Status Salacia Lamouroux, 1816 and Thuiaria Fleming, 1828 have at times been regarded as congeners, although they are currently held to be distinct. A key difference in terms of morphology is the presence of an abcauline diverticulum or caecum (Millard 1975, fig. 81A) in Thuiaria and its absence in Salacia. (Calder & Faucci, 2021) [details]

Diagnosis Colonial hydroids of pinnate (branches and/or hydrocladia alternately arranged in one plane), palmate (colony has a main stem with largely ascending, long branches, converging strictly to loosely in one plane) or tree-like (branches in a loose spiral along length of stem) appearance; anastomoses rare. Hydrothecae cylindrical, slightly to distinctly outward curved, of the same diameter throughout or slightly wider basally, completely or partially immersed into stem or branch; adcauline hydrothecal wall usually almost completely adnate; abcauline wall with thickening under place of attachment of operculum. Hydrothecal rim circular (with the exception of Thuiaria gonorhiza Naumov, 1952); hydrothecal operculum composed of a single circular plate with abcauline attachment. Hydrothecae on stem arranged in opposite or subopposite pairs; number of rows of hydrothecae on stem two, falling in one plane [however, with the exception of Thuiaria arctica (Bonnevie, 1899) and Thuiaria zachsi Fenyuk, 1947!]. On the branches the arrangement of hydrothecae is also in pairs (as in the stem) or in decussate verticils of which the number of hydrothecae remains constant or is increased, three or more hydrothecae per verticil being observed, number of longitudinal rows of hydrothecae twice that number. Hydranth with abcauline caecum. Gonotheca ovoid to elongate-ovoid, inserting on stem or branches directly under a hydrotheca, usually longitudinally arranged. Gonophore a sporosac, in many species producing a marsupium outside gonotheca; certain species have curbed spiniform projection on apical part of gonotheca forming an external chamber (pseudomarsupium). Colonies dioecious; with sexual dimorphism.
