The complete mitochondrial genome of the black field cricket, Teleogryllus oceanicus

Abstract

In this study, the complete mitochondrial genome sequence of the black field cricket, Teleogryllus oceanicus, with the total length of 15 660 bp is determined for the first time. This mitochondrial genome harbors 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNA), two ribosomal RNA genes (rRNA), and one control region (D-loop). The overall base composition is A (40.44%), C (17.12%), G (9.84%), and T (32.60%), so the slight A-T bias (73.04%) was detected. Phylogenetic analysis showed that T. oceanicus is closely related to T. emma that is also a member of the genus Teleogryllus.

Complete mitochondrial genome and taxonomic revision of Cardiodactylus muiri Otte, 2007 (Gryllidae: Eneopterinae: Lebinthini)

“…Despite the diversity of crickets and their allies, only a handful of mitogenomes are available today in databases (four in Song et al 2015). The families Gryllotalpidae, Myrmecophilidae and Schizodactylidae are each documented by one species, while the "true crickets", comprising three large families, namely Gryllidae, Phalangopsidae and Trigonidiidae (Chintauan-Marquier et al 2016), are represented only by five species belonging to a single subfamily (Gryllinae): Teleogryllus commodus (Wolff et al 2012), Teleogryllus oceanicus (Zhou et al 2015), Loxoblemmus equestris, Teleogryllus emma and Velarifictorus hemelytrus (Yang et al 2016a). The direct consequence of this is that the phylogenetic information of mitogenomes between and within cricket families has never been evaluated.…”
