Abstract: In this paper we apply an integrative approach combining morphometric and molecular analyses to explore parasitoids of the Praon dorsale-yomenae s.str. complex. These parasitoids occur in natural and agricultural ecosystems throughout the Palaearctic and parasitize aphid hosts belonging to the tribe Macrosiphini. The P. dorsale-yomenae species complex represents a morphologically cryptic group, consisting of several hidden taxa with specific host adaptations and distributions. For the morphometric analyses we used a large dataset comprising 230 female specimens that emerged from 30 different species of aphid hosts throughout the Palaearctic. The molecular analysis included a reduced dataset of 44 specimens that emerged from 19 aphid hosts. The mitochondrial cytochrome oxidase subunit I (COI) and the nuclear second expansion segment of the 28S rRNA gene (28SD2) were used to estimate a genetic diversity within this complex. Although all Praon species clustered closely together in the 28SD2 tree, confirming their close relatedness, the molecular characterization based on COI identified five clearly separate taxa with sequence divergences in the range of 4.7-8.9%. These taxa also exhibited significant differences in forewing shape as revealed by geometric morphometric analyses. Classical morphometric analyses revealed the length of m-cu vein as a new taxonomic character, but suggested that one commonly used trait, the color pattern of the Rs. +. M and m-cu veins, cannot be used for species distinction as it was highly variable in one of the taxa. Based on the combined morphometric and genetic data, we confirm the species status of Praon dorsale, P. yomenae, P. longicorne and P. volucre, and describe and illustrate a new parasitoid species of the dorsale-yomenae group, i.e. Praon staticobii n.sp. associated with Staticobium limonii on Limonium angustifolium. © 2014 Elsevier GmbH.
