Type material. Lectotype: NHMW 1949/0005/0042a, Lăpugiu de Sus ( Romania), SL: 38.0 mm, MD: 15.3 mm, illustrated in Hoernes & Auinger (1891, pl. 43, fig. 12), designated by Švagrovský (1982: 414); the same specimen was designated as lectotype again by Nikolov (1994: 56), who was unaware of the paper by Švagrovský (1982), figs 11C 1 –C 3, 3O. Paralectotype: NHMW 1949/0005/0042b, Lăpugiu de Sus ( Romania), SL: 35.5 mm, MD: 14.4 mm, illustrated in Hoernes & Auinger (1891, pl. 43, fig. 13), figs 11D 1 –D 3.

Studied material. NHMW 2016 /0177/0972, 1 spec., Lăpugiu de Sus ( Romania); NHMW 1875 /0009/0032, 4 spec., Lăpugiu de Sus ( Romania) .

Revised description. Shell medium-sized, solid, moderately slender fusiform with conical spire, apical angle 35–40°. Protoconch not preserved. Teleoconch of at least ten whorls. Early teleoconch whorls with broad smooth subsutural spiral cord and beaded suprasutural band crossed by two delicate spiral cords, separated by strongly concave mid-portion. Sculpture only slightly changing during ontogeny with appearance of indistinct tubercles on subsutural cord. Suture narrowly incised, linear. Last whorl ~60% of total height; subsutural collar narrow bearing blunt spines that strengthen and become pointed on last half whorl. Subsutural ramp broad, concave, delimited by tubercular shoulder; convex below, moderately constricted at base. Siphonal fasciole weakly swollen, slightly twisted. Sculpture of bifid shoulder cord bearing about 26 small tubercles, mid-whorl and peribasal cords slightly narrower, tubercular. Two tubercular perifasciolar cords of similar strength. Secondary and tertiary spirals in interspaces and over base and fasciole. Aperture moderately narrow, pyriform. Outer lip not thickened, with numerous lirae within, extending deep within aperture. Anal sinus deep, moderately narrow, asymmetrically Ushaped, with apex at mid-ramp. Siphonal canal moderately long and wide, twisted, slightly deflected to the left with shallowly notched tip. Columella strongly excavated in adapical third, straight below, weakly twisted at fasciole, smooth. Columellar and parietal callus thick, sharply delimited, forming broad callus rim, separated from fasciole by pseudumbilical chink.

Discussion. This species is characterized by its conical spire, deeply concave subsutural ramp, the presence of two spiral cords that overrun the suprasutural row of tubercles on the spire, and the double perifasciolar cords, which is not seen in any other Paratethyan clavatulid. The spirals that run over the suprasutural row of tubercles on the spire continue on the last whorl to make the tubercles on the shoulder cord bifid, another feature not seen in other Paratethyan clavatulids. The relatively simple sculpture of the early teleoconch whorls allows a separation from the otherwise somewhat similar ‘ Clavatula ’ sophiae ( Hoernes & Auinger, 1891) , which has a tripartite sculpture of beaded cords.

Paleoenvironment. Occurrences from Borský Mikuláš ( Slovakia) point to inner neritic, agitated paleoenvironments in the photic zone, characterized by soft sea-bottom ( Švagrovský 1981a).
