Type locality. Canada, British Columbia: Fairway Channel, N of Gabriola Island ( Fraser 1914a). 

Current status. Invalid.

Remarks. Fraser (1914a) described Thuiaria distans  without designating a type. Nevertheless, a hydroid colony from the type locality in the Fraser Hydroid Collection at the RBCMAbout RBCM ( BCPMAbout BCPM 976-00708-001), listed above, is certain to be a type specimen. Given that Fraser was not explicit in stating the number of colonies in hand as the species was being described, however, we avoid assuming that the specimen is the holotype by monotypy and designate it as the lectotype ( ICZN Recommendation 73F). The printed catalogue of the Fraser Collection indicates that the specimen was dry at some point but was rehydrated in January 1984. For all that, it is still in fair condition. Other specimens of the species occur in the Fraser Hydroid Collection at the RBCMAbout RBCM ( BCPMAbout BCPM 976-00709-001: Northwest Bay, 19 June 1914; BCPMAbout BCPM 976-00709-002 and BCPMAbout BCPM 976-00709-003: Northwest Bay; BCPMAbout BCPM 976- 00710-001: 14 km S of Marble Island, 26 June 1935, 347 m), but they are not part of the type series.

Thuiaria distans Fraser, 1914a  is an invalid junior primary homonym of Thuiaria distans Allman, 1877  . Fraser (1918a) discovered the homonymy and proposed Thuiaria geniculata  as a nomen novum for it. However, that replacement name has been widely if not universally overlooked, even by Fraser (1937a, 1947a) himself. Unaware of the correction in nomenclature, Calder (1991) replaced the original name of Fraser’s species with another, Salacia fraseri  . The two nomena nova are objective synonyms, with T. geniculata Fraser, 1918a  having priority. Held to be valid by Cairns et al. (2002) as Thuiaria fraseri  , and in WoRMS as Salacia fraseri  , the species is assigned here to Thuiaria Fleming, 1828  under the binomen T. geniculata Fraser, 1918a  .

Originally described from the trophosome only, gonothecae of T. geniculata  were described and illustrated later by Fraser (1937a, as T. distans  ).
