s.l. is a complex of taxa traditionally regarded as members of . It has a wide Mediterranean range, extending in the north to Central and Eastern Europe, and in the east to the Crimea, the Caucasus, and the Western Caspian region. Molecular phylogenetic data support placement of the complex in the genus . The present study investigated the phylogeny, phylogeography and morphological variability of the complex across its distribution range to reveal the main trends in genetic and morphological differentiation in this group. The results of the morphological analyses demonstrated some degree of differentiation, with ssp. , ssp. , and ssp. more or less well defined, whereas ssp. , ssp. , and ssp. can be hardly distinguished from each other using morphology. Analyses of the complex based on nrITS revealed a tendency towards a geographic differentiation into Western, Eastern, and Turkish groups. Phylogenetic and phylogeographic analyses of the same set of specimens using concatenated plastid markers L-F, 16, and A-H demonstrated a low resolution between the complex and , as well as among the taxa within the complex, which can be interpreted as evidence of an incomplete lineage sorting or hybridization. The evolutionary processes responsible for incongruence in phylogenetic signals between plastid and nuclear sequences of the morphologically well-defined species and were most likely localized in the Eastern Mediterranean. A possibility of rare gene exchange between the complex and the group of is revealed for the first time.
s.l. 是一个传统上被视为……成员的分类群复合体。它在地中海地区分布广泛，向北延伸至中欧和东欧，向东延伸至克里米亚、高加索地区和里海西部区域。分子系统发育数据支持将该复合体置于……属中。本研究调查了该复合体在其分布范围内的系统发育、系统地理学和形态变异性，以揭示该类群遗传和形态分化的主要趋势。形态分析结果显示出一定程度的分化，其中……亚种、……亚种和……亚种或多或少界限分明，而……亚种、……亚种和……亚种在形态上几乎难以相互区分。基于nrITS对该复合体的分析揭示了一种地理分化趋势，形成了西部、东部和土耳其类群。使用串联质体标记L-F、16和A-H对同一组标本进行的系统发育和系统地理学分析表明，该复合体与……之间以及该复合体内的分类群之间分辨率较低，这可解释为不完全谱系分选或杂交的证据。形态上明确的物种……和……的质体与核序列之间系统发育信号不一致的进化过程最有可能发生在地中海东部。首次揭示了该复合体与……类群之间存在罕见基因交换的可能性。
