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 Bordnamonas tropicana Larsen et Patterson 1990 ( Figs 1e , 2f ) Observation: Cells are 7 to 12 μm long and slightly flattened. The cells are anteriorly narrow and posteriorly broad. Two slightly thickened flagella are similar in length, insert subapically in the right ventral side of the cell and are about the cell length. The flagella are not acronematic. The anterior flagellum beats stiffly in a sigmoid arc and the posterior flagellum curves near its flagellar insertion and is directed posteriorly. The cells glide or skid rapidly close to the substrate. Description based on observations of three cells. Remarks: Bordnamonas tropicana has been reported from marine sites worldwide with cell lengths of 4–20 µm ( Larsen and Patterson 1990 ; Vørs 1992a , b; Patterson et al. 1993 ; Ekebom et al. 1996 ; Patterson and Simpson 1996 ; Lee and Patterson 1998 , 2000; Lee 2001 , 2002; Al-Qassab et al. 2002 ). Cell appearance is entirely consistent with the descriptions of Larsen and Patterson (1990) and Lee and Patterson (2000) . This species resembles Bodo curvifilus Griessmann 1913 in that the anterior flagellum is held anteriorly in a curve, but can be easily distinguished by the swimming pattern, the thickness of the flagella and the anterior mouth visible by light microscope. This species is also distinguished from other bodonids by the swimming pattern and the thickness of the flagella.
