To delve deeper into the phylogenetic relationships within Cicadellidae and the taxonomic ar-rangement of Evacanthinae, our study focuses on the mitochondrial genome sequencing of five Nivanini species: Extensus latus、Concavepiana hamulusa、Sophonia nigrilineata、Sophonia mi-crostaina and Sophonia fuscomarginata. This research marks the first sequencing of the complete mitogenomes for the genus Extensus, revealing mitogenome lengths between 15,610 and 16,032 base pairs and encompassing 37 typical genes. The A+T content of Nivanini ranged from 72.5% to 78.7%, which is consistent with that of other sequenced Evacanthinae species. All transfer RNAs (tRNAs), except for trnS, exhibited a typical clover secondary structure, while trnS (AGY) lacked dihy-drouridine (DHU) arms. With regard to protein-coding genes, all started with ATN codons, except for atp8, and most of them use TAA or TAG as termination codons. Using the Bayesian inference and maximum likelihood methods, a phylogenetic tree based on all 37 genes was constructed, with a total of 57 Cicadellidae species and 2 outgroups included as research objects. The analyses con-firmed the monophyletic nature of each subfamily, highlighting Deltocephalinae as the oldest, dis-tinctively parallel to the others.
