Abstract

: The genus Pyramidula presents a Palearctic geographical distribution, being described in Spain four species not distinguishable from an anatomical point of view. In the present study, we compare our samples along with the previously recognized species P. rupestris , P. saxatilis , P. pusilla , P. cephalonica ; P. jaenensis , and P. chorismenostoma by means of molecular studies. Also, we compared P. jaenensis from the studied locality with P. rupestris according to the shell shape by means of geometric morphometric methods. The analysis of the Thin-Plate Spline graph showed that P. jaenensis presented an expansion on the growth to the first whorls and the apex, whereas the height of the body whorl was moderately contracted, while in P. rupestris the opposite was found. We found significant differences between both species based on shell shape. We also provide new information about morphological features that could be used in future studies of this genus attempting to stablish a baseline to test whether the Spanish species are cryptic species or not. The present study also extends the distribution of Pyramidula to Madrid, Spain,

基于综合分类学方法的jaenensis (Pyramidula jaenensis, Clessin, 1882)(腹足目:金字塔科)分类重新定义

金字塔属呈现古北的地理分布，在西班牙被描述为从解剖学的角度无法区分的四种。在本研究中，我们将我们的样本与以前认识的物种P. rupestris, P. saxatilis, P. pusilla, P. cephalonica进行了比较;用分子方法研究贾奈泊鱼和羽状瘤泊鱼。此外，我们还利用几何形态计量学的方法，根据壳的形状，比较了研究地点的贾颡鱼(P. jaenensis)与秘鲁颡鱼(P. rupestris)。薄板样条图的分析表明，日本稻向第一轮和顶端的生长呈扩张趋势，而体轮的高度呈适度收缩趋势，而鲁氏稻则相反。我们发现两种物种在外壳形状上存在显著差异。我们还提供了关于形态特征的新信息，这些信息可以用于该属的未来研究，试图建立基线来测试西班牙种是否为隐种。本研究还将皮拉米杜拉的分布范围扩大到西班牙马德里，

期刊介绍： Scientific peer-reviewed journal INVERTEBRATE ZOOLOGY publishes original papers, reviews and brief communications on morphology, anatomy, embryology, taxonomy, phylogeny, and ecology of any group of invertebrates from protistans to lower chordates. INVERTEBRATE ZOOLOGY accepts manuscripts in English or Russian and publishes them in printed and electronic versions. The Russian translations of English titles, abstracts and figure captions of the papers written by non-Russian authors can be provided by the editors. Invertebrate Zoology invites authors to publish extended monographic manuscripts after usual reviewing procedure. The monographic manuscripts can include up to 400 thousand letters and be prepared in English or in Russian. Accepted monographic manuscripts will have priority to be published in the nearest issue of the journal.
