Description: Free-swimming, biflagellate monads, obovoid or fusiform and slightly compressed; a longitudinal furrow extends from the sub-apical vestibulum almost to the posterior of the cell and is lined with four or more conspicuous rows of ejectisomes, gullet absent; a single chloroplast pyrenoid and nucleomorph, the chloroplast containing the phycobiliprotein Cr-phycoerythrin 545, and is brown fading to yellow-brown in older cells; the periplast with an inner component sheet and a superficial component of rosulate scales sandwiching the plasma membrane. Repreduction occurs by simple cell division in the motile state; palmelloid colonies apparently not formed; cysts and sexual reproduction unknown. The ultrastructure has been examined. The nucleomorph is located in the periplastidial compartment anterior to the pyrenoid; thylakoids do not traverse the pyrenoidal matrix. The thylakoids in T. acuta are arranged in three's rather than the usual loosely associated pairs in other cryptomonads. Teleaulax acuta possesses an unusual type of Cr-phycoerythrin 545. Although Teleaulax is common and often abundant in marine coastal habitats worldwide, it has rarely been recorded in the literature, probably due to it being overlooked because of the delicate nature of the cells and the difficulty in bringing it successfully into unialgal culture. The genus has been recorded in European, Japanese and Australian waters

Numbers of names and species: There are 5 species names in the database at present, of which 5 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
