摘要:
A new species of amphipod crustacean (Amphipoda: Phtisicidae), Paraproto mccaini n. sp. is described based on specimens collected from south of Elephant Island, the South Shetland Islands near the Antarctic Peninsula. This species was first reported as Paraproto condylata (Haswell, 1885) [sensu lato], recorded from a temperate region of Australia. P. mccaini n. sp. is distinct from P. condylata [sensu stricto] by an elongated head with pereonite 1, presence of a mid-lateral projection on pereonites 2-4, and lack of a distal round projection on the propodus of gnathopod 2. Paraproto differs from Pseudoprotomima, the most phylogenetically similar genus, in having gills on pereonites 3 and 4. (C) 2015 Elsevier B.V. and NIPR. All rights reserved.
