Holotype species: Hapalidium roseolum Kützing
Currently accepted name for the type species: Melobesia membranacea (Esper) J.V.Lamouroux
Original publication and holotype designation: Kützing, F.T. (1843). Phycologia generalis oder Anatomie, Physiologie und Systemkunde der Tange. Mit 80 farbig gedruckten Tafeln, gezeichnet und gravirt vom Verfasser. pp. [part 1]: [i]-xxxii, -142, [part 2:] 143-458, 1, err.], pls 1-80. Leipzig: F.A. Brockhaus.
Precise date of publication: 14-16 September 1843 (see Stafleu & Cowan 1979: 686 for details). The requirements for valid publication are specified in the ICBN (International Code of Botanical Nomenclature).
Taxonomic status: currently regarded as a synonym of Melobesia.
The ICBN rules cited below are those adopted by the Seventeenth International Botanical Congress, Vienna, Austria, July 2005 (McNeill et al. 2006).
In accordance with ICBN Art. 13.3, the name Hapalidium is treated as pertaining to a non-fossil taxon because its type is based on a non-fossil specimen. No species based on fossil types have been assigned to the genus.
The generic name Hapalidium is typified (ICBN Art 10.1) by the type of H. roseolum, the only species originally included in the genus. - (28 Aug 2009) -
Description: No genus description is provided currently as this names is treated as a synonym.

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).
Numbers of names and species: There are 9 species names in the database at present.
Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
