The complete mitochondrial genome of Metaphycus eriococci (Timberlake) (Hymenoptera: Encyrtidae)

Abstract

The complete mitochondrial genome of the Metaphycus eriococci (Timberlake, 1916) (Hymenoptera: Encyrtidae) was obtained via next-generation sequencing. This mitochondrial genome is 15,749 bp in length with 37 classical eukaryotic mitochondrial genes and an A + T-rich region. All the 13 PCGs begin with typical ATN codons. Among them, 12 PCG genes terminate with TAA, only one with TAG. All of the 22 tRNA genes, ranging from 58 to 72 bp with typical cloverleaf structure except for trnS1 and trnE, whose dihydrouridine arm forms a simple loop. A dramatic gene rearrangement with a large inversion of six protein-coding genes (nad3-cox3-atp6-atp8-cox2-cox1) also found in M. eriococci. Phylogenetic analysis highly supported the monophyly of Pteromalidae, Eupelmidae, and Encyrtidae are sister groups. Within Encyrtidae, Metaphycus eriococci and Aenasius arizonensis are close to each other.
