Summary: A new species of Trichophoromyia named Trichophoromyia peixotoi is described based on morphological and molecular analyses of male specimens collected in the Parque Nacional da Amazonia, Brazil. This brings the total number of Trichophoromyia species to 45, with 24 species found in Brazil. The use of COI barcodes proved effective in species delimitation.

Summary: The study analyzed the partitioning of species groups in the butterfly subgenus Polyommatus (Agrodiaetus) using three datasets. It was found that the DNA barcoding approach alone was not able to reveal the phylogenetic structure, but the combined analysis of mitochondrial and nuclear sequences was successful in identifying species groups.

Summary: This article introduces four new resources for Western Palaearctic butterflies, including an updated species checklist, mitochondrial COI sequences, intraspecific genetic variation indexes, and species-level distribution maps. These resources will facilitate comparative studies, integrative taxonomy, and conservation strategies.

Summary: This study established the first DNA barcode database for Chinese Blepharicera by collecting specimens and using morphological characters and DNA barcoding techniques. Four new Blepharicera species from China were identified based on molecular and morphological markers. The results of this study are important for tackling taxonomic problems, understanding species distribution, and resolving nomenclature conflicts associated with Blepharicera species.

Summary: This study used partial sequences of cytochrome c oxidase subunit I to compare the genetic diversity of Red Sea populations of threadfin breams with those in the Mediterranean Sea and Indo-Pacific regions. Results showed a strong founder effect for the Lessepsian migrant N. randalli, haplotype sharing between Red Sea and Indian Ocean populations, and recommendations to avoid distributing sequences with incorrect scientific names.

Summary: This study describes new species and faunistic records of Coelosphaeridae from the Mexican Pacific Ocean. Molecular analyses suggest that Coelosphaeridae, Lissodendoryx, and Celtodoryx are not monophyletic.

Summary: Researchers developed MitoGeneExtractor, an innovative tool that extracts mitochondrial protein coding genes from next-generation sequencing datasets. It uses multiple sequence alignments to accurately and quickly extract these genes. In a case study with bird genomic datasets, MitoGeneExtractor showed higher sensitivity and faster speed compared to existing methods.

Summary: Insecta is the most diverse group in the animal kingdom, and COI gene is commonly used for species delimitation. However, high intra-specific genetic variation in insects can lead to false positives in COI-based species delimitation. The threshOpt and localMinima algorithms in the Spider package are recommended for threshold-based species delimitation studies in insects. More comprehensive research is needed on the genetic variation in COI among Insecta, and the abundant COI data in BOLD provides an opportunity for such assessment.

Summary: The taxonomy and conservation status of Majoidea superfamily in Indonesian waters were poorly documented. This study used DNA barcoding to determine the taxonomic status and evaluate the conservation status of Indonesian majoid crabs. The results indicate the need for further research on the taxonomy and conservation of Majoidea.

Summary: Overlooking cryptic species diversity has serious implications for assessing the impact of climate change on biodiversity. This study combined genetic analyses, morphological data, and geometric morphometrics to investigate cryptic species in the Rhopalomastix javana complex. The results identified five closely related species units and detected morphological differences in head shape that could be used for species diagnosis. The study also evaluated the advantages and limitations of geometric morphometrics as a taxonomic tool.

Summary: This study used DNA barcoding technology to confirm mitochondrial cytochrome oxidase I (COI) as a DNA identification standard for yellow croakers and their products in China. The results showed that 37.03% of yellow croaker products were mislabeled, indicating a widespread issue of mislabeling. COI barcode, as a molecular tool, provides an effective method for the identification of yellow croakers, preventing mislabeling of fish products and food fraud.
