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.

The mitogenome of Phallus dongsun comprises a circular DNA molecule of 59,243 bp with a GC It is a 59,243 bp circular DNA molecule with 25.74% GC content, containing 14 PCGs, 2 rRNAs, 25 tRNAs, and 15 introns. It features 19 SSRs and a codon bias toward A/T endings. All protein-coding genes show strong purifying selection (avg. Ka/Ks=0.049). Phylogenomic analysis reveals a well-supported clade with P. indusiatus and P. echinovolvatus as sisters. Incongruence with nuclear trees is attributed to past misidentification of Chinese specimens. This first complete mitogenome for P. dongsun provides a key genomic resource for future phylogenetic studies in Phallus.

Butis koilomatodon (Bleeker, 1849) is common in China, belongs to the family Butidae within the order Gobiiformes. The complete mitochondrial genome of B. koilomatodon was sequenced and characterized for the first time. The circular genome is 16,521 bp in length, comprising 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and one control region. The phylogenetic reconstruction based on the mitochondrial genome sequences revealed B. koilomatodon as sister to Butis melanostigma. This study could be beneficial for systematic studies on family Butidae.

Chamaecyparis obtusa 'Tetragona', a striking ornamental tree native to Japan, has been introduced into China for horticultural cultivation. This study presents the complete chloroplast genome of C. obtusa 'Tetragona'. With a total length of 127,429 bp, the complete chloroplast genome has an overall GC content of 35%. A total of 120 functional genes were annotated, including 83 unique protein-coding genes, 33 tRNA genes, and 4 rRNA genes. The phylogenetic analysis reveals a sister relationship between C. obtusa 'Tetragona' and Chamaecyparis obtusa var. obtusa.

Thaumatophyllum bipinnatifidum is a perennial evergreen herb belonging to the family Araceae and genus Thaumatophyllum. Its chloroplast genome has a total length of 169,027 bp, comprising a large single-copy region of 94,617 bp, a small single-copy region of 22,544 bp, and two inverted repeat regions of 25,933 bp. The chloroplast genome consists of 132 RNA components, including 87 protein-coding genes, 37 transfer RNAs, and eight ribosomal RNAs. Phylogenetic analyses revealed that T. bipinnatifidum clusters closely with Aglaonema and Zantedeschia. These findings provide valuable data for assessing the genetic diversity, species identification, and evolution of T. bipinnatifidum.

Pothos chinensis (Raf.) Merr., a medicinal herb widely used in Yao ethnomedicine, is reported here with its first complete chloroplast genome sequence. The assembled chloroplast genome is 163,354 bp in length and exhibits a typical quadripartite structure, consisting of a large single-copy region of 103,428 bp, a small single-copy region of 6,802 bp, and a pair of inverted repeat regions of 26,582 bp each. The genome contains 128 genes, including 86 protein-coding genes, 36 tRNA genes and 6 rRNA genes. Phylogenomic analysis of 15 Araceae species indicates that P. chinensis is most closely related to species of the genus Anthurium.

Yangxincai, a "highcalcium vegetable," is a hybrid of Phedimus aizoon L. and Phedimus kamtschaticus (Fisch., 1840), historically misidentified as P. aizoon L. owing to their morphological similarity. Uncertainty regarding its parentage has impeded official nomenclature and caused confusion in research. To clarify its maternal origin, we sequenced and assembled its complete chloroplast genome, 151,666 bp in length with a GC content of 37.73%, comprising LSC 83,128 bp, SSC 16,704 bp, and a pair of IRs (25,917 bp). A total of 128 genes were annotated,including 84 proteincoding, 36 tRNA, and 8 rRNA genes. Phylogenetic analysis of the maternally inherited chloroplast genome confirmed P. aizoon as the maternal parent, and we propose the corrected name Phedimus aizoon × kamtschaticus for this hybrid cultivar.

Pocillopora meandrina Dana, 1846 is a coral species widely distributed in the Indo-Pacific Oceans. Here, we report the first complete mitochondrial genome of P. meandrina from the South China Sea. The mitogenome is 17,422 bp in length, containing 13 protein-coding genes (PCGs), 2 ribosomal RNA genes (rRNAs), and 2 transfer RNA genes (tRNAs), with a GC content of 30.1%. Eleven PCGs start with ATG, and ten end with TAA. Phylogenetic analysis revealed that P. meandrina is closely related to other Pocillopora species. The study provides valuable molecular data for evolutionary and phylogenetic studies of Pocillopora.
