Remarks. Błażewicz-Paszkowycz et al. (2011) gave a partial description of a sphyrapid species with mixed characters of Pseudosphyrapus (i.e., conspicuous rostrum, articulation of pereonite 1 with the cephalothorax, parallel-sided pleon with small lateral spine-like apophyses, and short proximal article in the antennular mainflagellum) and Sphyrapus (i.e., no accessory flagellum on the antennule) but refused to name a new species due to the scarcity and poor quality of the available material. According to the characters in the description, it is undoubtedly a novel taxon, and thus it is included here. Additional material would be required to formally establish its taxonomy.
Ecology. This species was found in Kidd and Jesus Baraza MVs, in sediments composed by carbonate clay and mud breccia, at 552 and 1105 m depth.
