Revision of the Terellia virens Group (Diptera, Tephritidae) with Description of Three New Species. Korneyev V. A., Evstigneev D. A., Karimpour Y., Kutuk M., Mohamadzade Namin S., Omur Koyuncu M., Yaran M. — The Terellia virens group includes eight species of uniformly greenish flies with white setulose abdomens and hyaline wings, variable in the characters of the male and female terminalia. Three new species are described and illustrated: Terellia freidbergi sp. n. from Middle and Near East, from flower heads of Centaurea behen L., T. ivannikovi V. Korneyev et Evstigneev, sp. n. from European Russia, Kazakhstan and Uzbekistan, breeding in flower heads of Ce. chartolepis Greuter, and T. whitei V.?Korneyev et Mohamadzade, sp. n. reared from flower heads of Cousinia spp. in Kazakhstan, Kyrgyzstan, Turkmenistan and Iran. Illustrated diagnoses or redescriptions of other species and a key to the species of Terellia with hyaline wings and white setulose abdominal tergites are given.
Key words: Diptera, Tephritidae, Terelliini, Terellia, key, new species, Palaearctic Region, Centaurea, Cousinia.

Diversity of the Larval Cranial Setae in Palaearctic Notodontidae (Noctuoidea) and and their Taxonomic Distribution. Dolinskaya I. V. — Larval cranial setae of each larval instar of 66 species belonging to 35 genera of Palaeartic Notodontid moths from Ukraine and Far East of Russia (Primorskii krai) was examined with the use of a scanning electron microscope. A comparison with outgroup species — Lasiocampoidea (Lasiocampidae), Sphingoidea (Sphingidae) and Noctuoidea (Erebidae: Lymantriinae, Arctiinae; Noctuidae) is conducted. Main kinds of setae during larval development and their transformation are discussed. Possible apomorphic and plesiomorphic states of the different characters are discussed in relation to the different taxa.
Key words: Notodontidae, Lepidoptera, larvae, morphology, larval cranial setae, classification, scanning electron microscopy.

The Life Cycles of Mayflies of the Eastern Ukraine. Subfamily Baetinae (Ephemeroptera, Baetidae). Martynov A. V. — The life cycle types of mayflies of the subfamily Baetinae in Eastern Ukraine are determined. The scheme for identification of larval age structure is given. The age structure changes of Baetis braaschi, B. nexus and Alainites muticus larvae during the year are described in detail. The flight periods of imagoes throughout the studied region are delimited for almost all species of the subfamily. B. braaschi is shown to have the bivoltine life cycle, with its populations overwintering as the larval stage (MBws) independently on temperature conditions in the water body. The peculiarities of oviposition are described for this species. The following aspects of life cycles were revealed: nymphs, subimagoes and imagoes of different generations of B. braaschi differ considerably in size; the voltinity of B. vernus in the region can vary (Us and/or MBss), mainly due to temperature conditions of the water bodies, where its development takes place; geographically isolated populations of A. muticus in the Eastern Ukraine reproduce only by thelytoky.
Key words: mayflies, Ephemeroptera, life cycles, bionomy, parthenogenesis, Eastern Ukraine.

The Periodicity and Daily Rhythm of Emission of Cercariae of Particular Trematode Species (Digenea). Zhytova O. P. — The paper covers the investigation into the daily rhythm and periodicity of Echinoparyphium aconiatum Dietz, 1909; Haematoloechus asper Looss, 1899; Plagiorchis elegans (Rudolphi, 1802) Braun, 1902; Notocotylus attenuatus Rudolphi, 1809 cercaria emission of Lymnaea stagnalis (L.) and Planorbarius corneus (L.) mollusks. It has been established that the maximum withdrawal of H. ΰsper, P. elegans, N.?attenuatus, E. aconiatum larvae at different periods of the day is stipulated by the biological peculiaritics of the life cycle of these trematodes.
Key words: freshwater mollusks, cercariae, emission, daily rhythm.

Recent State and Mechanisms of Invasions of Exotic Decapods in Ukrainian Rivers. Son M. O., Novitsky R. A., Dyadichko V. G. — Lower reaches of largest Ukrainian rivers are zones of migrations for exotic euryhaline decapods. During 2000s new records of invasions of three euryhaline exotic decapods, Rhithropanopeus harrisii (Gould, 1841), Eriocheir sinensis Milne-Edwards, 1853 and Macrobrachium nipponense (De Haan, 1849), were made in the channels of Ukrainian rivers. Chinese mitten crab, E. sinensis, spread in the Danube Delta and reservoirs of the Dnieper River; Rh. harrisii — in the channels of the Danube, Dnieper, Southern Bug and small river Gruzskij Yelanchik in the Azov Sea Basin; M. nipponense that was introduced in the Kuchurgan Liman (cooler reservoir of the Moldavian Hydro-power Station) — in the Dniester Delta. The migration zone of the established population can cover significant part of river watershed; it is necessary to take this fact into account at an estimation of biological invasion risk. Main problem in the investigation of exotic decapods in Ukrainian waters is absence of specialized methods used in the standard ecological monitoring. Among euryhaline exotic decapods, only Rh. harrisii is sometimes sampled with the equipment used in the monitoring of macrozoobenthos. A few records of these species at the large extent of their supposed ways of migration are the result of gaps in the study of their distribution in Ukrainian inland waters. Realistic attitude toward this fact is very important for the estimation of invasions in the inland waters of this region.
Key words: invasive alien species, Decapoda, Rhithropanopeus harrissii, Eriocheir sinensis, Macrobrachium nipponense, Ukraine.

Evidences of Multicomponent Structure of the Migratory Stock and Morphological Distinctions of Shads from the Genus Alosa (Clupeaformes, Alosiinae) of the Sea of Azov. Mezhzherin S. V., Vernygora O. V. — Migratory stocks of shads passing through the Kerch strait during their seasonal migrations consist of three groups of specimens, that can be identified based on the number of gill rakers on the first arch. These are so called Kerch shad A. maeotica (50.2 %), Pontic shad A. immaculata (48.7 %) and Caspian shad A. caspia (1.1 %). This ratio of species in the region remains stable for the last 60 years. Populations of Kerch and Pontic shads have similar age structure and sex ratio with a shift toward females 52–54 %. Specimens of A. maeotica have greater linear size and weight than those of A. immacuta, that indicates higher growth rate of the former. Analysis of 26 body measurements shows definite differences between these shads in their absolute features, there are also some differences in the proportions of the head. Nevertheless, degree and reproducibility of interspecific differences during various periods of time, do not allow for the reliable discrimination of specimens of these species assumed by some researchers.
Key words: pontic shad, Alosa, stock structure, morphometry, ecomorphs.

Correlations Between Hardness of Food and Craniodental Traits in Nine Myotis Species (Chiroptera, Vespertilionidae). Ghazali M., Dzeverin I. — We studied 8 skull and 42 dental characters in nine Myotis species (M. myotis, M. blythii, M. bechsteinii, M. dasycneme, M. emarginatus, M. nattereri, M. daubentonii, M. brandtii, M. mystacinus) to analyze correlations between hardness of food and skull and dental traits. Contrary to the common bat pattern, Myotis that are specialized on hard-shelled dietary items tend to have relatively narrow skull and long tooth rows. The dentition of durophagous Myotis is composed by relatively enlarged second and reduced third molars.
Key words: Myotis, hardness of food, skull, teeth.

A New Species of Cloacitrema (Digenea, Philophthalmidae) from Greater Flamingo (Phoenicopterus roseus) with Remarks on the Genera Cloacitrema and Pygorchis. Schuster R. K. — Cloacitrema dubaiensis Schuster, sp. n. is described from four adult specimens found in the cloaca of greater flamingos in Dubai, UAE. It is the first Cloacitrema species found in the Afrotropic ecozone. The new species is medium-sized and slim, with the ventral sucker in equatorial position and the uterus that extends laterally to intestinal caeca. It has oval, unlobed, touching each other testes in parallel to slightly oblique position. C. dubaiensis resembles C. narrabeenensis but differs in body shape, position of acetabulum, size of the seminal vesicle and number of vitelline follicles and their extension lateral to caeca.
Key words: Cloacitrema, new species, Digenea, Philophthalmidae, Phoenicopterus roseus, the UAE.
