The article represents an overview of 29 biological species of the radicine snails (genera Ampullaceana Servain, 1882, Bullastra Bergh, 1901, Racesina Vinarski & Bolotov, 2018, Kamtschaticana Kruglov & Starobogatov, 1984, Myxas G.B. Sowerby I, 1822, Orientogalba Kruglov & Starobogatov, 1985; Peregriana Servain, 1882, Radix Montfort, 1810, and Tibetoradix Bolotov, Vinarski & Aksenova, 2018) recovered during our previous molecular taxonomic study (Aksenova et al. 2018a; Scientific Reports, 8: 11199). For each species, the following information is provided: scientific name, a (non-exhaustive) list of synonyms, type locality, type materials, shell and copulative apparatus morphology, distribution, and nomenclatural and taxonomic remarks. The colour images of shell(s) of each species are also given as well as illustrations of the copulatory apparatuses. We revealed a great conchological variation in the radicines, both intraand interspecific, alongside with striking uniformity in the structure of their copulatory apparatuses. The latter was once thought to be a reliable tool for species delineation and identification in this snail group. The total of 29 species characterised here represents, probably, only a subset of the global taxonomic richness of the radicine snails, which approaches 50 species.

对基因描述的radicine蜗牛（软体动物，腹足类，蛔虫科）进行分类评估

这篇文章概述了 29 种草本蜗牛（Ampullaceana Servain 属，1882 年，Bullastra Bergh，1901 年，Racesina Vinarski & Bolotov，2018 年，Kamtschaticana Kruglov & Starobogatov，1984 年，Myxasient GB1822 Starobogatov， , 1985; Peregriana Servain, 1882, Radix Montfort, 1810, and Tianzoradix Bolotov, Vinarski & Aksenova, 2018) 在我们之前的分子分类学研究中恢复 (Aksenova et al. 2018a; Scientific Reports, 8: 11199)。对于每个物种，提供了以下信息：学名、同义词（非详尽）列表、类型地点、类型材料、壳和交配器的形态、分布以及命名和分类注释。还给出了每个物种贝壳的彩色图像以及交配装置的插图。我们揭示了 radicines 的巨大贝壳学变异，包括种内和种间，以及它们的交配器结构的惊人一致性。后者曾被认为是该蜗牛群中物种划分和鉴定的可靠工具。此处表征的总共 29 个物种可能仅代表 radicine 蜗牛全球分类丰富度的一个子集，接近 50 个物种。后者曾被认为是该蜗牛群中物种划分和鉴定的可靠工具。此处表征的总共 29 个物种可能仅代表 radicine 蜗牛全球分类丰富度的一个子集，接近 50 个物种。后者曾被认为是该蜗牛群中物种划分和鉴定的可靠工具。此处表征的总共 29 个物种可能仅代表 radicine 蜗牛全球分类丰富度的一个子集，接近 50 个物种。
