Summary: Ligusticopsis litangensis, a new cryptic species from Sichuan Province, China, has distinct morphological boundaries compared to Ligusticopsis capillacea and Ligusticopsis dielsiana, with distinguishing features such as long conical multi-branched roots and oblong-globose fruits. By comparing the plastomes of L. litangensis with 11 other species of the genus Ligusticopsis, it was confirmed that L. litangensis represents a new species within the genus. The highly conserved plastid genomes among the 12 Ligusticopsis species further support the classification of L. litangensis as a new species.

Summary: Marine protists have traditionally been considered low in diversity and widespread, but recent studies have shown the presence of cryptic species complexes. Overcoming sampling and methodological limitations, global metabarcoding data analysis reveals geographic and ecological differentiation driving speciation among marine protists.

Summary: In this study, molecular phylogenetics was used to investigate the potential cryptic speciation in foliicolous members of Strigula s.lat. in tropical areas of Asia. The study identified several new species and revealed a high degree of diversification in this group of lichenized fungi, indicating that the current understanding of their diversity is likely incomplete.

Summary: The genus Bois Hubner comprises 254 species, with 217 described from the Neotropics and 31 having their type locality in Brazil. The actual diversity of Eois is greatly underestimated and the Brazilian fauna is poorly known due to inadequate sampling and the potential existence of cryptic species.

Summary: Through investigations in national reserves and Vietnam parks, it was discovered that the Cordyceps militaris complex, including two hidden species, attacks lepidopteran pupae or larvae. Phylogenetic analysis and morphological comparisons confirmed the descriptions of two new taxa and one known species in the complex. Furthermore, the morphological characteristics of 11 species within the C. militaris complex were compared.

Summary: Marine rockpools are unique habitats characterized by harsh conditions for life, but some specialized invertebrates, such as certain water beetle species, have successfully colonized these environments. Recent molecular studies have shown the presence of multiple potentially new species within the subgenus Cobalius, indicating a need for taxonomy revision. Phylogenetic analysis revealed the possible origin of Cobalius in the Early Miocene and the diversification of most species during the Late Miocene, Pliocene, and Pleistocene.

Summary: In this study, the taxonomy and phylogeny of colonial Dinobryon species were investigated using molecular and morphological methods. The results revealed 15 different genetic lineages based on the nuclear ITS sequences. Phylogenetic analysis of the combined multigene dataset identified 18 subclades, including five new species. Morphological studies focused on lorica dimension and shape, as well as stomatocyst morphology. Based on these findings, five new species were proposed.

Summary: The use of genetic methods has allowed the discovery of previously undistinguishable species based on morphology. However, these cryptic species are rarely considered in ecotoxicology, which can lead to false extrapolations and lack of reproducibility in experiments. It is crucial to address the ecological differentiation and sensitivity of closely related cryptic species for evolutionary ecology, conservation biology, and regulatory ecotoxicology.

Summary: The study shows that morphological identification of Aspergillus spp. is accurate at the species level in over 95% of cases, but there is low concordance in cases with low detection rates. Cryptic species exist within the A. fumigatus and A. niger complexes, showing higher resistance to antifungal drugs.

Summary: Sampling in multiple localities and molecular barcoding reveal the presence of local cryptic species in allopatry in wide-ranging nominal species. However, cryptic species in sympatry can easily be missed if they have different seasonality and require long-term frequent sampling for identification. This study investigates the presence of cryptic species within a temporal gradient and on a spatial scale in Hydrozoa using mitochondrial sequencing and finds a high number of sympatric cryptic species. The bi-dimensional cryptic diversity highlighted in this study is crucial for understanding evolution processes, biogeography, and biodiversity assessments in the sea.

Summary: This study analyzed the microbial ecology of Southern California marine fishes and identified body site as the strongest driver of microbial diversity. The gill of larger, pelagic fishes had the lowest microbial biomass and diversity. Phylosymbiosis patterns were observed across different body sites. In addition, the study showed that mammals have the highest gamma diversity in vertebrate hindguts, while fishes have the highest percentage of unique microbial taxa.

Summary: RNA sequencing and phylogenomic analysis were used to reconstruct the evolutionary relationships within the phylum Onychophora, revealing a well-supported phylogeny for the family Peripatopsidae with signals of Gondwanan vicariance. However, the family Peripatidae in the Neotropical region showed unstable relationships largely due to amino acid-translated sequence data. Discordant phylogenetic signal between genes may indicate a rapid, mid-Cretaceous radiation in the group.

Summary: Donacidae is a commercially important family of heterodont bivalves that has successfully colonised brackish and fresh waters. Using molecular data and fossil records, we propose an evolutionary hypothesis for this widely distributed group. Our analysis supports the monophyly of Donacidae and reveals the paraphyly of Donax. The diversification of Donacidae is closely linked to the opening of the Atlantic Oceans and the closing of the Tethys Ocean.

Summary: Petallidae is a family of mite harvestmen that inhabit former circum-Antarctic Gondwanan terranes. A new pettalid species, Archaeopurcellia eureka, from South Australia, has been discovered, filling the distributional gap of Australian pettalids. Phylogenetic analyses reveal that the new genus is related to the Chilean Chileogovea, possibly due to the Antarctic land bridge between these two terranes.

Summary: Munidopsid squat lobsters are abundant decapods in the East Pacific and new species, as well as new distribution records, have been described. Phylogenetic analysis revealed the nesting of Janetogalathea californiensis within Munidopsidae and the reassessment of Phylladiorhynchus and Coralliogalathea's taxonomy. The study also suggests a wider geographic range for abyssal species than previously thought.

Summary: We present the first annotated draft genome for the phylum of Onychophora, a group of cryptic, soil dwelling worms. The genome's large size is due to high repeat content, intron size inflation, and extensive gene family expansion. We also report a previously unknown diversity of onychophoran hemocyanins, suggesting independent diversification of copper-mediated oxygen carriers in Onychophora after its split from Arthropoda and parallel diversification of hemocyanins in each of the main arthropod lineages.

Summary: Genomic data for priapulans are limited, so this study generated a high-quality priapulan genome for Tubiluchus corallicola using a combination of sequencing technologies. The assembled genome had a high level of completeness and was screened for homologs of key genes involved in the molting pathway. The presence of a putative homolog suggests a deeper origin for these genes in Ecdysozoa.

Summary: This study describes new Cyphophthalmi specimens from Burmese amber, including fossils representing an ongoing transition in some lineages during the late Cretaceous. The discovery of unique morphological novelties in Cyphophthalmi fossils, such as elongated ozophores and numerous pits covering the body, provides insights into their evolutionary history. The diversity of Cyphophthalmi during the Cretaceous is further supported by the identification of additional specimens with unique adenostyles. The total number of named Burmese amber Cyphophthalmi species is increased from one to six, expanding our knowledge of this suborder's fossil record.

Summary: Onychophora, or velvet worms, are important for understanding the evolution of Ecdysozoans. The Peripatidae family presents taxonomic issues, especially in the Neotropical region. Research on Neopatida has shown that relying solely on morphological characters is insufficient to resolve phylogenetic relationships at higher taxa, while analyses of molecular or combined data indicate that Neotropical species can be divided into two clades.
