Holotype species: Mantoniella squamata (Manton & Parke) Desikachary

Original publication and holotype designation: Desikachary, T.V. (1972). Notes on Volvocales - I. Current Science (Bangalore) 41: 445-447.

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Throndsen, J. (1996). The planktonic marine flagellates. In: Identifying marine phytoplankton. (Tomas, C.R. Eds), pp. 591-730. San Diego: Academic Press.

Description: Unicellular flagellates with two flagella, but one flagellum is so short as to appear knob-like in the light microscope. The long flagellum is directed posteriorly during swimming. The cell contains a single parietal crescentic chloroplast with a pyrenoid. Stigma located on the pyrenoid surface. The cell also contains ejectile organelles, probably mucilage containing (mucocysts). Cells covered with several types of submicroscopic unmineralized scales. Flagellar scales of two types, hair-shaped scales in two nearly opposite rows inserted between longitudinal rows of spineless spiderweb scales. Two additional types of spiderweb scales cover the cell body. Sexual reproduction unknown.

Comments: The type species is distributed world-wide in marine and brackish environments, while the second species, M. antarctica, is known only from the Antarctic. It differs in structure of the scaly covering. Studies on ultrastructure and mitosis by Barlow and Cattolico (1980, 1981), Marchant and others (1989) and Moestrup (1990). Mantoniella and its allies in the Mamiellaceae are considered to be some of the most primitive green plants.

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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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