Chaetoceros pseudocurvisetus Mangin (Chaetocerotales, Chaetocerotaceae).
Arctic, Barents Sea, near shore of Island Severny of Novaya Zemlya Archipelago (77°22.9'-77°59.0rN, 64°46.3'-65°53.1'E), phytoplankton, 1-29 m, 16 VIII 2016, Evdoki-mov, Pankova (Евдокимов, Панъкова), B-06poverkhnost, B-10 picnoclin.
Cells in short colonies, 21-22 ^m in diam., 31-42 ^m high. Cell density 11-23 thousands cells per m3 (8-14% of algal number), biomass — 0.15-0.3 mg per m3 (3-12% of algal biomass), water temperature 3.7-4.2 °С, salinity 31.1-32.3 %o. Diatom Chaetoceros socialis Lauder and dinoflagellate Ceratium arcticum (Ehrenb.) Cleve were dominated with this species in phytoplankton assemblage.
Chaetoceros pseudocurvisetus is a rare boreal-tropical marine species. It is known for Russia1 from the Sea of Japan (Gogorev et al., 2006), for Europe — from Ireland, North, Adriatic and Mediterranean seas (Guiry, Guiry, 2017).
1 Record ofthe species in the Black Sea is given in AlgaeBase (Guiry, Guiry, 2017), but the link to the electronic resource «BSPC Editorial Board 2014» (Black Sea Phytoplankton Checklist, http://phyto.bss.ibss.org.ua/Main_Page) is invalid.

New chrysophytes records from Russia. S. N. Shadrina, T. V. Safronova. — Новые находки золотистых водорослей для России. С. Н. Шадрина, Т. В. Сафронова.
Paraphysomonas eiffelii H. A.Thomsen = Clathro-monas eiffelii (H. A.Thomsen) J. M. Scoble et Cavalier-Smith.
This species was twice found (31 V 2013 and 29 VIII 2017) in the water channel of Lugovoy park (Petergof, Petrodvortsovy District of St. Petersburg; 59°52'11.0"N, 29°54'02.6"E). The water parameters were measured on 31 V 2013 as follows: t = 23 °C, pH 7.5, specific conductivity 530 ^S ст-1, Safronova, water sample not preserved; and 29 VIII 2017: t = 16.5 °C; pH 7.5, specific conductivity of 453 ^S сш"1, Shadrina Ball_30.1_2017, algae collection of Komarov Botanical Institute.
Loose tower scales of this species were found (Plate I). Tower scales are 2.7 ^m long and with large-meshed funnel-shaped base 1.1 ^m in diam. Their projections up to 2 ^m long and terminate in a distinctly bifurcate tips 0.22-0.23 ^m long.
The species is widespread (Kristiansen, 2000). It is known from Austria (Pichrtova et al, 2013), Denmark (Thomsen et al, 1981), England (Preisig, Hibberd, 1982; Finlay, Clarke, 1999; Esteban et al, 2012), northern Germany (Hickel, Maaß, 1989), Hungary (Barreto, 2005), Chile (Dürrschmidt, 1982), Canada (Nicholls, 1984), Madagaskar (Hansen, 1996), China (Wei, Yuan, 2015) and South Korea (Kim, Kim, 2011). In all localities it is rare species and lives in freshwater reservoirs, swamps and also under ice. P. eiffelii has been reported in a wide range of conditions: pH varied from 6.2 (Barreto, 2005) to 8.7 (Wei, Yuan, 2015), conductivity from 102 ^S сш-1 (Pichrtova et al, 2013) to 890 ^S сш-1 (Preisig, Hibberd, 1982) and temperature of water from 0 °C (Thomsen et al, 1981) to 30 °C (Hansen, 1996).
