Type material. Holotype: PAL 2019.246.1., HNHM, Department of Paleontology and Geology, SL: 19.0 mm, MD: 11.8 mm, Bánd, Hungary, Figs 38A View FIGURE 38 1 –A View FIGURE 1 2 View FIGURE 2 .

Revised description. Small, stocky biconical shell; apical angle 72°. Protoconch worn, conical of about two whorls. Teleoconch of up to four whorls. Suture narrowly incised, superficial, shallow undulating. Early teleoconch whorls with broad subsutural ramp and rounded shoulder placed just above abapical suture. Axial sculpture of eight widely spaced ribs, fading over subsutural ramp. Spiral sculpture of indistinct adis, IP, abis; P1 prominent forming rounded nodes on shoulder. Last whorl short, attaining 80% of total height; with broad, weakly concave subsutural ramp, rounded shoulder, rapidly contracting below. Eight widely spaced, broad axial ribs, fading over subsutural ramp. Spiral sculpture simple of prominent adis, IP and abis, P1–P6, ADP and MP of subequal strength except for slightly more prominent P1. Cords separated by slightly narrower, weakly scabrose interspaces. Tertiary cord between abis and P1. Fasciole weakly swollen, delimiting very shallow pseudoumbilicus. Aperture ovate; outer lip thickened by terminal varix with subobsolete ID and weak and rounded D1–D6; bifid D2. Anal canal weakly incised. Siphonal canal moderately long, open, moderately narrow, slightly bent to the left. Columella straight, smooth. Columellar callus forming narrow, adherent rim.

Discussion. This species is only known from the holotype and is characterized by its small size, stocky biconical shape and simple spiral sculpture. It is unlikely that this specimen represents a subadult shell of one of the other Paratethyan Ocenebrinae and we follow Kovács (2020) in treating it as distinct but very rare species.

Paleoenvironment. The mollusk assemblage from Bánd indicates shallow marine environments with corals (own data, M.H.).
