Holotype species: Dipterocladia pinnatifolia (Suhr) Y.S.D.M.de Jong
Original publication and holotype designation: De Jong, Y.S.D.M., Prud'homme van Reine, W.F. & Lokhorst, G.M. (1997). Studies on Dasyaceae II. A revision of the genera Eupogodon and Dipterocladia gen. nov. (Ceramiales, Rhodophyta). Botanica Marina 40: 421-450.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as feminine.
Most recent taxonomic treatment adopted: Schneider, C.W. & Wynne, M.J. (2007). A synoptic review of the classification of red algal genera a half a century after Kylin's "Die Gattungen der Rhodophyceen". Botanica Marina 50: 197-249.
Description: Thallus erect, sympodially developed and bilaterally branched. Indeterminate axes compressed and corticated, pinnately or irregularly producing a paired determinate lateral branch and pseudolateral from the one side of the axis, the subsequent pair on the alternate side. Determinate lateral branches polysiphonous, short, unbranched, and pyramidal. Pseudolaterals pigmented, monosiphonous throughout, 1-5 times branched, compact and tapering distally. Axial cells of indeterminate axes surrounded by 4 (-5) periaxials which are quickly enclosed by subcortical cells and exterior descending rhizoidal filaments, collectively forming a thick cortex.
Sexual plants unknown. Tetrahedral sporangia produced in successive whorls of up to 6, forming in single or paired, linear-lanceolate stichidia borne on short polysiphonous bases, these branches replacing polysiphonous determinate lateral branches. Tetrasporangia partially enclosed by corticating cover cells at maturity.
Comments: Two species with known limited distributions: Dipterocladia pinnatifolia from South Africa, D. pulchella from deep waters off Malaysia and the Marshall Is.
Numbers of names and species: There are 4 species names in the database at present, of which 4 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.
