Seven new species of Hypselostomatidae are described from the Chinese province Guangxi: Angustopila dominikae Páll-Gergely & Hunyadi, sp. n., Angustopila fabella Páll-Gergely & Hunyadi, sp. n., Angustopila subelevata Páll-Gergely & Hunyadi, sp. n., Angustopila szekeresi Páll-Gergely & Hunyadi, sp. n., Hypselostoma socialis Páll-Gergely & Hunyadi, sp. n., Hypselostoma lacrima Páll-Gergely & Hunyadi, sp. n. and Krobylos sinensis Páll-Gergely & Hunyadi, sp. n. The latter species is reported from three localities. All other new species are known only from the type locality. Specimens nearly identical to the type specimens of Angustopila huoyani Jochum, Slapnik & Páll-Gergely, 2014 were found in a cave in northern Guangxi, 500 km from the type locality. Adult individuals of Angustopila subelevata sp. n. (shell height = 0.83-0.91 mm, mean = 0.87 mm) and Angustopila dominikae sp. n. (shell height of the holotype = 0.86 mm) represent the smallest known members of the Hypselostomatidae, and thus are amongst the smallest land snails ever reported. We note that Pyramidula laosensis Saurin, 1953 might also belong to Krobylos. Paraboysidia neglecta van Benthem Jutting, 1961, which was previously included in Angustopila, is classified in Hypselostoma.
多米尼卡窄口螺(Angustopila dominikae Páll-Gergely & Hunyadi, sp. n.)、法贝拉窄口螺(Angustopila fabella Páll-Gergely & Hunyadi, sp. n.)、亚高凸窄口螺(Angustopila subelevata Páll-Gergely & Hunyadi, sp. n.)、塞凯雷斯窄口螺(Angustopila szekeresi Páll-Gergely & Hunyadi, sp. n.)、群居高口螺(Hypselostoma socialis Páll-Gergely & Hunyadi, sp. n.)、泪滴高口螺(Hypselostoma lacrima Páll-Gergely & Hunyadi, sp. n.)和中华克罗比螺(Krobylos sinensis Páll-Gergely & Hunyadi, sp. n.)。后一种物种在三个地点被发现。所有其他新物种仅在模式产地被知晓。在距离模式产地500公里的广西北部一个洞穴中发现了与2014年的霍氏窄口螺(Angustopila huoyani Jochum, Slapnik & Páll-Gergely)模式标本几乎相同的标本。亚高凸窄口螺新物种(壳高 = 0.83 - 0.91毫米,平均 = 0.87毫米)和多米尼卡窄口螺新物种(正模壳高 = 0.86毫米)的成年个体代表了已知最小的高口螺科成员,因此也是有史以来报道的最小的陆生蜗牛之一。我们注意到1953年的老挝金字塔螺(Pyramidula laosensis Saurin)可能也属于克罗比螺属。先前被归入窄口螺属的1961年的疏忽副博伊西迪亚螺(Paraboysidia neglecta van Benthem Jutting)被分类到高口螺属。
