Current status. Valid.

Remarks. Fraser (1941b) designated material at the NMNHAbout NMNH ( USNMAbout USNM 22922) as the “ type ” of Halecium dubium  . Although currently listed in the online database of that museum as a syntype, the specimen count is correctly indicated as “1”. Moreover, Fraser’s (1941b: 83, 84) original description of the species reveals that it was based on a single male colony, stating “…the specimen from which this species is described…” The single NMNHAbout NMNH specimen is therefore the holotype ( ICZN Art. 73.1.2).

Fraser (1941b) considered Halecium dubium  to be much like H. telescopicum Allman, 1888  from Australia (off Port Jackson). He distinguished it as new because it lacked repeated reduplication of the hydrophores. Also considered unusual by him was the existence of a small semicircular notch at the distal end of the male gonotheca. Halecium dubium  is recognized as a valid species in WoRMS.
