Currently, the subfamily Meconematinae encompasses 1029 species, but whole-mitochondrial-genome assemblies have only been made available for 13. In this study, the whole mitochondrial genomes (mitogenomes) of nine additional species in the subfamily Meconematinae were sequenced. The size ranged from 15,627 bp to 17,461 bp, indicating double-stranded circular structures. The length of the control region was the main cause of the difference in mitochondrial genome length among the nine species. All the mitogenomes including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs) and a control region (CR). The majority strand encoded 23 genes, and the minority strand encoded 14 genes. A phylogenetic analysis reaffirmed the monophyletic status of each subfamily, but the monophysitism of , and was not supported.

Although there is a consensus on the distinctiveness of Saginae, its phylogenetic position within Tettigoniidae remains a topic to debate. Comprehensive DNA data are essential for clarifying subfamilial relationships within the Tettigoniidae. This study investigates the complete mitogenome of Saga natoliae, providing critical insights into the phylogenetic position of the Saginae.

Katydids were surveyed in the Iguau National Park (ParNa Iguau), the largest preserve of the Interior Atlantic Forest in Brazil. Sampling was carried out in three different areas of the ParNa Iguau, including its two predominant phytophysiognomies (Seasonal Semidecidual Forest and Mixed Ombrophilous Forest), and consisted of diurnal and nocturnal active searching for katydids and also using light traps. After collected, specimens were reared until adulthood in order to record their calling songs.

This paper provides the first description of a female of Shoveliteratura triangula Shi, Bian Change, 2011, as well as the complete mitogenome sequence using next-generation sequencing (NGS) technology. The length of the entire mitogenome was 16,152 bp and contained the typical gene arrangement, base composition, and codon usage found in other related species. The overall base composition exhibited a clear anti-G (10.

Katydids from the subfamily Meconematinae sing at ultrasonic frequencies. Owing that many of them are nocturnal, elusive and low in abundance (since they are predatory), there is a dearth of information on these katydids and their bioacoustics, especially for species in the understudied yet mega-diverse Southeast Asia. Recent orthopteran surveys in Laguna, Luzon Island in the Philippines led to the discovery of two interesting Meconematinae katydids.
