The publication dates are 1820 and 1838 for Lafoea dumosa (Fleming) and Aeginopsis laurentii Brandt, respectively. The last name is given precedence over its unused objective synonym Ae. horensis Brandt, 1834.

Morphology, biology and taxonomy of the nematode family Ceramonematidae Cobb, 1933 are summarised and reviewed. Plesiomorph-apomorph polarities of cuticle sculpture, cephalic sensilla pattern, amphid shape are revealed with use of the out-group comparison and ontogenetic observations. The genera Ceramonema and Pselionema are distinguished by the most apomorph character states; both genera combined comprise the greatest number of species, of the widest overall ecological range. The other ceramonematid genera display more plesiomorph character states and contain much less speces; these are strictly confined to coars sand. Ceramonematidae are related to the families Diplopeltoididae sensu Tchesunov (1990) and Tarvaiidae. The family Ceramonematidae consists of two subfamilies: Ceramonematidae with the genera Ceramonema (= Ceramonemoides, = Cyttaronema), Dasynemella (=Leptodasynemella), Dasynemoides (=Dasynemelloides), Metadasynemella (=Dictyonemella), and Metadasynemoides, and Pselionematinae with the genera Pterygonema and Pselionema (= Pselionemoides). Modified diagnoses of the family, subfamilies and genera are given. Separation of higher ceramonematid taxa is based largely on features of body cuticle annulation as well as on anterior sensilla pattern, while cephalic ratio and finer details of body annulation are important for species discriminaton. Annotated lists of species are given for each genus. The genus Ceramonema is subdivided into two subgenera, Ceramonema s. str. (body cuticular annules with zygapophyses) and Proceramonema subg. n. (body annules devoid of zygapophyses). New species from the With Sea (Ceramonema fluctuosum sp. n., C. marisalbi sp. n., C. mokievskii sp. n., Dasynemoides crassus sp. n., Metadasynemoides labiatus sp. n., Pselionema concinnum sp. n., P. mirabile sp. n.) are described. Dasynemella riemanni Haspeslagh is recorded for the first time the With Sea. The description of Pselionema simplex De Coninck from the White Sea is supplemented with notes on juveniles.

Intoshia linei Giard is found in the Barents Sea and I. variabili (Aleksandrov & Slyusarev) registered both in the Barents and White Seas.

Eight species of the families Selachinematidae and Richthersiidae are found in the White Sea, North Russia. The new species, Gammanema anthostoma sp. n., is distinguished by the peculiar chelostomal rugae protruding from the mouth. Its males differ from the males of all Gammanema species in the lack of supplementary organs. Females of G. anthostoma sp. n. differ from those of the two Gammanema species whose males are hitherto unknown: from the females of G. mediterraneum Vitieello, 1970 in the lacking long somatic setae, value of the b index and three times longer body; and from females of G. cancellatum Gerlach, 1955 in the lenth ratio of the outer labial and cephalic setae. Six swpecies (Choniolaimus panicus, Gammanema fennicum, G. rapax, Halichoanolaimus robustus, Latronema aberrans, Richthersia inaequalis) are recorded from the White Sea for the first time. G. fennicum is ressurected as a good species and its male is described for the first time; this species is strongly sexually dimorphic. G. rapax is a very variable species or even a group of species, as its redescriptions differ in important details: its wide distribution needs confirmation. In males of Latronema aberrans, the spermatozoa are filiform unlike rounded spermatozoa of other selachinematids.

Two new species of the genus Metriogryllacris from the Southern Ryukyus are described.

The morphology and taxonomy of free-living nematodes of the genus Diplogasteritus Paramonov, 1952 are studied using the original material and literary data. The diagnosis of the genus Diplogasteritus is emended. Description of species, synonymy and a key to species are given. The following new synonymies are established: D. occidentalis (Steiner, 1932) = D. concolor (Massey, 1962) = D. austriacus (Fuchs, 1938); D. lineatus (Fuchs, 1915) = D. angustialaimus (Sch. Stekhoev & Tenuissen, 1938) = D. likoi Kokordak, 1963 = D. consorbinus (de Man, 1920) = D. stoeckherti (Volk, 1950) = D. taedus (Massey, 1962); D. nudicapitatus (Steiner, 1914) = D. aquaticus Gagarin, 1977 = D. ponderosus (Massey, 1962). Diplogasteritus arcuatus (Massey, 1962), D. brevicaudatus (Sch. Steckhoven & Tenuissen, 1938), and D. minutus (Kreis, 1929) are considered species inquirendae. Diplogasteritus paxi (Paesler, 1962), D. pterygatus (Timm, 1961) and D. subterraneus (Hnatewytsch, 1929) are considered species incertae sedis. Diplogasteritus primitivus sp. n. collected from rotten potatio in Yaroslavl Prov. of Russia is described and illustrated.

G. altaica sp. n. from Russia is close to G. longicaudata, but differs in the shorter cephalic and labial setae and in the ratio vulva-anus distance to anal diameter. G. australis (Cobb, 1893), G. breviseta (Brzeski, 1993), G. mexicana (Brzeski, 1993), G. longicaudata sp. n., G. media sp. n., G. altaica sp. n. are very similar and form within the genus the G. australis species-group. A key to species of this group is given.

Theristus pannonicus Andrássy, 1985 is redescribed from mature females and males collected in the Ukrainian Carpathians.

The synonymy of Ch. taeniopus gotlandica Holmgern, 1887 with Ch. pumilionis (Bjerkander, 1778) is confirmed. The names Ch. discicornis Zetterstedt, 1848 and Ch. taeniopus gotlandica Holmgern, 1887 were overlooked by all or nearly all authors dealing with Chloropidae.

The monotypic weevil tribe Neosharpiini Hoffmann, 1956 is herein placed in the subfamily Baridinae. Elasmobaris capucinus Faust, 1881 is transferred to Neosharpia Hoffm., and is probably synonymous with Neosharpia artemisiae Hoffm. In addition to Neosharpia, the genus Eumycterus Schoenh. is placed in the Neosparpiini. E. albosquamulatus Boh. is recorded for the first time from Middle Asia, Iran, and Ethiopia. Baris alboguttata Bris. is designated as type species of Elasmobaris Reitt.

Exeristes roborator (F.) and Xylophrurus ?nigricornis (Thomson) are for the first time recorded from Northeastern Turkey. E. roborator was reared from five species of the weevil genera Larinus Dej. and Rhinocyllus Germ, developing in flowerheads of Asterceae, and one species of the genus Lixus F., developing in the stem of Polygonacaeae. The single specimen of X. ?nigricornis emerged from the larva of Lixus ochraceus Boh. developing in the stem of a crucifer. All weevils belong to the weevil subfamily Lixinae (=Cleoninae) (Coleoptera, Curculionidae).

A new genus and species of Carangidae, Uylyaichthys eugeniae gen. et sp. n., is described from the Upper Paleocene (middle part of the Danata Formation) of Turkmenistan. It belongs to the subfamily Trachinotinae s. str. and differs from all known members of the family in the combination of low vertebral count (21 or posibly 22), paraspenoid strongly curved mesially, and unique predorsal formula 0/0+0+0/1/. Uylyaichthys is considered to be a sister taxon for Trachinotus + Paratrachinotus, and Trachinotinae s. str. regarded as a sister group of Scomberoidinae. The genus Lichia is excluded from Trachinotinae s. str. and considered to be a sister taxon of Scomberoidinae + Trachinotinae s. str.

A new genus and species of Trichiuroidea, Argestichthys vysotzhyi gen. et sp. n., is described from the Upper Paleocene (middle part Danata Formation) of Turkmenistan. This genus is characterised by several unique derived characters in the structure of body lateral-line system, axial skeleton and jawq dentition, and similar to the Trichiuridae in several advanced characters (single supernumerary spine on first anal pterygiophore, extremely reduced supraoccipital crest, and presence of a pair of anteriorly directed canines on premaxillary). Many primitive characters of the new genus (body shape, low number of vertebrae, structure of suspensorium, opercular series, unpaired fin girdles, etc.) do not occur in the Trichiuridae, but are shared by the new genus with Gempylidae. The new genus also resembles the gempylid Ruvettus in the abdominal position of the first two anal pterygiophores. Therefore, Argestichthys is placed in Trichiuroidea incertae sedis.

Xeuxia cinerea Meigen is for the first time recorded from Northeastern Turkey. The tachinid was reared from four new hosts, all species of the weevil genera Larinus Dej. and Rhinocyllus Germ. (Coleoptera, Corculionidae: Lixinae).

Petroleuciscus gen. n. (type species Squalius borysthenicus Kessler, 1859) is erected for 6 species from the former subgenus Squalius of the genus Leuciscus (= Leuciscus cephalus complex sensu Bianco, 1983). It is distinguished by the reduced number of vertebrae (total vertebrae modally 34-38), few sensory cephalic pores (7-10 in the supraorbital canal), relatively small supraethmoid-mesethmoid block, narrow infraorbitals, and deep neurocranium with a normally developed interorbital septum.

The generic status of Galsania Richter is resurrected; the name is not a junior synonym of Goniocera B. & B.

Individual variation of the size and plumage colour in three type specimens of Middendorff’s Grasshopper Warbler, Locustella ochotensis is examined, the dates and localities of collecting are defined more exactly and the lectotype is designated. Examination of allpreserved specimens, collected by Middendorff, and of the original description show that he misidentified adult birds of L. ochotensis as L. certhiola. This is imorotant for understanding of the diagnosis of L. ochotensis based on characters of young birds in juvenile plumage.

Present taxonomic status and synonymy of the didelphic species of the genus Radopholus Thorne are considered. A monoentry polytomous key to Radopholus is presented, as well as the rows of characters and a matrix of species and characters which were used for the phylogenetic analysis in the PAUP package. Phylogenetic tree of the genus includes four main species groups (clusters); all the species of the Indo-Asian origin (not inhabiting Australia and Oceania) form a separate monophyletic branch. Basing on the frequency analysis of the character states among the species of the genus, the conclusions on the main morphological adaptations of Radopholus are drawn.

A simple method of 1-2 hours technique to prepare permanent collection slides is described and illustrated (normally the slide preparation takes 1-2 weeks). The method may be recommended for cases when the express identification is needed: in quarantine and plant protection services, and as an auxiliary method in molecular and applied investigations, to prove reliability of the species identification after years and future taxonomic changes. The method includes killing, fixation, processing in glycerin, and preparation of slides using an Eppendorf tube at high temperature (60-95 °C).

Status of three generic names is changed into subgeneric (Peltia, Archenopterus, Mundeicus). One tribal name (Adenopterini Otte, 1994) is considered nomen nudum. New synonymy (Promnesibulus syn. n. = Mnesibulus s. str.) is established. Lectotypes for Poliotrella greeni and Varitrella conspersa as well as a neotype for Matuanus priapus are designated.

Colpopterini trib. n. is erected in the subfamily Issinae (type genus: Colpoptera Burmeister, 1835). The subfamily Parahiraciinae Cheng & Yang, 1991 downgraded to a tribe of Issinae (Parahiraciini, stat. n.). The tribe Adenissini Dlabola, 1980 is transferred from Issidae to Caliscelidae. The diagnosis of the family Issidae is refined, and a key to the tribes of the subfamily Issinae is given.

The correct authorship and date for Macrosaldula is Southwood & Leston, 1959.

A comparative morphological analysis of the fleas from the melis-flabellum species group of the genus Paraceras (Siphonaptera, Ceratophyllidae) is undertaken. Differences in the structure of the clasper and the 8th tergite allow considering P. melis and P. flabellum separate species. Morphological characters of the Japanese form of Paraceras make possible to treat it as an independent taxon. The distribution ranges of three badger species of the genus Meles (Carnivora, Mustelidae) are shown to correspond to those of their specific parasites, i.e. the fleas of the melis-flabellum species group of the genus Paraceras. Paraceras melis is restricted to the range of the European badger, Meles meles (Europe, the Caucasus, northern Iran and southern Kirgizia), while Paraceras flabellum is limited by the range of the Asian badger, Meles leucurus (Kazakhstan, Middle Asia, Siberia, China).

The names hitherto proposed for the Ussurian subspecies of Sorex tundrensis Merriam, 1900 (S. t. ussuriensis Okhotina, 1983, S. t. stroganovi Okhotina, 1984, S. t. stroganovi Yudin, 1989) are preoccupied. A new name, Sorex tundrensis khankae, is proposed for this taxon.
