Description: Deep-water scalpelliform with reduced armament. Notable that the cirri are black – in other deep forms they have no pigmentation.
This is a more "yellow" species. Trianguloscalpellum hirsutum is described as being a pale yellow to brown color whilst, although undescribed in the literature, in general Trianguloscalpellum regium specimens are whitish grey in color. The Indo-Malayan distribution of T. hirsutum, however, indicates that to date it has only been recorded from the eastern Indian Ocean, but since there has been little deep water sampling in the Indian Ocean in general, it would not be surprising to find it in western areas. The recorded depth range of Trianguloscalpellum hirsutum is 1507-6135 m, which fits with the 2,500 m collection depth and, therefore, this is possibly Trianguloscalpellum hirsutum as the "yellow" species.
