Abstract
We sequenced the complete mitochondrial genome (mitogenome) for the North American Rhus gall aphid species Melaphis rhois. The mitogenome is 15,436 bp in length with a high A + T content of 82.7%, consisting of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region. Its gene order is identical to that of the eastern Asian species Schlechtendalia chinensis. All protein-coding genes start with a typical ATN codon and terminate with a TAA codon except COI and ND4 by a single T residue. All the tRNAs except tRNACys formed a clover-leaf secondary structure. The mitogenome phylogeny of Aphididae suggests that M. rhois is most closely related to the eastern Asian Rhus gall aphid S. chinensis with the present sampling scheme.
Highlights
The Rhus gall aphids belong to tribe Fordini (Hemiptera: Aphididae: Eriosomatinae) (Favret 2017) and were sometimes placed in subtribe Melaphidina (Remaudiere & Remaudiere 1997)
We obtained the mitogenome sequence of M. rhois using the shot-gun genome skimming method
The mitogenome of M. rhois has a base composition of A (44.6%), T (38.1%), C (11.3%), G (6.0%), and an A þ T content (82.7%)
Summary
The Rhus gall aphids belong to tribe Fordini (Hemiptera: Aphididae: Eriosomatinae) (Favret 2017) and were sometimes placed in subtribe Melaphidina (Remaudiere & Remaudiere 1997). KEYWORDS Rhus gall aphid; Melaphis rhois; Hemiptera; mitochondrial genome Melaphidina aphids are primarily an Asian group with only one species Melaphis rhois in North America, exhibiting a biogeographic disjunction between eastern Asia and eastern North America (Wen 1999; Zhang et al 1999; Ren et al 2013).
