Summary: A new species of terrestrial isopod, Lucasioides altaicus sp. nov., is described from the Altai Mountains in southwestern Siberia, representing the first record of Lucasioides in Russia and the northernmost habitat of terrestrial isopods known in Eurasia. The study includes diagnostic characters of the new species and a preliminary phylogenetic analysis within the family Agnaridae.

Summary: Accurate identification of deep-sea species is challenging due to insufficient and inadequate identification keys. This study tested various techniques, including morphological and molecular approaches, for the identification of deep-sea isopods. Interactive identification keys based on the DELTA format were found to be reliable in identifying species within the Haploniscidae family, and even enabled the identification of a new species. However, these keys have limitations when dealing with species with ontogenetic or sexual dimorphism.

Summary: A new marine Sargassum-boring species of Limnoria, Limnoria aspera sp. nov., was discovered in Kamogawa-shi, Chiba Prefecture, Japan. It shares some characteristics with other species but differs morphologically, and has a genetic distance of 14.2-18.0% from other Japanese species based on COI sequences.

Summary: This article describes the identification of parasitic copepod species from the genus Lernaeopoda found in Argentina using morphological and molecular analysis. The study reveals that the identified species belong to Lernaeopoda bivia and proposes a misidentification of L. galei. The article emphasizes the importance of using an integrative approach for revising the taxonomy of Lernaeopoda species worldwide.

Summary: This study conducted morphological and molecular analysis on two species of cymothoids collected from Okinawa Island, Japan. It revealed the distribution and morphological characteristics of these species, and identified a new northern range limit for Cymothoa indica. It also found a close relationship between the two nominal species of Mothocya, indicating the need for further research.

Summary: This study described Probopyrus populations from different regions of the Amazon basin based on sequences of two genes, revealing two Probopyrus species parasitizing coastal or inland populations of M. amazonicum. The findings suggest the potential use of COI barcode for identifying Probopyrus species.

Summary: Eight species (including four new) of Urocleidoides found in Characiformes and Gymnotiformes fishes in the Eastern Amazon are reported in this study. The phylogenetic analysis based on molecular data reveals the relationship between Urocleidoides species and the absence of vaginal sclerite. The study also addresses the relationships between Urocleidoides and other Neotropical dactylogyrids.

Summary: Two new Caucasian species of the genus Niphargus belonging to the southwestern Caucasian Niphargus borutzkyi ingroup were discovered in underground habitats in Western Georgia. They are morphologically and genetically distinct from other known species, particularly in uropod III and epimeral plates. The study provides an identification key for the Niphargus borutzkyi ingroup and discusses their phylogenetic relationships, estimated time of origin, and current distribution in the Colchis lowland of the southwestern Caucasus.

Summary: This study investigated the distribution patterns of boring sponges and pea crabs on oyster reefs in Georgia, revealing their varying impacts on oyster condition across different intertidal zones. The findings highlight the importance of understanding biotic stressors on oyster reefs for effective management and restoration efforts, particularly in the southeastern USA.

Summary: Adult isopods of the family Dajidae are ectoparasitic and infect pelagic malacostracan crustaceans, with planktonic copepods as intermediate hosts. This study provides a taxonomic review and updated diagnosis of the genus Holophryxus, including traditional and novel morphological characters. The presence of previously ignored sensory structures is highlighted. A new species, Holophryxus citriformis, is described, and the importance of enhanced descriptive standards in future research is emphasized. Additionally, host records and geographical distributions of all Holophryxus species are summarized.

Summary: This study redescribes Mothocya parvostis based on type and additional materials collected from the host. Morphological and genetic data confirm that M. sajori and M. parvostis are the same species. The study also conducted morphological and molecular analyses on isopods collected from Japan, finding consistent results with the type specimens.

Summary: DNA barcoding has become a popular method for species identification. A study as part of the German Barcode of Life project has presented the first DNA barcode library for terrestrial and freshwater isopods from Germany. The study found high intraspecific genetic distances and variability, but still succeeded in accurately assigning species based on interspecific distances.

Summary: A questionnaire survey in Europe found that leishmaniases are not universally notifiable in countries with autochthonous cases. Few countries have surveillance and control measures in place for both animal and human infections. Lack of resources is a major challenge for controlling leishmaniases, which are considered emergent diseases in most countries.
