Unverified
Taxonomic remark The original description by P.J.L. Dangeard, 1965 was invalid (genus described after after 1 January 1958 with no type species designated). This attempt to validate it by R.L. Guillard et al. in 1975 (with type H. saccatum) was also invalid since the proposed type species was not validly described in that work (no holotype designated), refer Guiry, 2017. The genus was subsequently validated by Guiry, 2017, with a different type species, H. marinum P.J.L. Dangeard ex M.D. Guiry, 2017. [details]
