Ultrastructure of Amastigomonas bermudensis ATCC 50234 sp. nov.

Heterotrophic flagellates and other protists associated with oceanic detritus throughout the water column in the mid North Atlantic

“…Molina & Nerad, 1991). The organisms described correspond more closely with the slim form and have a profile similar to that of A. bermudensis (Molina & Nerad, 1991). They are not identified as A. bermudensis because they are about half its size.…”

“…Amastigomonas de Saedeleer, 1931 This genus of gliding biflagellate protists has recently been reviewed by Molina & Nerad (1991). Cells have a dorsal organic flexible theca covering the cell and the base of the anterior flagellum, the posterior flagellum trails under the cell.…”

Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia

“…® losa and A. mutabilis. This species can be distinguished from A. bermudensis Molina and Nerad, 1991 by its smaller size (A. bermudensis, 8± 11.5 mm), and from A. mutabilis by its smaller size (A. mutabilis measures up to 15 mm) and the lack of granules located ventrally adjacent to the posterior¯agellum. It is distinguished from A.…”

“…This species was ® rst described as Rhynchomona s mutabilis by Griessmann (1913 ), transferred to Thecamonas by Larsen and Patterson (1990) and to Amastigomonas by Molina and Nerad ( 1991). Previously reported length ranges are 7± 15mm.…”

Early evolution of eukaryote feeding modes, cell structural diversity, and classification of the protozoan phyla Loukozoa, Sulcozoa, and Choanozoa

“…This only occurred drastically when rigifilids lost both cilia, and to a smaller degree when Glissodiscea became more discoid and flattened, thus changing their cell shape more radically (see below), and after Diphyllatea stopped gliding, deepened their groove and became a novel type of swimming zooflagellate. Apusomonads are conservative also in their ciliary transition zone, which is short and simple with a simple distal transverse plate to which the central pair of microtubules is attached (Karpov 2007;Karpov and Mylnikov 1989;Molina and Nerad 1991) as in Malawimonas and other Loukozoa (O'Kelly and Nerad 1999). By contrast the base of the central pair in Planomonadida and Diphyllatea is ensheathed by a medium to high density sleeve of structure unique in protists Brugerolle 2006;Heiss et al 2011).…”
