Stworzewicz, Ewa & Prisyazhnyuk, Valentin A., 2006, A new species of Miocene terrestrial gastropod Gastrocopta from Poland and the validity of “ Pupa (Vertigo) suevica ”, Acta Palaeontologica Polonica 51 (1), pp. 165-170 : 167

Subgenus Sinalbinula Pilsbry, 1916

Diagnosis (after Pilsbry 1916).—Whitish, with plicae on a palatal callus. Parietal lamella straight inside, or curving towards the columella, its anterior end usually free, but sometimes the angular and parietal lamellae are concrescent into a single sinuous lamella. Columellar lamella horizontal, or with the inner end curved downward.

Remarks.—Although the subgeneric division of Gastrocopta is questioned by Solem (1988) and Pokryszko (1996), it is currently accepted by most authors (cf. Manganelli and Giusti 2000).
