Distributional records of Antarctic and sub-Antarctic Ophiuroidea from samples curated at the Italian National Antarctic Museum (MNA): check-list update of the group in the Terra Nova Bay area (Ross Sea) and launch of the MNA 3D model ‘virtual gallery’

摘要

The distributional records of Ophiuroidea stored at the Italian National Antarctic Museum (MNA, Section\udof Genoa) are presented, corresponding to 1595 individuals that belong to 35 species and 17 genera.\udSpecimens were collected in 106 different sampling stations at depths ranging from 21 to 1652 m in the framework of 14 Antarctic expeditions to the Ross Sea, one to the Antarctic Peninsula, and one to the\udFalkland Islands (Islas Malvinas). Three species, Amphiura joubini Koehler, 1912, Amphiura (Amphiura)\udangularis Lyman, 1879, and Ophiura flexibilis (Koehler, 1911), are reported as new records for the Terra\udNova Bay area, whose check-list of species increases from 15 to 18 species. The determination of these\udthree new records was based both on morphological identification and molecular analyses (COI barcoding).\udSome of the genetically characterised specimens were also documented through photogrammetry\udand micro-computed tomography and represent the first bulk of 3D models that will be available through\udthe MNA and Sketchfab websites, both for research and educational purposes
