Morphological description.

The frustule has the form of a drum, valves are almost flat, diameter 24.4-26.6 μm, 8-10 marginal processes in 10 μm, 2-5 central processes (Fig. 4E View Figure 4 ).

Ecology.

Conticribra weissflogii is a planktonic diatom, from marine and brackish-water environments that also may occur in lacustric and riverine waters. It is reported to occur in a wide range of salinity 2-26‰ (representing oligohalobs to polyhalobs), especially at salinities above 5‰ ( Stachura-Suchoples and Kulikovskiy 2014). This taxon tends to increase in population density with rising temperature ( Lomas and Glibert 1999) as well as with eutrophication ( Zheng et al. 2016). It is also known to grow in waters with relatively high pH, around 8-9.4 ( Sala 1997).

Distribution.

This centric taxon appeared at the Mykolaiv site in the Southern Bug River; for Ukraine it was mentioned for the first time in our previous investigation (Table 1 View Table 1 ; Genkal and Bilous 2015), afterwards it was found in the tributaries of Dnipro in eastern and central parts of the country ( Berezovskaya 2019; Kryvosheia and Kapustin 2019).

This is a widely distributed species: Europe, Asia, America (North and South), Africa, Australia and New Zealand; it was even found in Lake Baikal, also in the oceans over the world ( Stachura-Suchoples and Kulikovskiy 2014; Genkal et al. 2020).
