Type material: Syntypes illustrated in Pereira da Costa (1866: pl. 3, figs 4–6); late Miocene , Tortonian; Cacella, Portugal. 

Studied material: 1 spec. NHMW 1855View Materials /0043/0002 Lăpugiu de Sus ( Romania). 

Illustrated material. Figs 8View FIGURE 8 I1–I4, 3J: Lăpugiu de Sus ( Romania): SL: 70.3 mm, MD: 43.6 mm, NHMW 1855View Materials / 0043/0002. 

Revised description. Moderately large shell with low spire; spire whorls weakly convex, smooth except for faint striae in the adapical thirds; suture impressed. Last whorl with additional faint spiral cords just above shoulder of last whorl. Subsutural flexure very shallow, weakly curved, moderately asymmetrical. Broadly rounded shoulder; last whorl elongate conical with weak constriction on base. No spiral cords on base. Siphonal fasciole weakly swollen, short; siphonal canal moderately wide, short. Colour pattern consisting of numerous delicate, continuous spiral stripes under UV light and about 10 narrow, whitish spiral bands in normal light (not clearly visible under UV light).

Shell measurements and ratios. SL: 70.3 mm, MD: 43.6 mm, spire angle: 130°, last whorl angle: 30°, LW: 1.61, RD: 0.69, PMD: 0.93, RSH: 0.10.

Discussion. Only a single specimen is available, which agrees well with the specimens illustrated by Pereira da Costa (1866) and Gonçalves & Monteiro (2012) in shape, the shallow subsutural flexure, the colour pattern and the faint concavity of the last whorl. This species is reminiscent of Kalloconus betulinoides ( Lamarck, 1810)  , from the late Miocene and Pliocene of the Proto-Mediterranean Sea, which differs in its even more elongate shell, the longer siphonal canal, the channelled suture, the striate early spire whorls and the prominent spiral cords on the base (based on NHMW collection).

Paleoenvironment. Unknown.

Distribution in Paratethys. Badenian (middle Miocene): Transylvanian Basin: Lăpugiu de Sus.

Proto-Mediterranean Sea and northeastern Atlantic. Tortonian: Cacela Basin, Portugal (Pereira da Costa 1866).
