Thes differences, however, can be regarded as variation between specimens (as found for instance also in T. dentipes.

Remarques

méso-bathypélagique.
Esterly (1905, p.217) suggère que le mâle figuré par Aurivillius (1899, p.29, figs.1-3) pourrait appartenir à cette espèce, ce qui ne peut être confirmé par Böttger-Schnack (1999).
Pour Böttger-Schnack (1999, p.78) la signalisation de cette espèce dans les divers océans est sujet à caution, faute de figures ou de descriptions suffisantes pour certifier son identification.
