Mid-Cretaceous Burmese amber preserves an exceptionally diverse assemblage of operculate land snails. Here, two new diplommatinid species are described: Euthema convexispira Bichain et Páll-Gergely, sp. nov. and Eu. torokzselenszkyi Páll-Gergely et Szabó, sp. nov. Newly found specimens of two previously known species, Hirsuticyclus canaliculatus Yu, 2022 and Cretadiostoma caperatum Yu, Zhuo et Páll-Gergely, 2023, are described and illustrated; the specimen of the former is characterised by a distinctive spiral operculum, while that of the latter provides additional data on the morphology of the aperture and the proportions of the shell whorls. Furthermore, the article reports three specimens that are tentatively attributed here to the species Euthema cf. annae Balashov, 2021 and to the genera Euthema Yu, Wang et Pan, 2018 and Pulchraspira Yu, Salvador et Jarzembowski, 2021.
