The rules of Latin grammar for formation of the genitive case from personal names are discussed and compared with the past and current zoological and botanical practice. Changes of rules for formation of patronymics in various editions of the International Code of Zoological Nomenclature are reviewed. Preservation of the original spelling is recommended as the best way to stabilize the spelling of patronymics.

The following new taxa are established: Cribrolageninae subfam. n. (for Cribrolagena R.W. Jones, 1984, Lagenidae) in the order Lagenida; Daucinoididae fam. n. (for Daucinoides de Klasz & Rerat, 1962) and Chrysalogoniinae subfam. n. (for Chrysalogonium Schubert, 1908 and two other genera, Nodosariidae) in the order Nodosariida; Krebsininae subfam. n. (for Krebsina McCulloch, 1981, Polymorphinidae) in the order Polymorphinida; Turkmenellinae subfam. n. (for Turkmenella Bugrova, 1985) and Cribrolenticulininae subfam. n.

This species causes galls on Salix myrsinifolia (= nigricans, borelias) in Northern and probably also in Central Europe. Sawflies from Scotland and northern England are considired as a subspecies, P. (E.) aestiva harrisoni Benson, 1940, stat. n. Probably, some of its populations were adapted to the subsidiary host plant – Salix purpurea x S. viminalis and S. purpurea.

Townesioninae, a new subfamily of Ichneumonidae, is established for two monotypic East Palaearctic genera: Townesion and Sachtlebenia. Townesion ussuriensis gen. et sp. n. is described. The new subfamily can be easily separated from other ichneumonids by the following autapomorphies: (1) the hind corner of metapleurum (bearing coxal foramen) projecting downward; owing to this, petiolar foramen far removed from the hind coxae and attached high on propodeum; (2) the hind part of tergite 4 abruptly curved downward and with backward directed spines on the hind margin; (3) tergites 5-7 reduced and retracted under apical part of tergite 4. Morphological peculiarites of the new subfamily and its relationships with other ichneumonids are discussed.

The taxonomic position of Neurocrassus Šnoflak, 1945 is discussed. Four new species and one subspecies from the Primorsk Territory (Russian Far East) and Vietnam with the first recognition of females of this genus are described and figured: N. mariae sp. n. (Russia, Vietnam), N. tentorialis sp. n. (Russia, Vietnam), N. fabimaculatus sp. n. (Russia), N. crassinervis sp. n. (Vietnam) and N. rarus indomalayicus ssp. n. (Vietnam). The forma abnormis f. n. of N. crassinervis with unusual absence of enlargement of the male fore wing is described. The new combination Neurocrassus rarus (Belokobylskij, 1982) (from Ontsira) is established. A key to species of Neurocrassus is given.

Syrphophagus rossittenicus sp. n. is described. It is the first case of rearing an encyrtid from aphids of the family Lachnidae in the Palaearctic Region. The new species is believed to be hyperparasitic.

9 species of Chloropidae are recorded from New Zealand (South Island). The genus Lieparella Spencer with the species L. zentae Spencer known earlier only from Australia is reported from New Zealand for the first time. A new species Conioscinella spenceri related to C. badia Hutton and C. speighti Malloch is described from Nelson Prov.

Intra- and intergroup variation of 11 linear and six plumage coloration characters in museum specimens of the Lanceolated Warbler from the mainland (96 specimens) and the Far Eastern islands (37 specimens) were examined. On the average, insular birds appeared to be larger, with more pointed wings than mainland ones. Canonical analisis of linear dimensions showed the geographycal variation to be six times as large as the sex-associated variation. Yellow coloration of the ventral side is not only typical of some young in nestling plumage but also of adults, indicating that plumage coloration in this species is polymorphic. Peculiarities of the spotted pattern and coloration of the under tail coverts made it possible to identify every insular and mainland specimen in all plumages: juvenile, and fresh and worn definitive. In view of this gap in size and colour of plumage along with the geographycal isolation, it is appropriate to recognize the insular subspecies Locustella lanceolata hendersonii (Cassin, 1858), stat. n.

An examination of the Centroheliozoa fauna of the Volga basin is performed. The work was conducted in the Moscow, Yaroslavl, Samara and Astrakhan provinces. Thirteen species of Centroheliozoa were found and illustrated by scanning electron microscopy. Among them 8 species are usual for central Europe; Choanocystis rotundata is recorded in Europe for the first time. Two new species are described: Acanthocystis astrakhanensis (from the Volga outfall) and Pterocystis schulmani (from the Kuibyshev reservior). An emended diagnosis for Raphidocystis lemani is proposed.

A growing number of colonial genera with shell are described in the literature within both epistylid and operculariid groups of Sessilida. An annotated list is presented, and a new genus Shellositon is added to shelled forms outside the classical taxon Loricata. Unlike all known genera of shelled non-loricate sessilids, Shellositon includes only solitary zooids with a large folded shell and small myoneme merged into the thickened shell basis. Its single species S. branchialis lives on Pacific amphipods.

Three new species of commensal sessilene peritrichs are described from talitrid amphipods Orchestia on the Black Sea shore (Opercularia cema sp. n., Entziella orchestis sp. n.) and from gammarid amphipods Anisogammarus on southern Sakhalin (Circolagenophrys anisogammari sp. n.). Taxonomic notes on some other peritrichs include new combinations, new species for well described but still unnamed forms and designations of type species for several genera.

The new species of predaceous nematode from the beech forests of the Carpathians is described. Clarcus patricius sp. n. is close to C. macropapillatus (Mulvey, 1967), but differs from it in the length of the body, spicule size and number of supplements.

Diversibranchius nicolaji gen. et sp. n. is described from the Bay of Peter the Great (Sea of Japan). The species is characterized by simple capillary setae in both rami of parapodia and by 4 pairs of branchia of two types, leaflike and cirrifprm, both with folds of complex structure. Further, each of leaflike gills has two hillocks on the upper surface. Such branchial structure is described for the first time. The species is close to Diplocirrus Haase and D. cf. capensis in particular (Spies, 1975). The latter apparently belongs to a new genus.

Phyllobdellina kozatshenkoi gen. et sp. n., parasitic on the flatfish Clidoderma asperrimum from the Sea of Okhotsk, is described. All individuals examined have the following characteristics: body greatly flattened; trachelosome much narrower than urosome; somites 3-annulate, with four large papillae and a great number of small ones dorsally; posterior crop caeca completely separated; no accessory glands present; bursa very short; conductive tissue absent; ovisacs very long.

The antarcic leech Nototheniobdella sawyeri gen. et sp. n., parasitic in the mouth and on the body surface of bullheads and notothenioids, is described and placed in a new tribe Nototheniobdellini. These leeches have the following features: body cylindrical; trachelosome narrower than urosome; suckers large, rounded; from 12 to 13 pairs of pulsatile vesicles; mid-body somite 6-annulate, with a pair of pulsatile vesicles on B3 annulus; posterior crop caeca fused, with 4 slits; accessory glands present; seminal vesiclens in the form of long loops; 6 pairs of testisacs; ovisacs long, greatlycoiled; conductive tissue and copulatory zone absent.

The genus Globarcturus is clearly distinguished from other genera of the Antarcturus group with multiarticulate flagellum of antenna 2 by combination of such characters as the bulbous pleotelson, presence of a distinct suture between pleonites 1 and 2, lack of eyes, and dorsal, supracoxal and caudal spines. G. angelikae sp. n. is the first representive of arcturid in the hadal zone of Antarctic.

For all above mentioned Cuban leptophlebiid species male and female imagos, subimagos, and nymphs are known. Borinquena, Careospina and Traverina originally described as separate genera are regarded as subgenera of the genus Hagenulus s. l. New diagnoses of the genus Hagenulus s. l. and its subgenera are given, two new subgenera, Turquiophlebia subgen. n. and Poecilophlebia subgen. n., are described. For the genera Farrodes and Hagenulus s. l. a new tribe, Hagenulini tribus n., is established.

It is shown that Kuwayamaea Matsumura & Shiraki, 1908 (Phaneropterinae) should be considered as separate genus with two species: K. sapporensis Matsumura & Shiraki, 1908 and K. chinensis (Brunner-Wattenwy, 1878). The first name is ressurected from synonymy with K. chinensis. A neotype of the latter species is designated. Ducetia strelkovi sp. n. (Phaneropterinae) from China and Decta (Idiodecma) improvisum sp. n. (Meconematinae) from Korea are described.

Three supraspecific taxa of the tribe Platynini from SW China and adjacent areas are considered. The validity of the genus Andrewesius Jedlička, 1932, is confirmed, its specific composition determined and two new species described: A. fedorovi sp. n. from Yunnan and A. omeishanicus sp. n. from Sichuan. Polychaetagonum gen. n., type species P. plurisetosum sp. n., and two other new species belonging to the genus, P. chensicieni sp. n. and P. inexspectatus sp. n., all the three from the upper belt of Omeishan Mt. (Sichuan) are described; a key to the three species of the genus is provided. The genus Klapperichella Jedlička, 1955 is examined and K. melanoxantha sp. n. is described from Yunnan; it has a stricing dimorphism in coloration. Platynus setiporus Reitter, 1893, from “Buchara” is redescribed; the author believes it to belong to the E Asiatic genus Colpoides Jedlička, 1931, and its actual provenance to be from China.

A new subgenus Berberonyx subgen. n. of the genus Theodorinus is established for Oxyonyx latipennis Pic (type species) and Theodorinus peyerimhoffi sp. n. from Morocco.
