Holotype species: Khawkinea hallii T.L.Jahn & W.R.McKibben

Original publication and holotype designation: Jahn, T.L. & McKibben, W.R. (1937). A colorless euglenoid flagellate, Khawkinea halli n. gen., n. sp. Transactions of the American Microscopical Society 56(1): 48-54.

Precise date of publicationJanuary 1937

Most recent taxonomic treatment adopted: Cavalier-Smith, T. (2016). Higher classification and phylogeny of Euglenozoa. European Journal of Protistology 56: 250–276, 2 figs.

Description: Colorless cells that would be placed in the genus Astasia except for possession of an eyespot and flagellar swelling (presumed photoreceptor), indicating derivation from the green genus Euglena by loss of chloroplasts. Freshwater or parasitic in freshwater flatworms, copepods and annelids; widespread.

Numbers of names and species: There are 63 species names in the database at present, as well as 1 infraspecific names. Of the species names, 15 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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