A new species of Pardalisca Krøyer, 1842 (Crustacea, Amphipoda, Pardaliscidae) from the Clarion-Clipperton Zone in the abyssal central east Pacific

The Pardaliscidae is one of the most abundant and species-rich families of Amphipoda in the deep sea. Among pardaliscid species collected from abyssal depths (4185– 4182 m) of the Clarion-Clipperton Zone as part of the MANGAN 2023 cruise, a single large representative of the genus Pardalisca was recovered. The species was confirmed as new to science and is here illustrated and described in detail; a confocal laser scanning microscope (CLSM) image and a molecular barcode are also provided.

Pardalisca magdalenae sp. nov. differs from its congeners by the shape of the dorsal process on urosomite 1 as well as the morphology of the gnathopod dactyls.
