Abstract: 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.

Description of hitherto unknown fundatrices of Stomaphis graffii and S. longirostris (Hemiptera, Aphididae, Lachninae) https://dez.pensoft.net/article/1127/ Deutsche Entomologische Zeitschrift 61(1): 31-36

DOI: 10.3897/dez.61.7185

Authors: Łukasz Depa, Mariusz Kanturski

Abstract: The hitherto unknown fundatrices of two large aphid species having a cryptic mode of life, Stomaphis graffii Cholodkovsky, 1894 and S. longirostris (Fabricius, 1787), are described from specimens collected in Poland. Key to identification of known fundatrices of European representatives of the genus Stomaphis is provided and the observed morphological features are discussed.
