Actinidia melliana is a unique Actinidia species whose genomic data is extremely lacking. In this study, we reported the complete chloroplast genome of A. melliana for the first time, which has a total length of 156,159 bp, consisting of a large single-copy (LSC) region of 90,525 bp, a small single-copy (SSC) region of 20,578 bp, and a pair of inverted repeat (IR) regions with 22,528 bp each. A total of 133 genes were annotated, including 84 protein-coding genes, 41 transfer RNA genes (tRNA) and 8 ribosomal RNA genes (rRNA). Phylogenetic analysis alongside 28 other species in the Actinidiaceae family revealed that A. melliana is most closely related to A. cylindrica var. cylindrica. This study provides new genetic resources for evolutionary studies of Actinidia and supports future efforts in species identification and conservation within the genus.

The clearwing moth Synanthedon namdoelegans Kim, Kim and Choi, 2025 (Lepidoptera: Sesiidae) was newly discovered in South Korea in 2024. We sequenced 15,578 bp-long complete mitochondrial genome of the species. It contained the trnQ-trnS2-trnM-trnI arrangement at the A + T-rich region and ND2 junction (the underline indicates counterclockwise direction) unique to tribe Synanthedonini. Phylogenetic analyses of 18 Cossoidea species supported the monophyly of each Synanthedonini and Synanthedon, and revealed a sister relationship between S. namdoelegans and Synanthedon bicingulata (Staudinger 1887). These data will be useful in taxonomic, molecular ecological, and pest management research.

The Zygaenidae family comprises diurnal moths recognized for their bright coloration and chemical defenses. Despite its ecological and evolutionary significance, mitochondrial genome (mitogenome) data remain scarce. Here, we present the mitogenome of Neochalcosia remota, the first to be elucidated in members of the Neochalcosia genus, in the Chalcosiinae subfamily. The complete mitogenome is 15,246 bp and contains the standard set of 37 genes, with 13 protein-coding genes (PCGs), 22 tRNAs, and 2 rRNAs, as well as an A + T-rich region. An inverted translocation of the trnE-trnS₁ block (underlined gene names indicate a counter-clockwise transcriptional direction), instead of the typical trnS₁ -trnE arrangement in Lepidoptera, present in all Zygaenidae species, was also detected in N. remota. Phylogenetic analyses based on the 13 PCGs and two rRNAs in the Zygaenidae strongly supported the monophylies of this family and its subfamilies (Chalcosiinae, Procridinae, and Zygaeninae), placing N. remota as a sister taxon to Eterusia aedea. As a new contribution to the mitogenome database, the mitogenome of N. remota could provide valuable genetic data leading to a diverse taxonomic hierarchy in phylogenetic studies.

We sequenced and annotated the complete mitochondrial genome of Aoria bowringii. The circular mitogenome is 17,054 bp in length and exhibits a strong A + T bias, with nucleotide composition A 47.71%, T 30.63%, C 16.00%, and G 5.67%. It contains the typical set of 37 metazoan mitochondrial genes, including 13 protein-coding genes (PCGs), 22 transfer RNA genes, and two ribosomal RNA genes, as well as a putative control region. A maximum-likelihood phylogenetic analysis based on 13 PCGs places A. bowringii as a highly supported sister species to its congener Aoria nigripes. This mitogenome provides a valuable molecular resource for future phylogenetic and population genetic studies of this insect pest.

Eriocrania semipurpurella alpina Xu, 1990 is a leaf miner of birch trees in Qinghai Province, China. The complete mitogenome of E. semipurpurella alpina was reported in this study. The mitogenome contains 15,107 base pairs. Its nucleotide composition is 40.5% A, 8.1% G, 40.1% T, and 11.3% C. The genome encodes a set of 37 genes, including 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and one control region. Phylogenetic analysis supports the monophyly and primitive origin of Eriocraniidae.

The chloroplast genome size of Cardamine leucantha L. is 155,040 bp, including a large single-copy (LSC) region of 84,258 bp, a small single-copy (SSC) region of 17,936 bp, and two inverted repeats (IRs) of 26,423 bp, with an overall GC content of 36.33%. The chloroplast genome encodes 130 genes, comprising 85 protein-coding genes, eight rRNA genes, and 37 tRNA genes. Phylogenetic analysis using maximum-likelihood estimation indicates that C. leucantha is closely related to other species within the Cardamineae genus. The data from this study provide genomic resources for phylogenetic genetics and resource development of C. leucantha.

The fungal genus Ganoderma recently expanded with the description of Ganoderma shanxiense L. Fan & H. Liu 2019. This study presents the complete mitogenome of the species. The 97,036-bp circular mitogenome contains 60 functional genes, including 14 standard protein-coding genes, 27 tRNA genes, two rRNA genes, and 17 non-conserved ORFs. Notably, 32 introns are identified within 10 genes, harboring 31 intronic ORFs. Phylogenetic analysis based on mitochondrial protein sequences robustly places G. shanxiense within the Ganodermataceae family. This mitogenome provides a critical molecular resource for future taxonomic and evolutionary studies of this economically and ecologically significant fungal genus.

The frog crab Lyreidus stenops Wood-Mason, 1887 is primarily distributed in the East China Sea, South China Sea, and waters surrounding Japan and Korea. Its mitogenome (GenBank: PV437595) is 15,461 bp in length and comprises 13 PCGs, 2 rRNAs, 22 tRNAs, and one non-coding control region. Nucleotide composition analysis showed a high AT content (70.4%). Phylogenetic analysis grouped L. stenops with Lyreidus tridentatus and Lyreidus brevifrons in a monophyletic clade, with the latter two species exhibiting close evolutionary relationships. This mitogenome sequence enriches the genomic dataset for the species of Lyreidus and will aid in resolving evolutionary dynamics within Raninidae.

In this study, a complete mitochondrial genome of Murina yushuensis, sampled from Sichuan, China, was sequenced using the Illumina NovaSeq 6000 S4 platform. Results showed that the mitochondrial genome was a circular structure with a total length of 16,520 bp, comprising 13 protein-coding genes, 22 tRNA genes, two rRNA genes and 1 control region. Phylogenetic analysis based on 13 protein coding genes from limited mitochondrial genome data of 10 species of Murina revealed that M. yushuensis is closely related to M. eleryi. This study provides genetic data for further taxonomic and phylogenetic researches on Murina bats.

Glischrochilus japonius is a type of forestry pest that causes damage to various garden plants. In this study, the complete mitogenome of G. japonius was sequenced for the first time., The circular mitogenome comprises of 15,357 bp with an AT content of 77.51%, including 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes and one control region. The genera of the analyzed beetles from Nitidulidae in phylogenetic relationships are monophyletic. The mitochondrial genome structure of G. japonius is stable and conformed, and resolving the phylogenetic relationships amongst the sap beetles requires continued accumulation and improvement of mitogenome data.
