Abstract Red-blooded neritimorph gastropods in the subfamily Shinkailepadinae are specialists of chemosynthesis-based ecosystems, with most diverse genus Shinkailepas endemic to deep-sea hydrothermal vents. All described species have so far been from western Pacific, despite reports unidentified Indian Ocean literature for decades. Here, we use an integrative approach characterize and describe these vent neritimorphs first time, based on material collected Carlsberg Ridge (CR) Central (CIR). We name two new species: tiarasimia sp. nov. both CR CIR, cornuthauma CR. A combination shell epipodial lobe characters reliably separate their congeners. phylogenetic reconstruction all known using 658 bp mitochondrial COI gene reveal major clades within genus, each species—implying independent colonizations vents by lineages. Our finding CR, including one not anywhere else, underscores unique biodiversity at strengthens case protecting them potential mining activities.

Integrative taxonomy provides a valuable approach to discover and unravel even morphologically almost indiscernible species, such as those forming “cryptic” species complexes. The six members of the recently discovered Haploniscus belyaevi complex (short: -complex) from abysso-hadal Kuril-Kamchatka Trench (KKT) region in Northwest Pacific Ocean are taxonomically described herein. eponymous is redescribed alongside new descriptions five closely related apaticus sp. nov. , H. erebus hades kerberos nyx morphological differences between these most eminent rostral pleotelson morphology adult males. Alongside light-microscopical drawings, CLSM scans, 16S COI barcodes, complemented by first genomic data deep-sea haploniscid isopods. Geometric morphometrics was applied quantify interspecific intraspecific considering pronounced sexual dimorphism. distributional range -complex covers large geographical area, ranging across greater KKT extending beyond large-scale geomorphological barriers Kuril Island Ridge, turning into promising study differentiation processes deep sea.

The Mediterranean Sea is recognized as one of the most threatened marine environments due to pollution, unintentional spread invasive species, and habitat destruction. Understanding biodiversity patterns within this sea crucial for effective resource management conservation planning. During a research cruise aimed at assessing near desalination plants in vicinity Larnaca, Cyprus, conducted part WATER-MINING project (Horizon 2020), specimens tanaidacean genus Apseudopsis were collected. These classified into two identified new science, are described herein larnacensis sp. nov salinus nov. distinguished from its congeners by presence lateral apophysis on pleonite 5, which longer than those pleonites 1–4, hyposphenia pereonites 2–6, six ventral spines propodus pereopod 1. characterized rounded posterolateral margin pereonite 6, 1–6, four An updated key Atlantic species provided.

Confusion between the means and ends, specifically technological achievements their users, has been evident in taxonomy’s history since end of last century. Following a current thought implicit Anglo-Saxon culture, this trend aligns with idea inevitability. It is inevitable, so it thought, that what human organism can do, machine will be able to do at some point time. This ultimately lead dispensing element for things they not wish themselves.
