The First Record of Aphallus tubarium (Trematoda, Cryptogonimidae) from the Black Sea

Трематода Aphallus tubarium (Rudolphi, 1819) Poche, 1926 зарегистрирована у нового хозяина — иглы-трубкорота (высокорылой) Syngnathus typhle Linnaeus (Pisces, Syngnathidae), выловленной у берегов Крыма. Приведено описание и оригинальный рисунок мариты. Род Aphallus впервые отмечен в Черном море.The trematode Aphallus tubarium (Rudolphi, 1819) Poche, 1926 is found in the new host, the pipefish, Syngnathus typhle Linnaeus (Pisces, Syngnathidae) caught near coast of the Black Sea. Morphological description and figure of trematode are given. The genus Aphallus is recorded from the Black Sea for the first time

SPECTROSCOPIC AND QUANTUM CHEMICAL STUDY OF THE PROPERTIES AND STRUCTURE OF 5-HYDROXYBENZIMIDAZOLE

The MNDO method has been used to calculate the heats of formation of six tautomeric forms of 5-hydroxybenzimidazole (1), their anionic and cationic forms, as well as the energetic, electronic, and structural characteristics of neutral, protonated, and deprotonated tautomers. According to the IR spectra, 1 exists in the crystalline state and in CCl4 and acetonitrile solution in the hydroxy form as two tautomers. A significant difference has been shown to exists in the EAS in acidic media of benzimidazoles, containing a benzene ring in the C2 position, as compared with the spectra of benzimidazoles with alkyl substituents in this position. Spectral characteristics are given which can be used to distinguish the mono- and dianionic forms of derivatives of 1

Two new hemiurine species (Digenea : Hemiuridae) from Spratelloides robustus Ogilby (Clupeiformes : Clupeidae) off south-western Australia and records of Parahemiurus merus (Linton, 1910) from Australian and New Caledonian waters

Two new species of hemiurine hemiurid are described from Spratelloides robustus off Woodman Point in southern Western Australia. Hemiurus lignator n. sp. differs from its congeners by a combination of similar-sized suckers, long sinus-sac, tandem testes, relatively elongate shape and unthickened seminal vesicle wall. Parahemiurus xylokopos n. sp. differs from its congeners in a combination of its squat form, its distinctly lobed vitellarium and the proximity of the gonads to the ventral sucker. P. merus (Linton, 1910) is reported from Acanthopagrus australis, Pomatomus saltatrix and Trachinotus coppingeri off northern New South Wales, Caranx sexfasciatus, Scorpis lineolata, Siganus nebulosus, Thunnus tonggol and T. coppingeri off southern Queensland, Cephalopholis boenak and Euthynnus affinis off Heron Island, southern Great Barrier Reef, P. saltatrix off southern Western Australia and Priacanthus hamrur off New Caledonia
