Vestalenula cylindrica的成虫和幼虫的形态测量瓣膜变异性分析[Straub，E.W.，1952.第三纪埃辛根和乌尔姆的微古生物学研究。D.多瑙Geologisches Jahrbuch 66，433-524.] Götzendorf-Pischelsdorf（下奥地利州，上中新世）的化石。这些数据进行了比较，从Mushenka（斯洛伐克，上中新世）和Boliqueime（葡萄牙南部，更新世）。来自奥地利和斯洛伐克的标本在形态上非常相似。相比之下，中欧人群（来自奥地利和斯洛伐克）和葡萄牙人之间的明确形态差异被确定，在瓣膜形状和大小。来自葡萄牙的瓣膜更长，并且比奥地利和奥地利的标本表现出更高的变异性。考虑到最近在法国南部出现的一个新的Vestalenula物种，这些形态上的差异可以被解释为微观进化的变化，这可能发生在中新世和现在的欧洲人口之间。
A morphometric valve variability analysis of adults and juveniles of Vestalenula cylindrica [Straub, E.W., 1952. Mikropaläontologische Untersuchungen im Tertiär zwischen Ehingen und Ulm a. d. Donau. Geologisches Jahrbuch 66, 433–524.] from Götzendorf–Pischelsdorf (Lower Austria, Upper Miocene) is presented. The data are compared with those from Studienka (Slovakia, Upper Miocene) and from Boliqueime (southern Portugal, Pleistocene). Specimens from Austria and Slovakia are very similar in their morphology. By contrast definite morphological differences between the Central European populations (from Austria and Slovakia) and the Portuguese one are identified, in both the valve shape and size. The valves from Portugal are more elongated and show a higher variability than the Austrian and Slovakian specimens. By considering the occurrence of a new Recent species of Vestalenula in southern France, these morphologic differences could be interpreted as micro-evolutionary changes, which could have occurred between the Miocene and the present time within the European populations.
