Two new species of Liljeborgia Spence Bate, 1863 (Crustacea, Amphipoda, Liljeborgiidae) from the Clarion-Clipperton Zone, Pacific Ocean
Two new species of Liljeborgia are described from the Clarion-Clipperton Zone, central-east Pacific Ocean. Liljeborgia scylla sp. nov. is described from a single immature male specimen collected at 4223 m depth. This species is characterised by a tooth-like protrusion on the second gnathopod, a very narrow basis of pereopods 5–7, and a shallow cleft in the telson. Liljeborgia sibylline sp. nov. was collected at depths ranging from 4107 to 4287 m and is described from six specimens. Despite similarities in morphology to Liljeborgia scylla sp. nov., Liljeborgia sibylline sp. nov. can be distinguished by characters of the gnathopods, telson, and epimeron 3. Molecular barcode data are also provided for both species, offering additional insights into their genetic distinctiveness.
