Complete mitochondrial genomes of two damselfly species in coenagrionidae and phylogenetic implications

Abstract

Agriocnemis femina (Brauer, 1868) and Ischnura senegalensis (Rambur, 1842) are two damselflies inhabiting paddy lands. As an intermediate predator, they play an important role in controlling certain crop pest and mosquitoes. In this study, we sequenced complete mitogenomes of these two species. The total length of mitogenomes is 15,936 bp in A. femina and 15,762 bp in I. senegalensis. Both of mitogenomes consist of 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and one control region. The close relationship between I. senegalensis and I. elegans was further proved by phylogenetic analysis. Our phylogenetic analysis indicated a clear two lineages in Coenagrionidae (Core and ridge-faced Coenagrionidae). Ridge-faced Coenagrionidae consisted of Megaloprepus caerulatus and Ceriagrion fallax. In core Coenagrionidae, Ischnura and Enallagma are most closely related; they formed one clade with Agriocnemis and then grouped together with Paracerion. Our study provides new genetic information for further study in phylogenetic analysis of Coenagrionidae.

Characterization of the nearly complete mitochondrial genome of ochraceous darkies, Euphaea ochracea Selys, 1859 (Odonata: Zygoptera: Euphaeidae) and phylogenetic analysis

“…The phylogenetic relationship of Euphaeidae obtained from the analyses is also consistent with other previous studies, where Euphaeidae is phylogenetically closer to the family Pseudolestidae (Jiang et al. 2021 ; Wang et al. 2021 ).…”

“… 2016 ; Jiang et al. 2021 ). Odonates are also excellent health indicators of aquatic ecosystems and are well-distributed in tropical and subtropical regions (Chee Yen and Mohamed Dawood, 2021 ).…”

Genetic variation and population structure of a widely distributed damselfly (Ischnura senegalensis)

“…The cultivation of rice might be a key factor in promoting gene exchanges among those populations. I. senegalensis is a common species found in rice fields (Hendawy et al, 2005; Jiang et al, 2021; Kandibane et al, 2005). India, South East Asian, and East Asia are the major rice cultivating areas in the world (Chandio et al, 2021).…”

“…Large areas of rice fields provide a suitable ecosystem for the breeding and dispersing of I. senegalensis (Pavithran, Chitra, and Ramanathan, 2020; Sugita et al, 2018). Investigations suggested that only several damselfly species were widely distributed in rice fields, including I. senegalensis (Jiang et al, 2021; Pavithran, Chitra, Arulprakash, and Sugumaran, 2020; Wakhid et al, 2020). During the season of rice cultivation, I. senegalensis could expand their population via large area of rice fields.…”
