Description
Table 1. Differences between species of the genus Cymbopleura.
| Outline | Ends | Axial area | Central area | Valve length (μm) | Valve width (μm) | Striae in 10 μm | Areolae in 10 μm | Distribution | Reference | |
|---|---|---|---|---|---|---|---|---|---|---|
| C. natellia sp. nov. | subelliptical, dorsiventral with moderately convex dorsal margin and slightly convex ventral margin, which more often almost straight near the valve centre | bluntly rostrate, not protracted | narrow, more often weakly expands to central area, less often - almost not expands, almost the median line of the valve | more or less pronounced, rounded, 1/3 the valve breadth | 17.6-23.5 | 8.7-9.5 | 13-15 at the central part, 18-20 near the ends | 30-35 | Russia: Baikal Lake | This study |
| C. naviculiformis | elliptic-lanceolate, moderately dorsiventral, dorsal margin strongly arched, ventral margin slightly convex to nearly flat | rostrate to subcapitate, narrow-protracted | narrow, linear or slightly broader towards the relatively large central area, almost in the median line of the valve | rounded, one-half to two-thirds valve width | 26-50 | 9.0-13.0 | 10-15 at the central part, 16-19 near the ends | 27-35 | Widely distributed | Krammer 2003; Bahls 2019 |
| C. designata | broadly lanceolate, moderately dorsiventral with strongly arched dorsal and ventral margins | apiculate, extending laterally from valve ends | area about 1/4th to 1/5th valve width, slightly curved and narrower near apices | rounded, scarcely wider than the axial area | 26-37 | 9.0-11.6 | 12-14 at the central part, up to 18 near the ends | 26-30 | Sub-Arctic and Arctic | Lange-Bertalot and Genkal 1999; Bahls 2019 |
| C. frequens | not or very slightly dorsiventral, subelliptical-lanceolate, dorsal an ventral margins moderately arched | protracted, apiculate to rostrate | narrow, linear, narrowing slightly towards to the ends, almost median line of the valve | irregular, asymmetric space of different extent | 14-38 | 6-9 | 11-14 at the central part, 16 near the ends | 30-36 | Holarctic | Krammer 2003; Kulikovskiy et al. 2016; Bahls 2019 |
| C. hercynica | slightly dorsiventral, broadly subelliptical to elliptical-lanceolate, dorsal margins strongly, ventral margin slightly arched | apiculate to subrostrate protracted | very narrow, almost the median line of the valve | 1/3-1/2 the valve breadth, distinctly set off, rounded, sometimes asymmetrical and then more well-developed dorsally | 16-40 | 7-10 | 12-15 at the central part, up to 20 near the ends | 32-36 | Holarctic, saline habitats or with higher electrolyte content | Krammer 2003; Li et al. 2007 |
