Article Reference An ichthyological borderland: The fishfauna of Nyungwe National Park and surroundings (Rwanda, East Africa)
Nyungwe National Park (NP) is a mountainous region situated in the southwestern part of Rwanda on Congo-Nile watershed. In spite of the high biodiversity in pri- mates, birds and plants, no fish were reported to occur in the park, probably because of the cold temperatures of the rivers. An expedition in 2022 examined the fish diver- sity within the Nyungwe NP and its buffer zones. Additional sampling was performed in the main river draining the park into Lake Kivu: the Kamiranzovu. Three hundred and twenty specimens belonging to 13 species were collected. Specimens were col- lected only in the western part of the park, draining towards the Congo basin. The diversity within the park proper was limited to two putative species within the com- plex of Amphilius cf. kivuensis, which were caught on either side of the Kivu–Rusizi watershed. In contrast, a higher fish diversity, including one clariid species and two species of Enteromius, was observed in the rivers at a lower altitude of the buffer zone. However, the highest species diversity was found near the mouth of Kamiran- zovu River, including 11 species, of which 4 were non-native: the guppy Poecilia reti- culata, Astatotilapia burtoni, the blue-spotted tilapia Oreochromis leucosticus and the Egyptian mouth-brooder Pseudocrenilabrus multicolor.

Article Reference ANNiKEY Linear – diagnoses, descriptions, and a single-access identification key to Annelida family-level taxa
Phylum Annelida are ubiquitous metazoans found in almost every terrestrial and aquatic habitat on Earth. Historically, taxonomic studies on the phylum have been focused largely on its majorgroups, polychaetes, oligochaetes and leeches, so that while family-level keys for each group are available, no single-source identification guide exists to the world’s annelid families. Here, the first illustrated linear key to annelid families is provided and family-level descriptions and diagnoses that distinguish individuals of each family from those of other families in the phylum are updated. This information is generated from an annelid DELTA database of 334 characters and 166 mostly family-level taxa. A link is provided to downloadable software (ANNiKEY Interactive) allowing the same data to be interrogated using the open-source DELTA program Intkey, which enables both interactive identification and taxonomic query functionality. For each family-level taxon, a diagnosis, full description, links to taxonomic data at the World Register of Marine Species, illustrations of diagnostic features, and a summary of the recent literature, including a list of published keys to genera and species are provided.

Article Reference Penaeus aztecus Ives, 1891 (Crustacea, Decapoda), in the Scheldt estuary (Belgium): Isolated record or forerunner of a penaeid invasion?
A single specimen of the penaeid prawn Penaeus aztecus (Ives, 1891) was recorded in 2018 in the brackish zone of the Scheldt estuary near Antwerp (Belgium). The presence of this species, native to the West Atlantic, might result either from ships' ballast water coming from transatlantic boat shipping, from illegal import or from a considerable expansion leap northwards from the Mediterranean Sea, where this species has recently established and now has rapidly expanding invasive populations.

Article Reference Integrative taxonomy of giant crested Eusirus in the Southern Ocean, including the description of a new species (Crustacea: Amphipoda: Eusiridae)
Among Antarctic amphipods of the genus Eusirus, a highly distinctive clade of giant species is characterized by a dorsal, blade-shaped tooth on pereionites 5–7 and pleonites 1–3. This lineage, herein named ‘crested Eusirus’, includes two potential species complexes, the Eusirus perdentatus and Eusirus giganteus complexes, in addition to the more distinctive Eusirus propeperdentatus. Molecular phylogenies and statistical parsimony networks (COI, CytB and ITS2)of crested Eusirus are herein reconstructed. This study aims to formally revise species diversity within crested Eusirus by applying several species delimitation methods (Bayesian implementation of the Poisson tree processes model, general mixed Yule coalescent, multi-rate Poisson tree processes and automatic barcode gap discovery) on the resulting phylogenies. In addition, results from the DNA-based methods are benchmarked against a detailed morphological analysis of all available specimens of the E. perdentatus complex. Our results indicate that species diversity of crested Eusirus is underestimated. Overall, DNA-based methods suggest that the E. perdentatus complex is composed of three putative species and that the E. giganteus complex includes four or five putative species. The morphological analysis of available specimens from the E. perdentatus complex corroborates molecular results by identifying two differentiable species, the genuine E. perdentatus and a new species, herein described as Eusirus pontomedon sp. nov. ADDITIONAL KEYWORDS: alpha taxonomy – cryptic species – genetics – molecular systematics – phylogenetic systematics.
