Balashov I.A., Perkovsky E.E. 2020. An Eocene land snail Balticopta gusakovi gen.n., sp.n. (Stylommatophora: Gastrocoptidae) from Baltic amber // Invertebrate Zoology. Vol.17. No.1: 18–24 [in English].
ABSTRACT: We describe a monotypic genus from Priabonian (late Eocene) Baltic amber that has a moderately small (1.3x2.1 mm), ovate-conic shell with a large free aperture extended to the wall of the penultimate whorl. The parietal margin of the aperture is reflected and has a lip. The aperture is only partially visible because of dirt and an air bubble in the amber. At least one simple angular lamella is present relatively deep in the aperture.
