Taxonomic remark There is some disagreement in the generic placement of this species. From Lowry & Kilgallen, 2014:

"D’Udekem d’Acoz & Havermans (2012) include A. plebs and A. rossi in the tryphosine genus Pseudorchomene Schellenberg, 1926 based on molecular evidence. Abyssorchomene plebs and A. rossi are morphologically dissimilar to P. coatsi (Chilton, 1912), the type species of Pseudorchomene, Schellenberg, 1926, but very similar to species usually assigned to Abyssorchomene. D’Udekem d’Acoz & Havermans (2012) did not test the molecular affinities of the other ten species of Abyssorchomene against Pseudorchomene before moving these species. Transferring A. rossi and A. plebs to Pseudorchomene confounds the morphological concept of both genera. Therefore based on the maxilla 1 setal-tooth arrangement and the morphology of the first gnathopods we prefer to retain these species within Abyssorchomene until such time as affinities of the entire Abyssorchomene/Pseudorchomene complex have been tested." [details]
