Among the results of Russian influence on Czech in the 19th century was the emergence of an active past participle in -(v)ší in Czech. Although not welcomed by all grammarians, this participle continued its existence in Czech until today, becoming mainly a device of archaic and bookish style. In the actual work, the occurence oft the active past participle in -(v)ší in the largest partial corpus of the Czech National Corpus containing journalistic texts is studied. A main result of the study is that apart from a large number of examples from different verbs which show the active past participle on -(v)ší in the studied corpus once or twice and where it is indeed a device of archaic and bookish style, sometimes even of irony and humor, there is a small group of (mainly intransitive) verbs, where this participle functions with considerable frequency in stylistically more neutral contexts of written Standard Czech as the only participle (sometimes as a - stylistically more marked - variant of a more numerous active past participle in -l). In theses cases, it remains overwhelmingly a syntactically unextended direct attribute of a noun. Such active past participle in -(v)ší is to be found most often in sports coverage where it is built from a set of verbs with terminological function.
A new species of lamproglenine copepods, Pseudolamproglena boxshalli sp. n., is described from gills of the cyprinid fish Cyprinion macrostomum Heckel from the Tigris River in Tikreet, north of Baghdad, Iraq. This is the second species of Pseudolamproglena from Iraq and the fourth in the world. It differs from its three congeners mainly in the armature of antennule, maxilla, maxilliped, legs 1-4 and caudal ramus.
The type-material of Psilostomum lineatum Linton, 1928 was re-examined and identified as Podocotyle reflexa (Creplin, 1825). This re-allocation of the type and only species invalidates the genus Psilolintonum that is now considered a synonym of Podocotyle.
Phonochorion Uvarov (Orthoptera: Tettigoniidae: Phaneropterinae) is a little known genus consisting of three species: Ph. satunini, Ph. artvinensis and Ph. uvarovi. The objective of this study is to conduct a thorough distributional, taxonomic and systematic revision of the genus Phonochorion using both bioacustic and external morphological characters. Field surveys indicate that the genus is distributed from the Trabzon region of Turkey to the Khulo province of Georgia however the exact limit of the eastern distribution of the genus remains unknown. Phonochorion species occur only on the northern slopes of the East Black Sea and Lesser Caucasus Mountains. The Coruh Valley, which seprates the East Black Sea and Lesser Caucasus Mountain ranges, seems to be an effective physical and climatic barrier and determines the distribution of these species. Ph. uvarovi can clearly be distinguished from Ph. satunini and Ph. artvinensis by the calling songs of males and external morphological characters. Ph. artvinensis and Ph. satunini differ in several taxonomic characters but the males have virtually identical calling songs. From a character evolution perspective, although geographically more distant, Ph. satunini is more closely related to Ph. uvarovi than Ph. artvinensis. Morphological similarities in several characters indicate Phonochorion to be most closely related to Polysarcus zacharovi and the Poecilimon heroicus-group. Within the genus Phonochorion, song structure and morphological characters clearly indicate Ph. uvarovi to be the basal taxon.
Gangesia parasiluri Yamaguti, 1934 (Cestoda: Proteocephalidae) is redescribed on the basis of adults obtained from the intestine of Silurus asotus Linnaeus (Teleostei: Siluridae) from Lake Suwa, Nagano Prefecture, central Japan. Its life cycle was studied in the field and laboratory. Rostellar hooks of the adults showed a wide variation in number, ranging from 35 to up to 57. Plerocercoids were found in the rectum of Chaenogobius urotaenia (Hilgendorf) and Rhinogobius brunneus (Temminck et Schlegel) (Teleostei: Gobiidae) from the same lake. Procercoids were formed in the haemocoel of Mesocyclops leuckarti (Claus) (Copepoda: Cyclopidae) 7 days post infection at 21-25°C. They developed into plerocercoids in the intestine of Pseudorasbora puntila pumila Miyadi (Teleostei: Cyprinidae), R. brunneus and S. asotus. Plerocercoids from naturally and experimentally infected fishes were fed to S. asotus, from which immature worms were recovered. It is considered that the life cycle involves three hosts: a copepod as the intermediate host in which procercoids are formed, small fish as paratenic hosts which retain plerocercoids and transport them into S. asotus, and S. asotus as the definitive host in which adults develop. Rostellar hooks of the adults were much fewer, much larger and arranged in fewer circles than those of the plerocercoids. It is suggested that the former are newly formed and replace the latter in an early stage of development of plerocercoids into adults in 5. asotus.
Soricinia tripartita Żarnowski, 1955 is redescribed on the basis of specimens from the type host Sorex araneus Linnaeus from Lithuania, Latvia and Russia (Republic of Karelia and Republic of Komi - a new geographical record) as well as from Sorex satunini Ognev and Sorex volnuchini Ognev from Russia (Nalchik Area in the Caucasus Mountains). The strobilar morphology of S. tripartita is compared with that of other hymenolepidid cestodes of shrews with an unarmed scolex and serial development of proglottides in the strobila, i.e. species of Mathevolepis Spassky, 1948, Ditestolepis Soltys, 1952, Spasskylepis Schaldybin, 1964, Ecrinolepis Spassky et Karpenko, 1983 and Diorchilepis Lykova, Gulyaev, Melnikova et Karpenko, 2006. It was noted that S. tripartita does not correspond to any of the known genera. The following unique characters are found for S. tripartita: heteronomous serial strobilation with one or two sterile proglottides at the end of each series in the strobila and the whole copulatory part of the vagina covered with numerous, fine spines. Therefore, the new genus Gulyaevilepis is erected, with Gulyaevilepis tripartita (Żarnowski, 1955) comb. n. as its type and only species. Since the type material of Soricinia tripartita is not known to exist, a neotype from the same host species and from a locality close to the type locality is designated.
Cystacanths of Corynosoma pseudohamanni Zdzitowiecki, 1984 (Palaeacanthocephala: Polymorphidae) are redescribed on the basis of specimens recovered from three species of Antarctic notothenioid fish, Trematomus bernacchii Boulenger, Gobionotothen gibberifrons (Lönnberg) and Notothenia coriiceps Richardson, collected from the Prince Gustav Channel, Antarctica. The cystacanths' morphometry and their internal anatomy including trunk muscles were studied using light and scanning electron microscopy (SEM). The characteristic features of this species such as the length of proboscis and the number of hooks (i.e. 260 hooks arranged in 20 rows with 13 hooks each, including two basal hooks) were confirmed and the intraspecific variability was evaluated. Sexual dimorphism was manifested in the shape of the hindtrunk, and the distribution and extent of the somatic armature only. SEM observations of internal anatomy revealed the detailed organization of trunk musculature.
Dracunculus globocephalus Mackin, 1927 (Nematoda: Dracunculoidea) is redescribed from specimens collected from the mesentery of the snapping turtle, Chelydra serpentina (L.), in Louisiana, USA. The use of scanning electron microscopy, applied for the first time in this species, made it possible to study details in the structure of the cephalic end and the arrangement of male caudal papillae that are difficult to observe under the light microscope. This species markedly differs from all other species of Dracunculus in having the spicules greatly unequal in size and shape, in the absence of a gubernaculum, and in the disposition of male caudal papillae. The validity of D. globocephalus is confirmed, but the above mentioned morphological differences are not sufficient for listing it in a separate genus. This is the first record of D. globocephalus in Louisiana.
Eimeria dorcadis Mantovani, 1966 is redescribed from dorcas gazelle (Gazella dorcas (L.)) from Saudi Arabia. Oocysts were detected in 7 out of 22 faecal samples (32%) using floatation method. The sporulated oocysts are cylindrical, slightly flattened at the micropylar pole, measure in average 32 × 19 μm (27-36 × 16-24 μm), length/width ratio being 1.7 (1.5-2.1). Oocyst wall is 1.2 μm thick, smooth, double-layered; outer layer is slightly thicker, light blue in colour; inner layer brownish, with micropyle in the inner layer and apparently continual outer one, measures 2.2 μm, but lacks a micropylar cap. The sporocyst elongate-ellipsoidal, measures 14 × 8 μm (12-17 × 6-9 μm), length/width ratio being 1.8, with sporocyst residuum as circular compact, coarse, refractile granules. Stieda body is present, while substieda body is absent. Sporozoites banana-shaped, measure 11 × 2.5 μm, each with a large spheroidal refractile body at the wider pole. Sporulation time is 2-3 days at 25 ± 2 °C.
Two fish cestodes, the little-known Eubothrium fragile (Rudolphi, 1802) and E. rugosum (Batsch, 1786), the type species of the genus Eubothrium Nybelin, 1922, are redescribed on the basis of new material from twaite shad, Alosa fallax (Lacépède, 1803), from England and burbot, Lota lota (Linnaeus, 1758), from Russia, respectively. The tapeworms are compared with two other species of the genus, E. crassum (Bloch, 1779) and E. salvelini (Schrank, 1790), common parasites of salmonid fish in the Holarctic. The most notable differential characters are the size and the shape of the scolex (smaller and oval in E. fragile), the shape of the apical disc (four or more indentations in E. crassum), the number and size of the testes (the largest and least numerous in E. rugosum), and the position and size of the vitelline follicles (almost entirely cortical in distribution in E. fragile and E. crassum versus largely medullary in E. rugosum and E. salvelini). A comparison of species has also shown the morphological similarity of the freshwater species (E. rugosum and E. salvelini) on one hand and those of marine origin, E. fragile and E. crassum, on the other, with the latter species occurring also in fresh waters. A key to the identification of the species studied is also provided.
