The complete mitochondrial genome of Syrista parreyssii (Spinola, 1843) (Hymenoptera: Cephidae) and its phylogenetic analyses.

The complete mitochondrial genome of Syrista parreyssii (Spinola, 1843) was described. The circular genome is 18,666 bp with an A + T content of 82.60%. It contains 37 genes and a 1921 bp control region. The CR- trnI (+)- trnQ (-)- trnM (+) cluster is rearranged as trnM (+)-CR- trnQ (-)- trnI (+) cluster. Phylogenetic analysis demonstrates that European Syrista and Asian Neosyrista were not sister groups. Neosyrista is a valid genus and should be reestablished. Moreover, a preliminary study based on COI showed there are at least three valid Syrista species within the European and Mediterranean regions. Whether the known Syrista parreyssii (Spinola, 1843) is a complex or there are more cryptic species needs further study.
