A comparative morphometric study of the genus Drepanosiphoniella Davatchi, Hille Ris Lambers and Remaudière (Hemiptera: Aphididae: Drepanosiphinae)

Abstract The genus Drepanosiphoniella Davatchi, Hille Ris Lambers and Remaudiere, 1957 of the subfamily Drepanosiphinae (Hemiptera: Aphididae) is revised using comparative morphology of parthenogenetic and sexual generations. On the basis of thorough examination of morphological characters, a full species status of Drepanosiphoniella fugans Remaudiere and Leclant, 1972 stat. rev. is given, and supported by using statistical analysis – principal component analysis (PCA) and multiple discriminant analysis (canonical variates analysis). A new species, Drepanosiphoniella remaudierei sp. n. Wieczorek, is described and figured in detail on the basis of specimens collected in Morocco. Fundatrix, oviparous female and apterous male of Drepanosiphoniella aceris aceris Davatchi, Hille Ris Lambers and Remaudiere, 1957 are described and figured. Original keys to the identification of the known species and morphs of the genus Drepanosiphoniella as well as differences with related species are given. Notes about the distribution and host plants of the studied taxa are supplied. All species studied seem to be montane elements associated with Acer monspessulanum or its subspecies.
