A new genus and two new species of deep-water bivalve-associated palaemonid shrimp (Decapoda: Caridea: Palaemonidae) from the tropical eastern Atlantic

A new genus, Meteoronia, is established for two new deep-water palaemonid shrimp species from the tropical eastern Atlantic. Both are associated with bivalve hosts and share distinctive morphological features, while differing in rostral structure and cephalic and thoracic appendages.

Collections revisited: the description of 50 new species of Terebridae

Based on material collected since 1986, this study describes 50 new terebrid species, re-evaluates four synonymised taxa, revises their taxonomic status and generic placement, and resolves long-standing classification challenges within ten genera.

Molecular Phylogenetic Reexamination of Trigonostomidae Graff, 1905 (Platyhelminthes, Rhabdocoela), with the Resurrection of Messoplana Den Hartog, 1966, and the Description of Four New Species from the United States

Using molecular and morphological analyses of ten trigonostomid species, including eight newly sequenced taxa, this study resolves relationships within Trigonostomidae, resurrects the genus Messoplana, describes four new species, reclassifies another, and refines the family's phylogenetic framework.

Discovery of new shelf and bathyal Tanaellidae Larsen & Wilson, 2002 (Crustacea: Peracarida: Tanaidacea) from Aotearoa New Zealand and the Ross Sea. I. Tanaella and allied genera

Describing five new genera and nine new species of the deep-sea tanaidacean family Tanaellidae from New Zealand and Antarctica. The study highlights their significant contribution to deep-sea biodiversity while showing the family's evolutionary relationships remain unresolved.

Greeffiella bellula n. sp. (Nematoda: Desmoscolecida): The First Desmoscolecid Nematode Species to Be Described From New Zealand

A new deep-sea nematode, Greeffiella bellula sp. nov., is described as the first desmoscolecid recorded from New Zealand waters. Phylogenetic analyses confirm its genus placement, provide a revised species key, and challenge existing relationships within Desmoscolecidae.

Lobosorchis labri n. sp. (Trematoda: Cryptogonimidae): a host switch from snappers (Lutjanidae) to wrasses (Labridae)

A new trematode, Lobosorchis labri, was discovered in wrasses at Ningaloo Reef, representing the first Lobosorchis species known from wrasses rather than snappers. Evidence suggests it evolved through a recent host switch, becoming specialised to Hemigymnus wrasses.

A review of the taxon Terebra anilis (Gastropoda, Terebridae:), with the description of two large-sized new species

A taxonomic reassessment of Terebra straminea clarifies species identities, validates two historical synonyms, describes two new large-bodied species, and supports the reinstatement of Terebra myuros as a distinct species, refining classification within the group.
