Free-living Heterotrophic Flagellates from Intertidal Sediments of Saros Bay, Aegean Sea (Turkey) Author Aydin, Esra Elif Author Lee, Won Je text Acta Protozoologica 2012 51 2 119 137 https://www.mendeley.com/catalogue/6cf3745c-7fc3-3086-8e0b-e266c329ac0d/ journal article 10.4467/16890027AP.12.010.0514 1689-0027 13192960 Goniomonas amphinema Larsen et Patterson 1990 ( Figs 1l , 2k ) Observations: Cells are 5–5.5 μm long, oblong and laterally flattened. Two flagella insert in an anterior lateral pocket; one directed anteriorly, one posteriorly. The cells have three delicate longitudinal ridges on both sides, which can be easily overlooked. The anterior row of ejectisomes is sometimes difficult to observe. Description based on the observations of two cells. Remarks: The genus Goniomonas contains three species, G. amphinema , G. pacifica and G. truncatum . Goniomonas amphinema differs from G. pacifica and G. truncatum in having dissimilar flagella one of which curves to lie along the ventral side of the cell. This species was reported from marine sites in Australia , North Atlantic, Denmark , England , Fiji , Gulf of Finland , Panama and Korea and was reported to be 4 to 9 μm ( Vørs 1992a , b; Larsen and Pattersen 1990; Patterson et al. 1993 ; Tong et al. 1998 ; Lee and Patterson 2000 ; Lee 2001 , 2002, 2006b; Al-Qassab et al. 2002 ).
