Taxonomic status: This name is currently regarded as a synonym of Melobesia.

Comments: Chamberlain (1983: 300) concluded from an examination of the type specimen (L 941.241-152) that Hapalidium roseolum, the type species of Hapalidium, is a heterotypic synonym of Melobesia membranacea (Esper) J.V. Lamouroux, the type species of Melobesia (Family Hapalidiaceae). Consequently, Hapalidium Kützing (1843) is treated as a heterotypic synonym of Melobesia J.V. Lamouroux (1812).

Even though Hapalidium is a heterotypic synonym of Melobesia, the family name Hapalidiaceae, which is derived from the generic name Hapalidium, is legitimate and therefore nomenclaturally correct, as explained by Woelkerling (1988: 86) and Harvey et. al. (2003: 995).

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
