The complete mitochondrial genomes of three grasshoppers, Asiotmethis zacharjini, Filchnerella helanshanensis and Pseudotmethis rubimarginis (Orthoptera: Pamphagidae)

► Three Pamphagidae mitogenomes harbor the typical organization in Caelifera. ► F. helanshanensis is closer to P. rubimarginis by comparative analysis of mitogenome. ► The monophyly of Pamphagidae is certified by using four Pamphagidae mitogenomes. ► The relationship among some subfamilies within Caelifera is resolved using mitogenome.
