![]() ![]() Granoreticulose – Naked amoeboid organisms with branched filopodia over which numerous granules move extremely quickly in both directions and which can form an extensive network (reticulum).Pseudopodia usually appressed to the substratum. Granules are evenly distributed and move slowly or not at all. Granofilose – Naked amoeboid organisms with granular filose pseudopodia. Diagnosis: The test is ovoid or elongated elliptic, slightly yellowish or brownish, laterally compressed with small lateral pores (number of pores can vary).Filose – Naked amoeboid organisms with filamentous pseudopodia.Some species have subpseudopodia, small extensions of a hyaline anterior zone. Lobose – Naked amoebae with finger-shaped, tubular pseudopodia.the Nebela tincta ism and local distribution is detected for different complex), it also contains mainly, and perhaps habitat types such as closed basin lakes, peat- mostly. contains some problematic which size the threshold between cosmopolitan- species that require revision (e.g. Granuloreticulose – Testate amoeboid organisms with branched filopodia over which numerous grains move extremely quickly in both directions and which can form an extensive network (reticulum). Phryganella acropodia Hertwig and Lesser, 1874, is one of the most common and abundant testate amoeba species. It would thus be interesting to compare at the genus Nebela s.l. Nebela is a diverse genus of testate amoebae of cosmopolitan distribution, belonging to the family Hyalospheniidae.Test and pseudopodia appressed to the substratum. Twenty-six taxa, including the three most abundant in the dataset (i.e. Granofilose – Testate amoeboids with granular filose pseudopodia. ![]() Filose – Testate amoebae with filose (filamentous) pseudopodia.Lobose – Testate amoebae with finger-shaped, tubular pseudopodia.the size and the shape of the aperture might be a taxonomical character.the main taxonomic morphological characters are the size and the shape of the shells.the number and presence of pores has no taxonomical value.the type and overall composition of the test cannot be used as a taxonomic character.Other clades aremade up of monophyleticNebelaspecies including clade I (99 BS/1.00 PP), clade III (71 BS/0.84 PP),clade IV (BS/0.99PP) and clade V (79 BS/0.68 PP). tincta(KP691349 andKP691350) may be non-monophyletic as they are unresolved in this reconstruction. rotunda and described three new species, N. Additionally, Nebela speciosa(JN849045) and two N. They showed that small variations in test morphology, often overlooked by traditionally taxonomy, correspond to distinct haplotypes and they redefined Nebela tincta, N. (2012) examined the relationship between morphological and genetic diversity within the species complex of Nebela tincta-collaris-bohemica. Further studies are needed to clarify the variability in size within this taxon. These dimensions were given by Kosakyan et al. The neck is very short with a linear aperture and surrounded by an organic collar.ĭimensions: Length: 90-95 µm, breadth: 62-71 µm, L/B ratio: 1.3-1.4. The test is generally composed mainly of oval or circular test plates but can also be composed mainly or only of organic cement. ![]()
