The present study aims to clarify the confused taxonomy of von Frauenfeld, 1862 and Gittenberger, 1980. Revision of Iberian micro snails is severely hindered by uncertainties regarding the identity of the oldest Iberian species, von Frauenfeld, 1862. In this paper, we clarify its taxonomic status by designating a lectotype from the original syntype series and by describing its internal and external shell morphology. Using SEM-EDX, we attempt to identify the area of the type locality cave more precisely than "a cave in Spain". The shell described and illustrated by Gittenberger (1980) as appears not to be conspecific with the lectotype shell, and is considered a separate species, Jochum, Prieto & De Winter, was described from various caves in NW Spain. Study of the type material reveals that these shells are not homogenous in shell morphology. The holotype shell of is imaged here for the first time. The paratype shell, illustrated by Gittenberger (1980) from a distant, second cave, is described as Jochum, Prieto & De Winter, The shell selected here as lectotype of , was also considered a paratype of by Gittenberger (1980). Since this specimen is morphologically very similar to topotypic shells of , the latter species is considered a junior synonym of (). The internal shell morphology of all these taxa is described and illustrated using X-ray Micro Computer Tomography (Micro-CT).
本研究旨在厘清1862年冯·弗劳恩费尔德和1980年吉滕贝格尔所提出的混乱分类法。伊比利亚微型蜗牛的分类修订工作因1862年最早的伊比利亚物种——冯·弗劳恩费尔德的身份不确定而受到严重阻碍。在本文中，我们通过从原始同模式系列中指定一个选模式，并描述其内外壳形态来厘清其分类地位。利用扫描电子显微镜-能量色散X射线光谱仪（SEM-EDX），我们试图比“西班牙的一个洞穴”更精确地确定模式产地洞穴的位置。吉滕贝格尔（1980年）描述和图示的壳 似乎与选模式壳不同种，被认为是一个单独的物种，约胡姆、普列托和德温特， 是从西班牙西北部的各个洞穴中描述的。对模式标本的研究表明，这些壳在壳形态上并不一致。 的正模壳在此首次成像。吉滕贝格尔（1980年）从一个较远的第二个洞穴图示的副模壳被描述为约胡姆、普列托和德温特， 此处选为 的选模式的壳，吉滕贝格尔（1980年）也将其视为 的副模。由于该标本在形态上与 的地模壳非常相似，后一个物种被认为是 的次异名（ ）。使用X射线微计算机断层扫描（Micro-CT）对所有这些分类单元的内壳形态进行了描述和图示。
