, Steinebrunn (Austria), 2 spec. NHMW A 992, Grund (Austria).
Illustrated material. Figs 21 G1–G3: Enzesfeld (Austria): SL: 57.9 mm, MD: 29.8 mm, NHMW 1853 /0010/ 0006a; Figs.21 H: Enzesfeld (Austria), SL: 52.6 mm, MD: 27.9 mm, NHMW A1610; Fig. 17I: Enzesfeld (Austria): SL: 48.7 mm, MD: 25.3 mm, NHMW 1853 /0010/0006b.
Revised description. Medium-sized, solid shells; spire of medium height, cyrtoconoid; spire whorls very weakly convex, smooth; subsutural flexure shallow, weakly curved, moderately asymmetrical; last whorl elongate, roundly shouldered, straight-sided, position of maximum diameter at shoulder; hardly constricted at base; bearing few weak, finely beaded spiral cords at the anterior end in some specimens; aperture straight, relatively narrow, widening slightly abapically; siphonal canal short, straight; siphonal fasciole rounded, relatively well-developed; colour pattern under UV light of widely spaced, narrow brownish dots and dashes, coalescing into straight spiral lines forming three continuous fluorescing bands, separating two narrow regions lacking pigmentation.
Shell measurements and ratios. n = 13: largest specimen: SL: 80.4 mm, MD: 39.4 mm, mean SL: 54.3 mm (σ = 9.2), mean MD: 28.1 mm (σ = 4.2), spire angle: µ = 92.6° (σ = 2.9°), last whorl angle: µ = 34.6° (σ = 1.0°), LW: µ = 1.9 (σ = 0.06), RD: µ = 0.63 (σ = 0.02), PMD: µ = 0.84 (σ = 0.03), RSH: µ = 0.18 (σ = 0.02).
Discussion. The status of this species was discussed in detail by Landau et al. (2013), who designated the specimen illustrated by Pereira da Costa (1866, pl. 4, fig. 7) as lectotype of L. subraristriatus, which is conspecific with Conus enzesfeldensis Hoernes & Auinger, 1879.
Paleoenvironment. Typically found in shallow marine, sandy nearshore environments.
