In Mx1 the number of setae on the various parts are: inner lobe 1 expanded (11 or 12 fleshy setae), inner lobe 2 in stained specimen composed of 2 segments, of which the proximal bears 1 seta and the distal 2 setae; inner lobe 3 (3 setae); basal segment 2 bears 4 setae and is fringed along its inner margin with hairs; endopod fused into a single segment and bears 3, 3, 3 setae; exopod bears 10 setae; outer lobe with 10 setae.

Remarks

After Pearson (1906, p.20): vertical range down to 700 m at 53°58'N, 12°28'W. For the author this species may prove to be the same as Xanthocalanus muticus Sars, 1905. Sampling depth (Antarct., sub-Antarct.) : 0-2000 m. Sargasso Sea: 1000-1500 m (Deevey & Brooks, 1977, station "S");
This species is maintained in the genus Xanthocalanus by certain authors, admitting however the genus Talacalanus.
According to Tanaka & Omori (1967, p.247) Wilson's record from the surface off Peru is incredible, also the occurrence of the species from NW Pacific adjacent to Japan is the first record from the Pacific.
