Pachylophus belongs to the subfamily Chloropinae, the second most diverse subfamily of Chloropidae. However, there have been few complete mitochondrial genomes of Chloropinae reported in the public database. Consequently, we sequenced and annotated the complete mitochondrial genome of Pachylophus rufescens (de Meijere, 1904). The whole mitochondrial genome is 17, 926 bp in length, consisting of 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs) and two ribosomal RNAs (rRNAs). The mitochondrial genome exhibits high A + T bias, accounting for 79.7% of its entirety. All PCGs start with ATN codon and end with TAN or incomplete stop codon TA or single T. The Maximum likelihood phylogenetic tree revealed a close relationship between Pachylophus and Cetema . This study contributes to the expansion of the mitochondrial genome library of Chloropinae, providing a valuable resource for gaining insights into the evolutionary history of Chloropidae., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2024 The Author(s).

Holocephali is a subclass of chondrichthyans with ample geographic distribution in marine ecosystems. Holocephalan species are organized into three families: Callorhinchidae, Chimaeridae, and Rhinochimaeridae. Despite the critical ecological and evolutionary importance, genomic information from holocephalans is still scarce, particularly from rhinochimaerids. The present study provides the first complete mitogenome of the Atlantic longnose chimaera Rhinochimaera atlantica (Holt & Byrne, 1909). The whole mitogenome was sequenced from an R. atlantica specimen, collected on the Porcupine Bank (NE Atlantic), by Illumina high-throughput sequencing. The R. atlantica mitogenome has 17,852 nucleotides with 13 protein-coding genes, 22 transfer RNA, and two ribosomal RNA genes. Nine of these genes are in the complementary strand. This mitogenome has a GC content of 41.5% and an AT content of 58.5%. The phylogenetic reconstruction provided here, using all the available complete and partial Holocephali mitogenomes, places R. atlantica in the Rhinochimaeridae family, as expected.

This study is the first to sequence the complete mitochondrial genome (mitogenome) of Perforatus perforatus Bruguière, 1789 (Balanomorpha: Balanidae). The 15,536-bp long P. perforatus mitogenome contained a typical set of animal mitochondrial genes, along with one control region. The P. perforatus mitogenome had an inverted gene block ( trnP - ND4L - ND4 - trnH - ND5 - trnF ) between trnS (gct) and trnT . This inverted gene block had been detected six species in three subfamilies of the Balanidae family (Balaninae, Acastinae and Megabalaninae), but our results show that it is also present in Concavinae, in which P. perforatus is included. The phylogenetic tree based on the concatenated sequences of the 13 protein-coding genes and two rRNA genes showed that P. perforatus is closely associated with Acasta sulcate and Balanus trigonus within Balanidae., Competing Interests: The authors report there are no competing interests to declare., (© 2024 Honam National Institute of Biological Resources.

In this study, we sequenced the complete mitochondrial genome (mitogenome) of Libelloides sibiricus , which is 15,811 bp in length, with an overall A + T content of 74.8%, encoding 2 ribosomal RNA genes, 22 transfer RNA genes, 13 protein-coding genes, and a control region. The gene arrangement and components of L. sibiricus are identical to those of most other Neuropteran species. TAA is utilized as the termination codon for most PCGs and TAG for nd1 , however, nd6 and atp6 used the incomplete termination codon TA- and cox1 , cox2 , nd5 , cytb had termination codons consisting of only T-. In addition, we selected all known 59 species of Neuroptera from NCBI, and used Sialis hamata , Sialis melania , Sialis longidens and Sialis jiyuni (Megaloptera: Sialidae) as the outgroup. Phylogenetic analysis suggested that the mitogenome of L. sibiricus was the most closely related to L. macaronius and all the owlflies formed the monophyletic group within the superfamily Myrmeleontoidea., Competing Interests: The authors report no conflicts of interest.

The species Monoserius pennarius (Linnaeus, 1758), is particularly abundant in the tropical Indo-West Pacific east of Sri Lanka, yet very limited genetic information exists for this species. Here, we report the assembled-linear mitochondrial genome of M. pennarius collected from the East China Sea. The 15,197 bp mitogenome contains 13 protein-coding genes (PCGs), two tRNA genes, and two rRNA genes. Notably, the gene order in this mitogenome differs from that of other hydrozoans within the same taxonomic order. Phylogenetic analysis, based on 13 concatenated mitochondrial PCGs, recovered M. pennarius as a sister of Nemalecium lighti (Hargitt, 1924), outside the other Leptothecata hydrozoans, suggesting paraphyly of Leptothecata. The mitogenome of M. pennarius , serving as the first publicly available for the family Aglaopheniidae, holds foreseeable value for investigating Leptothecata evolution., Competing Interests: No potential conflict of interest was reported by the authors., (© 2024 The Author(s).

The mitochondrial genome of Cybister brevis Aubé, 1838, is 16,198 bp long and includes 37 genes that are highly conserved in the family Dytiscidae. Phylogenetic analysis revealed that all genera in Dytiscidae, except Hydroporus and Oreodytes , are monophyletic. The Hydroporini tribe was found to be polyphyletic and closely associated with the Hygrotini, Bidessini, and Hyphydrini tribes. Dytiscinae was found to be a highly divergent polyphyletic group comprising three distinct clades. This study also revealed that C. brevis is closely related to Cybister japonicus and that the tribe Cybistrini diverged relatively early compared to other tribes in Hydroporinae. These findings are consistent with those of previous studies and provide new insights into the phylogeny of the Dytiscidae family, which has previously shown discrepancies between morphological characteristics and molecular data. The genome-level analyses conducted in this study serve as a valuable foundation for future investigations into the Dysticidae evolutionary history., Competing Interests: No potential conflict of interest was reported by the authors., (© 2024 The Author(s).

Vischeria punctata , as first described by Vischer in 1945, is a member of the family Chlorobotryaceae, within the order Eustigmatales. This species is recognized for its potential as a source of biofuels and other high-value products. In the present investigation, the whole genome of V. punctata was sequenced utilizing the Illumina HiSeq 4000 platform, enabling the assembly and annotation of its complete mitochondrial genome. The resulting circular genome spans 41,528 base pairs (bp) with a guanine-cytosine (GC) content of 27.3%. This genome encompasses 36 protein-coding genes, alongside 28 transfer RNA (tRNA), and three ribosomal RNA (rRNA) genes. The evolutionary trajectory of V. punctata was further explored by constructing a phylogenetic tree derived from the mitochondrial 33 gene dataset of 16 Ochrophyta species. Comparative analysis reveals that V. punctata bears closer ties to Vischeria sp. CAUP Q202 than to Vischeria stellata strain SAG 33.83, suggesting shared evolutionary pathways and phenotypic traits. This investigation constitutes the inaugural study into the mitochondrial evolution and phylogenetic patterning of the mitogenome in V. punctata .
