Material – 69 specimens.

Description – Shell large (SL: 20–61). Spire low, outline concave to straight. Spiral whorls striate. Shoulder rounded to angulate. Body whorl elongate conical, outline concave, smooth with fine ridges on the lower third. Subsutural flexure asymmetrically curved. Colour pattern consisting of spiral stripes of square to rectangular patches.

Remarks – The Letkés specimens slightly differ from the lectotype (designated by KOHN 1982; figured on The Conus Biodiversity Website : biology.burke. washington.edu/conus). Some with higher spire of straight outline and somewhat sigmoid body whorl are close to L. antiquus elatospirata ( SACCO 1893, pl. 3, fig. 13), others agree with the holotype of L. subacuminatus (figured by HALL 1964, pl. 21, figs 5, 8–9). The morphology of L. antiquus is very close to that of Lithoconus leopardus (Röding, 1798) , the type species of the genus, therefore Lamarck’s taxon is classified here as Lithoconus .
