Nota: The length of the outer subdistal spine on P4 endop-3 was slightly smaller than the outer distal spine in the Red Sea specimens, whereas in specimens from the Gulf of Naples both spines are equal in length (Giesbrecht;, 1892, Pl.47, Fig.59). Thes differences, however, can be regarded as variation between specimens (as found for instance also in T. dentipes.

After Wi & al. (2011, p.603) T. umerus and T. denticulata co-occurred south of Cheju Island, where the Kuroshio Current provides the main inflow into the East China Sea and Sea of Japan via the Tsushima Warm Current and Cheju Warm Current. According to Hsieh and Chiu (2002) and Hsieh & al. (2004) T. minuta, like T. similis should be indicators of an intrusion of the Kuroshio Current in the East China Sea.
Esterly (1905, p.217) suggests that the male, figured by Aurivillius (1899, p.29, figs.1-3) could belong to this species, what could not be confirmed by Böttger-Schnack (1999).
For Böttger-Schnack (1999, p.78) many records of this species in the world ocean are cited, but are doubtful, because they did not include figures or a description that positively identified the species.
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 5 corresponding to small sac-spawning detritivorous.
