Etymology: Trachyscorpia: Greek, trachys, -eia, y = rough + Greek, skorpis, idos = a kind of fish without identification (Ref. 45335); carnomagula: The specific name carnomagula is derived from the Latin carnosus meaning fleshy, and
magulum meaning jaw or mouth, in reference to the fleshy lip on the upper jaw, compared with the poorly developed lip of T. eschmeyeri. The E.

Ecology
Marine; benthopelagic; depth range 731 - 1020 m (Ref. 58335). Temperate
Pacific Ocean: currently known only from the southwestern Pacific Ocean (Tasman Sea and northern New Zealand) at depths of 731-1020 m. One specimen (CSIRO H 2625-02, 263.3 mm SL, non-type), tentatively identified as T. carnomagula in ref. 58335 , was collected from southwest of Western Australia, Indian Ocean, at a depth of 738–750 m. Trachyscorpia carnomagula co-occurs with T. eschmeyeri.
