Cairaeanthus gen. n. (Cestoda, Rhinebothriidea),
with the Description of Two New Species from Dasyatis pastinaca
in the Black Sea and the Sea of Azov. Kornyushin V. V., Polyakova
T. A. — Two new species were identified among cestodes
collected from Dasyatis pastinaca (Linnaeus, 1758) in the Black
Sea and the Sea of Azov. Their morphology corresponds in the most
characters to the descriptions of Phyllobothrium lactuca van Beneden,
1850 and P. gracilis Wedl, 1855 by L. Borcea (Borcea, 1934) and
T. P. Pogorel’tseva (Pogorel’tseva, 1960) from the same host and
seas. However, some morphological characters of these cestodes
(namely, the marginal loculi on the pedicellate bothridia, cephalic
peduncle, absence of the apical sucker and post-poral testes,
genital pore opening marginally, close to posterior end of proglottid)
correspond to diagnosis of Rhinebothriidea. Since the species
from the Black Sea and the Sea of Azov did not fit diagnoses of
any known genera currently belonging to Rhinebothriidea, the new
genus, Cairaeanthus Kornyushin et Polyakova, gen. n., with two
species, C. ruhnkei Kornyushin et Polyakova, sp. n. and C. healyae
Kornyushin et Polyakova, sp. n., is established. Cairaeanthus
gen. n. differs from Anthocephalum Linton, 1890 in absence of
apical sucker, posteriorly bifid bothridia and vitelline fields
interrupted by the ovary, not extending in the posterior end of
the proglottid. The new genus can be distinguished from Rhinebothrium
Linton, 1890, Echeneibothium van Beneden, 1850, Rhabdotobothrium
Euzet, 1953, Rhinebothroides Mayes, Brooks et Thorson, 1981, Scalithrium
Ball, Neifar et Euzet, 2003 by the absence of facial loculi on
the bothridia and by numerous vitelline follicles, stopping at
the anterior margin of the ovary; from Rhodobothrium Linton, 1889
— by absence of post-poral testes, and from Spongiobothrium Linton,
1889 — by numerous vitelline follicles, stopping at the level
of ovary. C. ruhnkei sp. n. differs from C. healyae sp. n. in
the lengths of the strobila, the cephalic peduncle and the bothridia
pedicel, in size of marginal loculi and the ovary, in the number
of the proglottids and the testes in the proglottid, and in the
structure of genital atrium. Two new species are differentiated
also from the morphologically related species Phyllobothrium pastinacae
Mokhtar-Mocamouri, Zamali, 1981. Examined type specimens of P.
pastinacae were attributed to Rhinebothiidea based on a set of
morphological characters. However, they appear to differ from
all known Rhinebothriidea, including the species from the genera
Anthocephalum Linton, 1890 and Cairaeanthus gen. n. Taxonomic
position of P.pastinacae needs further identification.
Key words: Cairaeanthus gen. n., Rhinebothriidea, Cairaeanthus
ruhnkei sp. n., Cairaeanthus healyae sp. n., Phyllobothrium pastinacae,
Dasyatis pastinaca, the Mediterranean Sea, the Black Sea, the
Sea of Azov.

Species Composition and
Zoogeographic Peculiarities of Mysid Shrimps (Crustacea, Mysida,
Mysidae) of Utlyuk and Molochny Lagoons (Northern Azov Area).
Vasilkovskaya O. B. — Results of studies of faunas, distribution
and ecology of the mysid shrimps (Mysidae) in 1992–2010 in different
areas of Utluk and Molochny Lagoons are provided. Four species
of mysids, Diamysis pengoi (Czerniavsky, 1882), Paramysis ullskyi
(Czerniavsky, 1882), P. lacustris (Czerniavsky, 1882), P. intermedia
(Czerniavsky, 1882) are recorded for the first time from the north-western
part of Molochny Lagoon. The family Mysidae is represented by
14 species and subspecies of 7 genera, of them, by 14 species
in Utluk Lagoon, and 11 species in Molochny Lagoon. Based on the
analysis of their ecological preserences , the mysids of this
region are considered to be marine. The mysids in this area are
shown to belong in 5 zoogegraphic complexes, depending on their
preferences of water salinity. Similarities in the structure of
Utluk and Molochny Lagoon faunas are discussed. Comparative analysis
of the faunas dynamics in the last 20 years is given.
Key words: Mysida, Crustacea, fauna, ecology, zoogeography, Utluk
Lagoon, Molochny Lagoon, Ukraine.

N. V., Martynov V. V., Martynov A. V. — Based on long-term
studies (2002–2009) the modern species composition of the land
mollusks of Donetsk and Azov uplands and some adjacent territories
in Eastern Ukraine is analysed. The largest species diversity
is registered in the flood plain forests and the small forests
in steppe ravines. The influence of the land mollusk fauna of
the Caucasus and Crimea in the species composition of the land
mollusks of Donetsk upland and adjacent territories is analysed.
Published works devoted to land mollusks of the studied region
are briefly reviewed.

Deep-Water Benthic Polychaetes
(Vigtorniella zaikai and Protodrilus sp.) in the Black Sea as
Indicators of the Hydrogen Sulfide Zone Boundary. Zaika V. E.,
Sergeeva N. G. — The Black Sea hypoxic layer, situated
near the boundary of the hydrogen sulfide zone, is inhabited by
the polychaetes Vigtorniella zaikai, Kisseleva, 1992 and Protodrilus
sp., which can serve as indicators of the interface between oxic
and anoxic water. The maximum number of polychaetes in the northern
part of the Black Sea occur at a depth of 150 m, while near Bosporus,
where the flow of the Marmara Sea water enters the Black Sea,
the peak depth varies from 150 to 250 m.
Key words: Black Sea, hypoxia, Polychaeta, biological indicators
of hydrogen sulfide, abundance, distribution.

Phenotypic Variability
and Taxonomical Status of the Species of the Genus Philipomyia
(Diptera, Tabanidae). Andreeva R. V. — Range of variability
of morphological characters is studied for the species of the
genus Philipomyia Olsufjev, 1964, which have wide ecological plasticity
as representatives of the mountain landscape complex. Diversity
of combinations of several vari-able morphological elements and
structures complicates correct identifica-tion as well as puts
in question taxonomical status of the species. Studies of larval
ecology, morphology and conditions of the development for each
species of the genus allowed reliable confirmation of their taxonomical
status and to reveal likely causes, which promote morphological
variation of these species in phylogenesis.
Key words: horseflies, genus Philipomyia, variability, larvae,
ecology, morphology, taxonomical status.

Haemopoietic System of
the Anurans: the Role of Bone Marrow and Liver. Akulenko N. M.
— The haemopoietic activity of the frog, Pelophylax ridibundus
was investigated during the year. Liver and bone marrow myelograms
were examined in the different seasons using the special indexes
and coefficients. It was shown the presence of the erythroid and
granulocytic differentiation during the year in the both organs.
In the bone marrow is changing the total number of the non-diferentiated
haemopoietic cells, but ratio between erythroid and granulocytic
progenitors is stabile. The haemopoietic activity of the liver
has more prominent season variation in comparison with the marrow,
but their total significance is comparable. The erythrocytic differentiation
is more prominent during the summer and autumn, but granulocytic
one took place in the spring and summer.
Key words: haemopoiesis, anuran.

Distribution of Tick
Haemaphysalis punctata (Acari, Ixodidae) in Ukraine. Akimov I.
A., Nebogatkin I. V. — The northern boundary of H. punctata
range was studied. This boundary of its native range (where this
species is common and its mass reproductions are periodically
recorded) was found to go through Odesa, Mykolaiv, Kherson, Zaporizhia,
Donetsk and Lugansk oblasts. Clarified that the boundary of its
temporary range (where this species occurs periodically and is
dependent on human factors totally) was clarified to go through
Volyn, Rivne, Zhytomyr, Kyiv, Chernihiv and Sumy regions. The
range of H. punctata is fully subjected to anthropogenic factors
in areas where this species dwelt in historically recent times
only, and in ancestral areas of distribution such factors affects
only dynamics and indices of abundance.
Key words: Haemaphysalis punctata, distribution, Ukraine.

Echinopla cherapunjiensis
sp. n. (Hymenoptera, Formicidae) from India. Bharti H., Gul I.
— Echinopla cherapunjiensis Bharti et Gul, sp. n. is described
from India. This represents the second species of genus reported
in India, with only Echinopla lineata senilis Mayr, 1862 described
earlier from Nicobar Islands. The species distinctly differs from
all other known species of this genus by the following combination
of characters: globose shape of head, presence of seven teeth
on petiolar scale, flat dorsum of mesosoma with promesonotal and
mesometanotal sutures obsolete, whole body surface (dorsum) rough
due to sinuous sculpture, deep excavations and spiky elevations
on head and mesosoma and excavations on gaster.
