Anceps sarmates

Anceps sarmates (Eichwald, 1850) † = Trochus sarmates var. mediosarmates Kolesnikov, 1935 = Trochus sarmates var. akburunensis Kolesnikov, 1935 = Trochus trilineatus Simionescu & Barbu, 1940 = Trochus athanasiui Siminescu & Barbu, 1940 = Calliostoma nictans Volkova, 1974 Middle-late Miocene (Volhynian, Bessarabian): Eastern Paratethys Sea (Moldova, Romania, Bulgaria, Ukraine, Russia, Georgia). (Sladkovskaya 2017) Genus Callumbonella Thiele, 1924 Type species. Gibbula gorgonarum P. Fischer, 1884 [= Callumbonella suturalis (Philippi, 1836)], type by typification of replaced name. Present-day, E Atlantic, NE Atlantic, Mediterranean Sea. Diagnosis. Broad trochiform nacreous shell with nearly flat whorls, weakly incised suture and distinct basal angulation. Umbilicus fully sealed or reduced to narrow chink. Sculpture reduced to weak, faintly beaded spiral cords Remarks. Callumbonella is a deep-water genus (Malaquias et al. 2003). As most of the classical European Neogene outcrops represent shallow water environments, the fossil record of this genus might be biased. The oldest records come from the latest Zanclean-early Piacenzian (Landau et al. 2003). = Umbotrochus Thiele, 1924 (non Perner, 1904), type species: Gibbula gorgonarum P. Fischer, 1884 [= Callumbonella suturalis (Philippi, 1836)], type by monotypy.
