Summary: DNA sequence analysis is crucial for species delimitation in Diaporthe, but combining multiple genes without genealogical concordance criteria complicates species delimitation. Using GCPSR and PTPs methods, the D. eres complex was identified as a single species, contrary to the current recognition of multiple species. Absence of reproductive isolation and low genetic diversity indices suggest D. eres constitutes a population rather than distinct lineages.

Summary: A study of well-preserved discodorid nudibranchs collected in Koumac, New Caledonia, discovered seven new species belonging to the genera Atagema, Jorunna, Rostanga, and Sclerodoris. However, the generic assignments are tentative due to an unresolved phylogeny of Discodoridi-dae. The paper emphasizes the significance of comprehensive collecting efforts in identifying and documenting well-camouflaged taxa.

Summary: This study used phylogenomics and genetic diversity patterns to infer the colonization sequence and timing of mainland common chaffinches to Macaronesia, and assessed whether colonization of different archipelagos led to a species-level radiation. Results revealed a rapid radiation of common chaffinches across Macaronesia, driven by sequential colonization of different archipelagos, resulting in genetically distinct, independent evolutionary lineages.

Summary: This study focused on the classification, phylogeny, and species identification of Liphistius spiders. By analyzing sequences from 162 specimens collected in Thailand and Myanmar, the relationships among Liphistius species and species groups were determined, confirming the accuracy of morphology-based classifications. The study also revealed the origin of Liphistius species in the Sibumasu region and their speciation in their current distribution areas.

Summary: Species delimitation is crucial for understanding the mechanisms behind biodiversity. Traditional alpha taxonomy relied on expert knowledge to describe new species, while DNA-based methods like the multispecies coalescent model (MSC) offer a more objective approach, though recent criticisms question their accuracy in certain situations.

Summary: By combining multi-locus DNA sequence data and morphological characteristics, new species within the Cystolepiota genus have been identified, leading to the resurrection of the Pulverolepiota genus. It was also discovered that C. seminuda is a species complex, consisting of at least three species. The study provides a comprehensive understanding of the phylogeny and taxonomy within this group of fungi.

Summary: Phylogenomic investigations aid in detecting genetic structure and demographic histories, but identifying species-level differentiation remains challenging. Reference-based taxonomy establishes a framework for species delimitation, helping to recognize two species within the Greater Short-horned Lizard complex. Paraphyly of P. hernandesi is supported, with evidence of three populations lacking reproductive isolation, highlighting difficulties in implementing a reference-based approach.

Summary: Species identification is essential for ecological, phylogeographic, and evolutionary studies, but conducting taxonomic studies in the molecular era can be challenging. This study focuses on common, difficult-to-distinguish European species within the genus Polycera to address the broader issues of cryptic species and their impact on biodiversity research. By analyzing a large dataset encompassing morphological and molecular data, the study identifies four species within a complex, highlighting the importance of accurate taxonomic analysis. The study reveals the presence of both cryptic and non-cryptic components within the same species, suggesting the need for a more comprehensive understanding of organismal diversity.

Summary: This study aimed to delimit species boundaries within the Rhododendron species complex, resulting in the identification of two distinct species and one putative hybrid group. The findings were based on morphological analyses and population genetic data, indicating a potential introgression event that formed the hybrid group. Further investigations are needed to validate the existence and characteristics of this hybrid group.

Summary: This paper examines three species (informally referred to as species A, B, and C) of the Baileyi Complex within the Anopheles subgenus Anopheles. Species A is identified as An. baileyi, while species B and C are newly described and named as An. monticola and An. bhutanensis, respectively. The study provides a comparison of the morphological characteristics of the adults, male genitalia, larvae, pupae, and chaetotaxy of the immature stages of these species with An. baileyi from Bhutan. It reveals significant differences in the structures of the male genitalia and larval setae development among the three species.

Summary: This study compared the diversity, coverage, and biomass of beached seaweeds on the north-eastern and south-eastern coasts of Brazil. The results showed that while the north-eastern coast had higher species richness, the south-eastern coast exhibited higher coverage and biomass. The frequency and distribution of beached seaweeds varied significantly across beaches in Brazil, providing insights into their biodiversity and biomass and their potential economic use in the future.

Summary: This study used morphometric analysis to determine the existence of characters that distinguish five species of the Gracilaria mammillaris complex in the Mexican Atlantic. The results showed that only Gracilaria curtissiae differs significantly from the other species in the complex. The study suggests that an ongoing speciation process may be responsible for the lack of distinguishable morphological traits in most of the studied species.

Summary: The present study adds 19 species to the marine macroalgal flora in the Azores, increasing the total number of species in this region to 521. Some of the newly found species fall within their known distributional range, while others represent an extension to their distribution in the Atlantic. Several of the species are likely introductions to the Azores, and the status of one species is uncertain. The discovery of six new species in intertidal algal turf samples highlights the importance of further research in this area.

Summary: The diatom Minutocellus polymorphus is a widely studied species that is an ideal model for toxicity tests due to its rapid growth. Although its gross morphology has been extensively described, the ultrastructural characters associated with its importance are unknown. Through a collection made in Acapulco Bay, Guerrero, Mexico, cells morphologically identical to M. polymorphus were isolated, and a first description of the genus' ultrastructure was provided through cultures and observations in a transmission electron microscope. Further detailed studies are needed to increase knowledge about the ultrastructure of diatoms on the Mexican Pacific coasts where they are previously unknown.
