Malva cathayensis, a wild medicinal and edible Malvaceae species, lacked genomic data until now. In this study, we presented its first complete chloroplast genome (158,793 bp), featuring a quadripartite structure: 87,215 bp LSC, 20,766 bp SSC, and two 25,406 bp IRs. The genome contains 129 genes (85 protein-coding, 36 tRNA, 8 rRNA) with 37.1% GC content. Phylogenetic analysis revealed two Malva clades, with M. cathayensis grouping alongside M. crispa, M. verticillata, and M. parviflora. This study provides essential molecular data for Malva's evolutionary relationships and diversification, enabling future comparative genomic research in this genus.

Tulipa uniflora (L.) Besser ex Baker (1874) is distributed throughout China, Mongolia, and Russia (Siberia). This study reports the complete chloroplast genome sequence of T. uniflora based on high-throughput sequencing. The genome has a natural quadripartite structure and is 152,254 bp long with 36.5% GC content. It has 98 unique genes, including 4 rRNA genes, 29 tRNA genes, and 75 protein-coding genes. A total of 77 single-sequence repeats were identified, mostly in intergenic spacer regions. Anticodon recognition patterns revealed 19,717 codons in the protein-coding genes. Based on the whole chloroplast genome, T. uniflora was separated early from Tulipa species.

Garcinia xanthochymus is renowned for sweet, water-rich pulp fruits. Despite some phytochemical analyses highlighting its economic and medicinal value, research on its phylogeny is scarce. To fill this void, we sequenced the first chloroplast genome of G. xanthochymus. The genome was 157,688 bp long with a typical quadripartite structure, consisting of two IR (27,017 bp each), a LSC (85,998 bp), and a SSC (17,656 bp). It contained 125 unique genes, including 80 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Forming a distinct branch, G. pedunculata, G. subelliptica and G. mangostana showed the closest phylogenetic relationships.

The species Pisidia striata is predominantly distributed along the southeastern coast of China and belongs to the shallow-water crab family Porcellanidae. The complete mitochondrial genome of P. striata, which spans 15,357 bp and contains 13 protein-coding genes, 22 tRNAs and 2 rRNAs, is presented in this study. The nucleotide composition reveals A (37.81%), T (35.48%), G (9.75%), and C (16.96%). Phylogenetic analysis demonstrates a close relationship between P. striata and P. serratifrons within the Pisidia clade with robust bootstrap support values. This mitochondrial genome will be a significant supplement for the genus Pisidia and whole mitogenome phylogenetic analysis provided insights into further evolutionary research of Porcellanidae.

The complete mitochondrial genome sequence of Torodora canaliculata has been obtained based on the Illumina next-generation sequencing technology, which is currently the first reported mitogenome in the subfamil Torodorinae. The mitogenome is 15,590 bp in length, consisting of 13 PCGs, 22 tRNAs, 2 rRNA genes and one non-coding A + T rich control region. The phylogenetic tree constructed based on the maximum likelihood (ML) methods using the whole genome sequences does well support for the sister branch relationship between T. canaliculata and Issikiopteryx taipingensis. The complete mitogenome of T. canaliculata will provide useful genetic information for the evolutionary relationship of the Gelechioidea.

In this study, we report the complete mitochondrial genome sequence of Toxopneustes pileolus (Lamarck, 1816), which is the first complete mitochondrial genome of this genus Toxopneustes. The mitochondrial genome is 15,711 bp in length and includes 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and one non-coding control region (D-loop). Phylogenetic analysis based on mitochondrial genomes suggested a potential close relationship between the genus Toxopneustes and the genus Lytechinus. This study provided valuable genetic data for T. pileolus and contributed to the exploration of the phylogenetic relationships within the family Toxopneustidae.

Hibiscus moscheutos, a perennial herb in the Malvaceae family, has medicinal properties but lacks molecular data. This study sequenced and analyzed its first complete plastome using next-generation sequencing. The 160,208 bp circular plastome has a typical quadripartite structure with 130 genes and 36.93% GC content. Phylogenetic analysis showed that H. mutabilis is sister to H. taiwanensis. This study provides essential molecular data for future research on Hibiscus phylogeny, taxonomy, and evolution.

The mitochondrial genome of Rhinogobius wuyiensis Li & Zhong, 2007 was initially assembled using sequencing data from the Illumina HiSeq platform (San Diego, CA), resulting in a circular mitogenome of 16,502 base pairs with a pronounced A + T nucleotide bias. Maximum-likelihood (ML) and Bayesian inference (BI) revealed the phylogenetic relationships within the genus Rhinogobius, indicating that R. wuyiensis is closely related to a clade comprising R. maculagenys, R. shennongensis, R. niger, and R. lentiginis. This study enriches genetic resources and advances the understanding of phylogenetics within the genus Rhinogobius.

Chlaenius naeviger Morawitz, 1862 is a ground beetle species with a potential as a biological control agent for agricultural pests. In this study, we sequenced and annotated the complete mitochondrial genome (mitogenome) of C. naeviger, which is 16,594 bp in length and comprises 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and an A + T rich region. Furthermore, we used the nucleotide sequences of 13 PCGs to reconstruct a maximum likelihood phylogenetic tree of the family Carabidae, which revealed a close relationship between Chlaeniini and Panagaeini (BP 100). Our findings shed light on the phylogenetic relationships among the harpaline tribes.

The complete mitochondrial genome of Thyridosmylus trimaculatus Wang, Du et Liu, 2008 with 16,011 bp long is reported here. It contains 37 annotated genes and the control region. Most protein-coding genes (PCGs) started with typical ATN, except ND1 initiated with TTG. Most PCGs terminated with the complete stop codons (i.e. TAA and TAG), while COX2, ND4, ND5, CytB terminated with T-tRNA, and ND2, ND3 terminated with TA-tRNA. Phylogenetic analysis revealed that T. trimaculatus were closely related to T. langii. Osmylinae were recovered as the sister group to Spilosmylinae + Protosmylinae. Osmylidae were demonstrated being the sister group to Nevrorthidae + Sisyridae.
