Molecular phylogeny of the inquiline cynipid wasp genus Saphonecrus Dalla Torre and Kieffer, 1910 (Hymenoptera: Cynipidae: Synergini)

Ongoing research in east and south east Asia has revealed many undescribed species of the inquiline cynipid genus Saphonecrus, suggesting that the phylogenetic relationships within this group are even more complicated than previously thought. Results of the Bayesian reconstruction of the Synergus complex of species are presented based on analysis of a segment of nuclear 28S D2 and mitochondrial cytochrome c oxidase I gene sequences.

The genus Saphonecrus appears to be a polyphyletic group with very distinct lineages. One lineage is associated with Synophrus in the Western Palaearctic on section Cerris oaks. Another involves the type species of SaphonecrusS. connatus (Hartig), and represents a distinct and probably early-diverging lineage with a Palaearctic distribution on white oaks. The third main lineage is predominantly Asian, and associated with oak-related Fagaceae including LithocarpusQuercus subgenus Cyclobalanopsis and Quercus section Cerris. This third lineage shows large diversity, and also includes the genus Ufo and the European lineage of S. undulatus Mayr and S. haimi Mayr. The Palaearctic species of the genus Synergus are recovered as a distinct unit, but its sister group relationship remains unresolved. Most of the new taxa are presented here as molecular operational taxonomic units (MOTUs), with formal descriptions in progress.
