Material. Three isolated teeth. NHMW 2025/0177/0033 (2).

Description. Two teeth (Pl. 6, figs 15a–b, 16a–b) possess a high principal cusp that arise from the center of a rounded base. The labial part overhangs the crown-root junction. The teeth correspond with the teeth illustrated by Jonet (1968, figs 7, 9 and 11).

Discussion. The generic placement of this species has been debated for decades. Here we follow the wellfounded opinion of Szabó et al. (2022).

Distribution. Middle Miocene, Paratethys ( Schultz 2013); Proto-Mediterranean, southern France ( Cappetta 1987).

Distribution in Portugal. Middle Miocene: (Langhian–Serravallian) Lower Tagus Basin ( Fialho 2015). Upper Miocene: (Tortonian) Algarve Basin, Cacela Fm. (this paper); (Messinian) Alvalade Basin, Esbarrondadoiro Fm. ( Balbino 1995; Antunes & Balbino 2003).
