The Problem of the Suctorians (Ciliophora, Suctorea) Origin.
Dovgal I. V. — The basic hypotheses of suctorians origin are discussed in
the article. The emphasis is on the tentacle as the most typical suctorian organelle.
Based on the comparative analysis both ultrastructure and function of feeding
organelles in suctorian and rhynchodid ciliates was conclusioned that the recent
hypothesis about the affinity between mentioned ciliate groups is little justified.
The conjectured resemblance of suctorian and rhynchodid tentacles structure actually
is in appearance only. The homologues or analogues of suctorian tentacle was not
found among tentacle-like organelles of other taxa of infusoria. In turn the modes
of feeding that are closely resemble that in Suctorea were formed independenlty
in the different flagellate groups. It may be inferred that the possible homologues
of suctorian tentacles should be searched among ciliates with mode of feeding
that similar to mentioned carnivorous flagellates. The free-swiming predatory
ciliates with mode of feeding that similar to didiniid ciliates are discussed
as possible ancestors of suctorians.
Key words: suctorians, origin, tentacle, feeding.

Liometopum microcephalum (Hymenoptera, Formicidae)
in the Lower Dnepr. Makarevich O. N. — Liometopum microcephalum Panzer is
the only one ant species included into Red Data Book of Ukraine. Only three populations
of this species were known for the territory of Ukraine, but biology and ecology
were unstudied. We found population settlement of L. microcephalum on the Kozatsky
island of Dnepr river near New Kachovka (Kherson Region). Several biological characters
of L. microcephalum are studied, and its dominant role in multispecies ant community
are shown.
Key words: Liometopum microcephalum, ants, Formicidae, Red Data Book of Ukraine,

On the Find of Acantellae of the Acanthocephalon
Telosentis exiguus in Apherusa bispinosa (Amphipoda, Calliopiidae) in the Black
Sea. Belofastova I. P., Grintsov V. A. — Acantellae of Telosentis exiguus
(v. Linstov, 1901) Van Cleave, 1923 were found in the body cavity of the Black
Sea gammarid Apherusa bispinosa (Bate, 1857) for the first time. Original pictures
and measurements are given.

Schmelziini, trib. n. — a new tribe for hymenolepidoid
tapeworms (Cestoda, Cyclophyllidea). Spassky A. A. — Schmelzia linderi (Schmelz,
1941) Yamaguti, 1959 is an obligate parasite of a bird (Syrrahaptes paradoxus)
living in deserts or semi-deserts of Central Asia and is being removed from the
family Hymenolepididae Perier, 1897, which unites mammal helminths, and from the
genus Microsomacanthus Lopez-Neyra, 1942, which contains the waterfowl cestodes.
Schmelzia Yamaguti, 1959 is designated as a type genus of the tribe Schmelziini,
trib. n., which together with the other cestodes of the terrestrial birds is transferred
to the family Oligorchidae Mayhew, 1925. The latter family includes primarily
atmobiontic cestodes and consists of the following subfamilies and tribes: Oligorchinae,
Capiuterilepidinae, Oligorchini, Capiuterilepidini, Passerilepidini, Echinolepidini,
Hispaniolepidini, and Schmelziini, trib. n. as well. The differentiating characters
for the latter are the unarmed proboscis, the apical glandular hollow organ (vagina
rostelli derivative) and the crystal structure of egg outer shell. The superfamily
Hymenolepidoidea is expanded to include the families Hymenolepididae Peerier,
1897; Fimbriariidae, Wolffhungel, 1898; Echinocotylidae Ariola, 1899; Aploparaksidae
Mayhew, 1925 and Oligorchidae Mayhew, 1925 (subordo Hymenolepidata Skrjabin, 1940).
Key words: cestodes, tapeworms, Hymenolepidoidea, Oligorchidae, Schmelziini, Schmelzia.

The Larvae of Endemic and Rare Horse Flies
Species (Diptera, Tabanidae) from Talysh. Andreeva R. V., Zeynalova Z. A.
— Previously unknown larvae of the three horse flies species are described. Tabanus
talyshi Olsufjev, 1972 is similar to the bifarius group members in main characters
of the group, differing by the shape of concentric area of pubescence on the meso-
and metathoracic segments; the central area of all thoracic segments has no striation
either dorsally or ventrally, a character unusual for edaphobionts, which supports
its species status. Atylotus loewianus Villeneuve, 1920 differs from the few known
larvae of this genus in almost full absence of pubescence. Haematopota caspica
Abbassian-Lintzen, 1960 has certain specific characters, not breaking away from
uniform characters of hitherto known larvae of 16 species of this genus.
Key words: Diptera, Tabanidae, horse flies, Talysh, larvae, characters, ecology.

Morphological variability of the grass snake
(Natrix natrix) in the South of Ukraine. Karmyshev Y. V., Manuilova O. N.
— A population of the grass snake, Natrix natrix (Linnaeus, 1758), in which striped
individuals consist about 50%, was found in the Danube delta for the first time.
While studying 192 adult individuals from 55 localities in the south of Ukraine,
the striped individuals were found to differ in certain external morphological
characters (maximal head width, coloration) from N. natrix natrix. Premilinary
study of distribution and peculiarities of biology shows no reliable differences.
Key words: Natrix natrix, grass snake, systematics, distribution, south of Ukraine.
