All three smaller specimens were missing the telson and most pereopods. Even though the specimens were in too bad condition to be identified further or potentially be described, some characteristics are worth noting. In agreement to Dahl’s (1959) note of a damaged Rhachotropis specimen from the Kermadec Trench, 7140–7180 m, which is also missing the urosome, the present species also has a small, downward pointing rostrum and a first coxal plate which is “not at all produced anteriorly”. Dahl (1959) noted “In the maxilliped the outer plate reaches well past the first segment of the palp, and the ... : Published as part of Lörz, Anne-Nina, 2010, Deep-sea Rhachotropis (Crustacea: Amphipoda: Eusiridae) from New Zealand and the Ross Sea with key to the Pacific, Indian Ocean and Antarctic species, pp. 22-48 in Zootaxa 2482 on pages 45-46, DOI: 10.5281/zenodo.195450 ...
