PSAMMOTHIDIUM VERNADSKYI SP. NOV. (BACILLARIOPHYTA)
FROM THE BLUE LAKE, EAST SIBERIA, RUSSIA
Bacillariophyta species composition from two lakes in East Siberia was investigated. In one
of them Psammothidium vernadskyi Bukht. et Stanislavskaya sp. nov. was found. The
diagnosis, illustrations and other necessary material for the new taxon attributes are
provided. Typification of new species and infraspecific taxa of Bacillariophyta is discussed.
K e y w o r d s : new species, morphology, taxonomy, nomenclature type, holotipe, paratype,
diatom species typification, small lakes, algal-bacterial mats.
Introduction
The algological studies of the water basins in the East Siberia mainly concern
large rivers such as Ob’ River and its tributaries (Kuksn, 1972; Safonova,
1972; Naumenko, 1995; Bogdanov et al., 2002; Semenova, 2009) and Irtysh
River (Yurova, 1974; Naumenko, 1986; Porkhacheva, 1986; Bazhenova,
2005). It is also known several publications on the diatoms (Bacillariophyta) of
these rivers (Levadnaya, Safonova, 1972; Genkal, Semenova, 1989, 1999;
Naumenko, 1995). Much less data exists on the algal flora of numerous small
ponds and streams in the East Siberia where only flood-lands and sorovye1
basins of the large rivers have been investigated so far (Popova, 1964;
Levadnaya, Safonova, 1972; Naumenko, 1986, 1988; Porkhacheva, 1986;
Belyakov et al., 2001; Stanislavskaya, 2004; Valeeva, 2009).
Recently the geoecological studies of several small lakes in the central
part of East Siberia were carried out. These lakes are located on the Tazov
peninsula within the Konda River basin — 70 km south-east of city Hanty-
Mansiysk (Kuzin, Yakovlev, 2011).
Materials and Methods
Algal composition of the algal-bacterial mats from two lakes with conven-
tional numbers N 29 and N 73 is studied (the data of Stanislavskaya in Kuzin,
Yakovlev, 2011). The algal-bacterial mats are specific communities of benthic

1Sorovye basins are mostly ephemeral flood-land basins that are arisen from spring flood.
Sorovye basins play an important role in the river basin ecosystems because they are
numerous and some of them remain for whole vegetation period and later on.

algae and bacteria habit on the littoral sand. They create somewhat friable
macrocoverings about 1-2 cm thickness olive-green or blue-green in color.
Both lakes have roundish shape with 1.0—1.5 km diameter, 2-3.5 average
depth (maximum — 5.0), under spreading bed with feldspar-quartz sands.
Because these lakes do not have any artificial sources of pollution their water
is naturally clean and colourless, has high transparency and belongs to low
salinity type of hydrocarbon-sodium waters (Kuzin, Yakovlev, 2011).
Qualitative samples of the algal-bacterial mats were collected from the
littoral sand at the depth 0.3-1.0 in the middle of July 2010. Samples were
fixed with 40 % formalin. For diatom identification they were cleaned from
an organic matter by standard cold method with concentrate sulfuric acid
(Krishtofovich, Proshkina-Lavrenko, 1949). Permanent slides were mounted
using high-refractive index resign Naphrax® (R.1. = 1.7). For scanning electron
microscopy (SEM) examination cleaned and dried diatom material from the
samples were coated with gold on 10 mm diameter stubs a JFC-1100 for 5 min.
Equipment includes light microscope Biolar PZO (Poland) with photo
camera T100 Sciencelab 10.0MPi, China; scaning electron microscope JEOL
6060LA, Japan.
Results and Discussion
Preliminary investigation showed low algal species richness in observed lakes:
11 species were found in lake N 29 and only 8 species — in lake N 73 (the
data by Stanislavskaya in Kuzin, Yakovlev, 2011). Further study of Bacillario-
phyta revealed in both lakes 37 species together with the new one for science.

D i a g n o s i s . Morphometric data: length 26—30 µm, width 10—12 µm, L/W
ratio 2.5—2.6; striae density 25—29 in 10 µm.
Frustule is slightly bent to the rapheless valve (RLV), heterovalvaty2 = 3
(valve curvature, raphe presence/absence, shape of the central hyaline areas).
Valves linear-elliptical with somewhat narrowed broadly rounded poles (Figs
1, 2, 3-6), raphe valve (RV) almost flat, RLV slightly concave and the mantles
both of them are bent under the right angle (Figs 1c, 2a). Central hyaline area
on the RV rectangle or bow-like, asymmetrically placed, almost reachs the
mantle (Figs 1c, 3-5); on the RLV — rhombic or round, asymmetrically
placed, occupies ½ of valve width (Figs 2, 2a, 6). Striae are weakly radiate
without interruption on the mantle. Areolae poroid, foramina small,
transapically oval (Figs 1a-c, 2a, 8a). Velum of hymen type has two rows of
fine round openings (Fig. 8b, arrow). Raphe system situates on diagonal, on
outside surface consists from two filiform slits that accompanied by grooves
and thin ribs (Fig. 1c), with long curved distal slits turned to the opposite
directions on the mantle (Figs 1a, 1b).

Etymology. The species is named in honor of an Academician V.I. Ver-
nadsky who elaborated the concept of the biosphere and its ecological
architecture and believed that the diatoms having siliceous cell shalls is one of
the most important component of the Earth Life.
Ecology and distribution. P. vernadskyi is only known from type locality
that characterized by naturally clean, colorless fresh water with high transparency
and belonging to the low salinity type of hydrocarbon-sodium waters. In type
locality new species amounts about 1 % within diatom community.
Observation and comparison with morphologically similar species. The thin
hymens in most areolae were destroyed, probably, for the samples treatment.
Nevertheless, a few areolae have kept velum (Fig. 8b, arrow) that consists two
rows of fine round openings.
Several species are similar with P. vernadskyi in valve outline and size
range, striae arrangement and raphe construction on the outside valve surface
that is shown in the comparable Table. More than half morphological features
coincide with well investigated Psammothidium bioretii (Germain) Bukht. et
F.E. Round and Psammothidium helveticum (Hust.) Bukht. et F.E. Round.
Psammothidium atalanta (Carter) Bukht. comb. nov. was not yet investigated

with EM therefore uncompleted data on its fine morphology does not allow to
make a proper conclusion on its similarity with new species. Psammothidium
vernadskyi distinguishes from P. helveticum (Taf. 220, Figs 1-9 in Simonsen
(1987); Fig. 20 in Bukhtiyarova and Round (1996); Fig. 8 (here Fig. 10 — 2/3
part) in Potapova (2010b) — in size and position of central hyaline area on
RLV, in position of central hyaline area on RV; diagonal raphe position; from
P. bioretii (Fig. 27 (here Fig. 9) in Bukhtiyarova, Round (1996), fig. 9 in
Potapova (2010a) on heterovalvaty is 3, flat RV, shape and size of central
hyaline areas on both valves, transapically oval areolae foramina, long raphe
distal ends curved on the mantle; from P. atalanta (Figs 15, 16 (here Figs 11,
12), 19−20 in Carter, 1966; Taf. 19, 21−24, Taf. 19, Figs 25, 25’ (here Figs
13, 14) in Lange-Bertalot, Krammer, 1989) — on heterovalvaty is 3, shape,
size and position of central hyaline areas on the both valves.
The arrangement of illustrations for our new species is based on the
principle definition of the nomenclature type that is a herbarium exemplar of
species or detailed picture of plant on the base of which new species was
described and to which species name is connected. In case of Bacillariophyta
that are microalgae and cannot be visible without microscopic equipment, the
Art. 37.5. of ICBN (McNeill et al., 2006) acts and it tells: “ … the type of a
name of a new species or infraspecific taxon of microscopic algae … may be
an effectively published illustration if there are technical difficulties of
preservation or if it is impossible to preserve a specimen that would show the
features attributed to the taxon by the author of the name” (our underlining).
Today techniques for the diatoms investigation do not allow to extract from or
keep on SEM stub single exemplar of species that served for description of
taxonomically valuable features included to the protolog. In the same time, an
effectively published microphotos have themselves a high documenting and
preservation.
For definite and fast orientation in represented illustrations we also follow
to earlier suggestion about putting of holotype microphoto together with all its
enlarged fragments on the framed table with letter T=H, that means Holotypus
(Bukhtiyarova, 2000, 2001, 2004). Because our new species has heterovalvate
frustule, RLV has different structure and view in the microscope, than chosen
as holotype RV, and is not a dublcate (or copy) of RV structure. The same
logic concerns the microphotos of LM, the inside surface fragments and TEM
microphotos. Therefore we named all those microphotos as paratypes, not as
isotypes that represent the dublcates of species from type material. Then,
species type (=holotype) here designed as framed plate, marked H, with SEM
microphotos of a single valve and its engaged fragments. Similarly, we
designed here a set of other necessary illustrations, served for species diagnose,
on framed plate marked by letters PT that means Paratypi and that those
pictures were gotten from several exemplars of type material. Thus, our chose
of holotype and paratipes for the new species Psammothidium vernadskyi is in
complete agreement both with general concept of the type and its applying for
microalgae according ICBN.

taxon by: a) heterovalvaty is 2 (valve curvature, raphe presence/absence); b)
uniform apically oval central hyaline areas on the both valves that occupy ½
of the valve width. Those features prove the status of independent species we
renew to this taxon.
Conclusions
The description of the new species Psammothidium vernadskyi within the
genus Psammothidium Bukht. et F.E. Round is based on a set of its
ultramorphological features of the genus rank according Bukhtiyarova and
Round (1996), Bukhtiyarova (2007): frustule curvature towards rapheless
valve, lenth-breadth ratio − 2,5; uniserial with uniform density striae, poroid
areolae with hymen velum and the most common for the monorafid diatoms
filiform raphe system on inside valve surface — with raphe pores at central
nodule, bent to the opposite directions (Fig. 7b), and small helictoglossa
(Fig. 7a). The new species, like the other Psammothidium species, occurs in
the fresh waters. A set of distinct ultramorphological features of species rank
clear separate Psammothidium vernadskyi from morphologically similar
P. atalanta, P. bioretii and P. helveticum.
