Ornatoraphidia flavilabris (Costa, 1851) is one of 15 snakefly species occurring in southern parts of Central Europe. It is a polycentric Mediterranean faunal element with refugia in the Apennine Peninsula and the Balkan Peninsula. Two phylogeographic questions are dealt with in this paper: (1) Is it possible to differentiate, morphologically or genetically, the Balkanic populations from the Italian? (2) Did the species reach Central Europe from the Balkan or Apennine Peninsula? These questions were investigated using morphological and molecular biological methods. No morphological characters were uncovered which could serve to differentiate specimens from either distribution center. However, differences were detected in cox1, cox3 and 28S genes which allow for a reliable differentiation. Central European populations were largely identical with populations from Italy, but distinctly different from specimens from Greece. This could lead one to assume that the species migrated from Italy to Central Europe, although colonization from the southeast would appear easier due to more favorable orographic conditions. This discrepancy may be explained by the apparent absence of O. flavilabris from the large central part of the Balkan Peninsula, so that a gap exists between the southern and northern areas inhabited by O. flavilabris. Moreover, the species does not occur in eastern parts of Europe. Thus it would be more probable to assume that the occurrence of the species in the northwest Balkan Peninsula can be traced to migrations from the Apennine Peninsula to areas north and northeast of the Adriatic Sea, where O. flavilabris may have colonized the southeast of Central Europe. A migration of Adriatomediterranean faunal elements from the northwest Balkan Peninsula to Central Europe might be of more significance than previously assumed.

Ornatoraphidia flavilabris (Costa) 的中欧种群来自哪里？（神经翅目、剑翅目、刺翅目）

Ornatoraphidia flavilabris (Costa, 1851) 是出现在中欧南部的 15 种蛇蝇之一。它是一个多中心的地中海动物群，在亚平宁半岛和巴尔干半岛有避难所。本文涉及两个系统地理学问题：（1）是否有可能在形态或基因上区分巴尔干人与意大利人？(2) 该物种是否从巴尔干半岛或亚平宁半岛到达中欧？使用形态学和分子生物学方法研究了这些问题。没有发现可用于区分来自任一分布中心的标本的形态特征。然而，在允许可靠区分的 cox1、cox3 和 28S 基因中检测到差异。中欧种群与来自意大利的种群基本相同，但与来自希腊的标本明显不同。这可能导致人们假设该物种从意大利迁移到中欧，尽管由于更有利的地形条件，从东南部的殖民似乎更容易。这种差异可能是由于巴尔干半岛中部大片地区明显没有 O. flavilabris，因此在 O. flavilabris 居住的南部和北部地区之间存在差距。此外，该物种不会出现在欧洲东部。因此，更有可能假设该物种在巴尔干半岛西北部的出现可以追溯到从亚平宁半岛迁移到亚得里亚海北部和东北部地区，在那里 O. flavilabris 可能已经在中欧东南部殖民。亚得里亚海地中海动物群元素从巴尔干半岛西北部迁移到中欧可能比之前假设的更重要。
