Summary: DNA barcoding and metabarcoding are widely used for species discovery and biodiversity assessments, but high error rates can inflate estimates. The debar package utilizes a hidden Markov model to denoise COI sequences, reducing indel errors and being sensitive to true COI variation in the animal kingdom. This results in more accurate sequences and aids in characterizing species diversity.

Summary: Studies on fish eggs and larvae have been conducted since the late 19th century and have provided important information for understanding fish fauna and environmental inventory. The use of molecular identification techniques, particularly DNA barcoding, has greatly improved taxonomic precision in studying ichthyoplankton. Recent research shows a significant increase in the use of DNA barcoding, with high accuracy compared to traditional taxonomic identification methods.

Summary: Parasitoid wasps are recognized as a highly abundant and diverse group of organisms on Earth, with a crucial role in regulating populations of Lepidoptera, Coleoptera, and Diptera. However, there is still limited knowledge regarding the biology and taxonomy of many parasitoid species. This study describes a new species of Pseudophanerotoma and its host, the tortricid moth Cryptaspasma perseana, providing detailed taxonomic and barcoding information.

Summary: Arthropods are crucial organisms in terrestrial systems, but little is known about highly abundant and megadiverse groups, especially in the tropics. Our study analyzed arthropod communities using DNA barcoding techniques and found more than 10,000 distinct groups, with a drastic undersampling of the sampling sites. We also discovered significantly distinct communities, despite the close proximity of the two Malaise traps.

Summary: Two new species of aphids were described, Aphis (Toxoptera) fafuensis and Aphis (Toxoptera) sennae, which feed on Adinandra millettii and Senna bicapsularis, respectively, in China. Morphological and molecular data supported the taxonomic classification of these new species within the subgenus Aphis (Toxoptera). A key for identifying apterous viviparous females of this subgenus was provided.

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 study identified 11 independent genetic lineages of Ralfsia-like taxa, leading to the proposal of a new classification unit, Pseudoralfsiaceae, and two new genera, Pseudoralfsia and Nuchella. Additionally, species of Pseudoralfsiaceae can be distinguished from Ralfsia sensu stricto (Ralfsiaceae) mainly by DNA sequences and by consistently having frequent hair pits, and typically unsymmetrical thalli.

Summary: Specimens of Spyridia 'filamentosa' from Southern New England and New York were sequenced for mitochondrial COI-5P and chloroplastic rbcL genes, showing distinct differences from Mediterranean specimens. As a result, a little-known species name, Spyridia americana Durant, was assigned to specimens collected from the northeastern coast of the United States.

Summary: In the last decade, molecular tools have revealed previously unrecognized taxa in Bermuda's marine flora, especially among the Rhodophyta. Misidentified species have been reclassified and many novel species have been discovered. The `Laurencia complex' has also been modified globally, with five of the eight recognized genera found in Bermuda. The study presents new species and revises the classification of existing ones using genetic sequencing.

Summary: By screening DNA from 285 coralline crusts in Canada and adjacent waters, the distribution range of Porphyra corallicola was found to be far beyond previous knowledge. In addition, it was found that other species also exist only in the Conchocelis stage. The further development of this method will facilitate the study of Conchocelis stages in nature, greatly enhancing ecological knowledge of bangialean species.

Summary: The Acrotylaceae, a red-algal family composed of six genera, lacks common habits and vegetative features among them, with cystocarps being the most unifying characteristic. Molecular studies reveal that the family consists of two subfamilies, Acrotylaceae and the newly proposed Clavicloniaceae. The South African genus Reinboldia, previously included in Acrotylaceae, is now considered questionable for inclusion in the family.
