Summary: Our study focuses on the Dendrobium orchids, which have large morphological divergence and difficulties in species taxonomy. We assembled the complete mitogenomes of two Dendrobium species and compared them with other orchids. The results reveal extensive variations in repetitive and chloroplast-derived sequences in Dendrobium mitogenomes, and the intergenic content has undergone expansion during evolution. We also sequenced the mitogenomes of 26 Dendrobium species and reconstructed their phylogenetic relationships based on mitochondrial and plastid data. The mitochondrial phylogeny shows partial characteristics of the plastid phylogeny and provides new insights into the phylogenetic relationships of Dendrobium species.

Summary: This study reports the complete mitochondrial genome sequences of 12 Chironomus species and one Microchironomus species for the first time. The analysis of these mitogenomes, combined with previously reported ones, provides insights into the nucleotide composition, codon usage, selection pressure, and heterogeneity of Chironomus species. The phylogenetic relationships of Chironomus based on these mitogenomes were also reconstructed. The findings demonstrate the conservative nature of Chironomus mitogenomes in terms of nucleotide composition and gene order, enriching the existing knowledge of chironomid mitochondrial genomes and contributing to a better understanding of the evolutionary history of Chironomus.

Summary: The recently reorganized classification of Mantodea has made progress in resolving homoplasy problems, although some relationships among higher taxa remain uncertain. In this study, newly sequenced mitogenomes and nuclear gene sequences were used to compare the structure of mantodean mitogenomes and perform phylogenomic studies. The results reveal conserved mitogenome organizations with some gene rearrangements. The phylogenetic analysis shows compositional heterogeneity and lineage-specific evolutionary rates among mantodean mitogenomes, and the use of a heterogeneous mixture model produces better-fit topologies. The results confirm the monophyly of several superfamilial groups and provide insights into the phylogeny of Mantodea.

Summary: In this study, the mitogenomes of five Thienemanniella species were sequenced and analyzed, revealing their conserved structure and ancestral gene order. Significant variation in nucleotide composition was observed among different genes, with the control region exhibiting the highest A + T content. All protein coding genes showed evidence of purification selection, with ATP8 being the fastest evolving gene. Phylogenetic analyses supported five topologies for Thienemanniella.

Summary: Chalcididae is a moderate-sized family within the superfamily Chalcidoidea in Hymenoptera, with 1548 species worldwide. Phylogenetic analysis based on mitogenomes supports the basal position and monophyly of Chalcididae within Chalcidoidea. The newly sequenced mitochondrial genomes of two Chalcididae species show similarities in structure and feature, providing insights into the evolutionary relationships among families in the Chalcidoidea superfamily.

Summary: Typhlocybinae, the smallest and most evolved leafhopper family, consists of over 6000 species distributed worldwide. By sequencing and comparing 11 complete mitogenomes, it was found that the gene number and order are highly conserved in these organisms, with the PCGs showing a consistent start and end codon pattern. Phylogenetic analyses confirmed the monophyly of Typhlocybinae and its inner tribes, except for Typhlocybini and Zyginellini, which were found to be paraphyletic.

Summary: Dactylispa, a large genus of leaf-mining beetles with 387 species, feeds on the largest number of host plants among leaf-mining hispines. The current morphological classification of Dactylispa is problematic, but the first molecular phylogenetic trees constructed using mitochondrial genomes partially resolved the evolutionary relationships. Further studies with more species are needed to explore the evolutionary issues within this genus.

Summary: This study presented the complete mitochondrial genomes of four Chironomid species and conducted a comparative analysis of mitochondrial genomes among six subfamilies within Chironomidae. The results showed that the mitochondrial genomes of Chironomidae are conserved and displayed poor signals in phylogenetic reconstructions at the subfamily level.

Summary: The family Mycetophilidae consists of more than 4,500 described species with some economically important to cultivated mushrooms and crops. Through mitochondrial genome sequencing and phylogenetic analysis, it was found that the superfamily Sciaroidea is monophyletic, and the phylogenetic relationships within Mycetophilidae were recovered as (Manotinae + Sciophilinae) + (Mycomyinae + Mycetophilinae). Gene rearrangements were frequent in the crown group, suggesting rapid evolutionary rates in Sciaridae and Cecidomyiidae, which may explain their high species diversity.
