Abstract
The complete mitochondrial genome of Isonychia kiangsinensis is a circular molecule of 15,456 bp in length, containing 2 rRNA genes, 13 protein-coding genes, 22 tRNA genes, and a control region. The AT content of the overall base composition is 62.9%. The length of the control region for I. kiangsinensis is 745 bp with 68.6% AT content. In BI and ML phylogenetic trees, Isonychia kiangsinensis was a sister clade to I. ignota and Isonychiidae was shown to be the basal clade of Ephemeroptera excluding Siphluriscidae. The monophyly of the families Isonychiidae, Heptageniidae, Viemamellidae, and Baetidae and the genus Isonychia were well supported.
Highlights
The family Isonychiidae is composed of one genus (Isonychia) and two subgenera (Isonychia and Prinoides) (Tiunova et al 2004; Tungpairojwong and Boonsoong 2011)
We sequenced the mitochondrial genome of Isonychia kiangsinensis and discussed its phylogenetic relationship within Ephemeroptera
Samples of I. kiangsinensis were collected in Jingning (275802200 N, 1193801000 E), Zhejiang province, China and identified by Dr Zhang
Summary
The family Isonychiidae is composed of one genus (Isonychia) and two subgenera (Isonychia and Prinoides) (Tiunova et al 2004; Tungpairojwong and Boonsoong 2011). KEYWORDS Ephemeroptera; mitochondrial genome; Isonychia kiangsinensis; phylogeny The phylogenetic relationship of Isonychiidae is controversial both in morphological and molecular aspects (Demoulin 1961; McCafferty and Edmunds 1979; Hebert et al 2003; Ogden and Whiting 2005; Sun et al 2006; O’Donnell and Jockusch 2008; Ogden et al 2009; Webb et al 2012; Saito et al 2016). We sequenced the mitochondrial genome of Isonychia kiangsinensis and discussed its phylogenetic relationship within Ephemeroptera.
