Revised description. Medium sized, very slender cyrtoconoid shell of up to 16 teleoconch whorls; apical angle ~20–22°, later decreasing to ~10°. Protoconch unknown. Early teleoconch whorls conical, flat sided, with prominent, more or less orthocline axial ribs, separated by narrower interspaces. Subsutural band moderately developed, delimited by shallow groove. Abapically; distance between axial ribs widens; interspaces between ribs bearing relatively broad, flat spiral cords separated by narrow grooves; subsutural band strengthens, becomes convex, bearing widely spaced axial ribs; spiral groove delimiting subsutural band deepens, punctate between axials. Whorl profile weakly convex below subsutural band with periphery just below mid-whorl. Suture distinctly incised. Last whorl moderately high, ~30% of total height, slightly convex. Base convex, moderately constricted. Fasciole broad, moderately prominent, delimited adapically by weak carina. Aperture narrow. Columella moderately excavated in adapical half. No columellar fold. Columellar callus forming broad, thin rim, poorly delimited from base. Anal canal narrow, weakly incised. Outer lip thin. Siphonal canal moderately long, narrow, slightly twisted, moderately deeply notched at tip.

Discussion. See above for a separation from Strioterebrum basterotii ( Nyst, 1845) . Strioterebrum volhynianum is reminiscent of S. exbistriatum ( Sacco, 1891a) with which it co-occurs at several Paratethyan localities. They are distinguished by the more prominent subsutural cord of S. volhynianum and the more delicate spiral sculpture of S. exbistriata .

Paleoenvironment. Found in shallow marine assemblages (e.g., Szob, Várpalota) and middle to outer neritic depositional settings (e.g., Baden, Bad-Vöslau).

Genus Maculauger Fedosov, Malcolm, Terryn, Gorson, Modica, Holford & Puillandre, 2020

Type species. Terebra pseudopertusa Bratcher & Cernohorsky, 1985 [= Maculauger kokiy Pacaud & Lesport, 2020 ], original designation by Fedosov et al. (2020: 368). Present-day, Indian Ocean.

Original diagnosis. “ Small to medium-sized (<60 mm); typically, orange-brown with irregular maculations on subsutural band. Whorl outline flattened or gently convex. Subsutural band lightly ribbed or flattened, separated from lower portion of whorl by narrow groove or row of punctations. Axial and spiral sculpture of about equal strength, producing cancellate sculpture below subsutural band.” ( Fedosov et al. 2020: 368).

Discussion. Maculauger is difficult to define by conchological features alone. Fedosov et al. (2020) emphasized that axial and spiral sculpture is of equal strength. This feature is seen in some specimens of Maculauger scarabellii ( Coppi, 1876) (see Davoli 1977: pl. 2, figs 9, 10, 11) but does not occur in all specimens (see Davoli 1977; pl. 2, figs 7, 13, 14). Maculauger sophiae ( Hoernes & Auinger, 1880) lacks spiral cords as well, like the living Maculauger castigatus (A. H. Cooke, 1885) , which was included in the genus by Fedosov et al. (2020) based on molecular data. However, in their generic shell description of Maculauger they did not include the conchological characters seen in the ‘ castigata group’; i.e., well defined swollen subsutural band with coarse tubercles, sharply delimited by narrow groove, wide spaced ribs below, no spiral sculpture. In addition, UV light revealed a color pattern of blotches at the subsutural band of Maculauger sophiae ( Caze et al. 2010) , which is characteristic for some Maculauger species ( Fedosov et al. 2020). Maculauger sophiae and M. scarabellii are strikingly similar to Maculauger castigatus from the present-day Red Sea in shape and sculpture suggesting a close relationship. However, we stress that inclusion of this ‘ castigata group’ in Maculauger is based solely on molecular data presented by Fedosov et al. (2020). The shells are so strikingly different that it might warrant further molecular confirmation. This is the first record of Maculauger from the European Neogene.
