Morphological differences of upper lip shape were analyzed in seven Heterocypris species occurring in the Mediterranean region. Descriptive observations and morphometric analysis of upper lip length, height and maximum height position are given for 17 populations from the Pannonian Plain, Balkan Peninsula and Iberian Peninsula. We found high variation in relative upper lip measurements between the species, indicating that upper lip traits can be used as additional taxonomic characters. The most distinctive upper lip shapes were noted in H. exigua and H. gevgelica, while the greatest intraspecific variability was present in H. barbara, H. incongruens and H. rotundata. Previously described qualitative characters in the form of differently arranged patches of pseudochaetae on the upper lip surface were also observed.
对地中海地区出现的七种异星介属物种的上唇形状的形态差异进行了分析。给出了来自潘诺尼亚平原、巴尔干半岛和伊比利亚半岛的17个种群的上唇长度、高度和最大高度位置的描述性观察结果和形态测量分析。我们发现物种之间相对上唇测量值存在很大差异，这表明上唇特征可作为额外的分类学特征。在微小异星介和盖氏异星介中发现了最独特的上唇形状，而在巴氏异星介、不相符异星介和圆形异星介中存在最大的种内变异性。还观察到了以前描述的上唇表面伪刚毛排列不同形式的定性特征。
