Etymology: Holohalaelurus: holos (Gr.), whole or entire, i.e., being a form of Halaeurus without any labial folds or grooves in the mouth (See ETYFish); punctatus: Latin for spotted, referring to dense covering of small brown spots on dorsal surface (See ETYFish).

Western Indian Ocean: endemic to the subtropical and tropical waters of southwestern Indian Ocean, southern Mozambique, off Natal, South Africa and off Madagascar (Ref. 75585).
Status of threat: a common catch in bottom trawls in Natal and southern Mozambique, yet, despite recent biodiversity trawl surveys in that region, not a single specimen has been collected from this area since 1972. ORI data sheets confirm that specimens collected between 1964 and 1972 were apparently abundant, particularly off Mozambique in May 1969, and off Durban in June 1971. The only specimens of this species that have been collected since this date have been those from Madagascar in the late 1980’s and early 1990’s (Ref. 75585).
