1969 Conus (Lithoconus) tietzei (Hoernes et Auinger) – ATANACKOVIĆ, p. 215, pl. 13, fig. 5.

Material – 114 specimens.

Description – Shell medium-sized (SL: 15–46). Spire of low to moderate height, outline concave. Spiral whorls striate. Sutural ramp of the body whorl flat, shoulder subangulate. Body whorl conical, outline straight to slightly convex, smooth with fine ridges at the base. Aperture wide. Subsutural flexure asymmetrically curved.

Remarks – The taxon was described from Szob and Lăpugiu by HOERNES & AUINGER (1879), and its validity was confirmed by CSEPREGHY-MEZNERICS (1956). The Letkés material agrees with the type, matches the specimen M 61.4800. in the collection of the Hungarian Natural History Museum, and resembles the specimen figured by ATANACKOVIĆ (1969). The species differs from Dendroconus berghausi in higher and concave spire, and in outline of the shoul- der. D. fuscocingulatus is a narrower form with rounded shoulder. M. mercati differs in higher spire and in longer body whorl.

Distribution – Bosnia, Romania (MM). Hungary: Diósd, Kemence, Letkés, Szob (MM).
