B. & Brajković, 2003 are regarded as junior synonyms of the genus Duvalius Delarouzée.     

Key for European species of the Cheilosia proxima group (Diptera,Syrphidae) with a description of a new species

A new hoverfly species, Cheilosia barbafacies Vujić & Radenković sp. n. (Diptera, Syrphidae), is described and distinguished from the closely related species Cheilosia pascuorum Becker, 1894, based on material collected from the mountains of the Balkan Peninsula. Diagnostic characteristics and an identification key for the members of the proxima group of Cheilosia s. str., including the new taxon, are provided.     

New water mites of the family Hygrobatidae (Acari,?Hydrachnidia) from Turkey

In this study, the findings of three water mite species of the family Hygrobatidae collected from different streams in Turkey were evaluated. Hygrobates (s. str.) anatolicus Esen & Pešić, sp. n. is described as new for science. Hygrobates (Rivobates) diversiporus Sokolow, 1927 and Atractides (s. str.) nikooae Pešić, 2004, which were illustrated and thoroughly discussed, are new records for the Turkish fauna.     

Phyllonorycter medicaginella (Lepidoptera, Gracillariidae) and its parasitoids (Hymenoptera, Eulophidae) in the Middle Volga River basin

Fifteen species of parasitoids, Chrysocharis idyia (Walker, 1983), Ch. laricinellae (Ratzeburg, 1848), Ch. submutica Graham, 1963, Ch. viridis (Nees, 1834), Hemiptarsenus ornatus (Nees, 1834), Neochrysocharis formosa (Westwood, 1833), Pediobius cassidae Erd?s, 1958, P. metallicus (Nees, 1834), Pnigalio nemati (Westwood, 1838), P. mediterraneus Ferriére & Delucchi, 1957, P. pectinicornis (Linnaeus, 1758), P. soemius (Walker, 1839), Rhicnopelte crassicornis (Nees, 1834), Sympiesis gordius (Walker, 1839), and Hyssopus sp. n., were reared from Phyllonorycter medicaginella on Melilotius offlcinalis for the first time. Hyssopus simbirskiensis sp. n. reared from Ph. medicaginella is described. Eight ectoparasitoid species (Hyssopus ornatus, H. simbirskiensis sp. n., Rh. crassicornis, P. mediterraneus, P. nemati, P. pectinicornis, P. soemius, and S. gordius) attack all the larval instars of Ph. medicaginella. Seven endoparasitoids (P. cassidae, P. metallicus, Ch. idyia, Ch. laricinellae, Ch. submutica, Ch. viridis, and N. formosa) attack only the 4-5th-instar larvae.     

Caddisflies (Trichoptera) of the protected territories of Belarus

The caddisfly fauna of 13 protected areas in Belarus is studied. A total of 97 species from the following 12 families are recorded: Hydroptilidae (6 species), Ecnomidae (1), Polycentropodidae (11), Pshychomyidae (1), Hydropsychidae (5), Phryganeidae (12), Brachycentridae (1), Limnephilidae (41), Sericostomatidae (1), Molannidae (1), Beraeidae (3), and Leptoceridae (14). Polycentropus kingi McLachlan, 1881; Agrypnia picta Kolenati, 1848; Limnephilus sericeus (Say, 1824); L. dispar McLachlan, 1875; L. elegans Curtis, 1834, and Hagenella clathrata (Kolenati, 1848) are rare in Europe. Some of the revealed species are critically endangered in several countries of western Europe. The studied protected areas play an important role in conservation of species diversity and in the distribution of several rare species.     

Metal accumulation by the ultramafic flora of Kosovo

The largest serpentine outcrops in Europe occur in the Balkan Peninsula. Kosovo, as a part of this region, hosts an ultramafic area of 487 km² within its territory. This work reports the first systematic biogeochemical survey on the significant and most representative ultramafic massifs of Kosovo. The aim of this study was (i) to detail the geochemical composition of 12 ultramafic pedons obtained from 10 selected sites chosen as representative for Kosovo, (ii) to inventoriate the flora occurring on these sites and (iii) to identify plant species with potential for use in phytostabilization or phytoextraction purposes. Twelve representative pedons from 10 different sites across the country were excavated and 27 horizon samples were collected. Regarding the serpentine flora, a total of 162 plant taxa located at the ultramafic sites were collected. Soils samples were characterized for basic physico-chemical characteristics and both plant and soil samples were analyzed for chemical composition. The serpentine soils samples displayed a vast array of physico-chemical characteristics which reflected the geochemistry of the bedrock, the degree of weathering and the horizon characteristics. However there appeared to be a relationship between edaphic properties and the occurrence of several plant species. Although most of the plants’ species did not show metal concentrations above 1000 mg kg^?1, Odontarrhena muralis (syn. Alyssum murale Waldst. and Kit). and Noccaea ochroleuca (Boiss and Heldr.) F.K.Mey. (syn.Thlaspi ochroleucum), did, thus meeting the criterion of Ni hyperaccumulating plants. Given the aforementioned, the resilience of these plants to both tolerate and accumulate heavy metals may prove useful for phytostabilization,     

Additions and Corrections to the Check-List of the Aphidiid- Wasp Subfamily Aphidiinae (Hymenoptera,Aphidiidae) from the North-West of Russia

New material of the aphidiid-wasp subfamily Aphidiinae (Hymenoptera, Aphidiidae) from the North- Western region of Russia is reported. Aphidius eglanteriae Haliday, 1834 is recorded from this region for the first time. The following corrections to the preceding publication of 2017 have been made: 2 correctly identified specimens of Pauesia abietis (Marshall, 1896) were erroneously given also among the material of P. pini (Haliday, 1834), and 4 specimens of P. similis Starý, 1966 were misidentified as P. pini.     

A new subgenus and a new species of the tenebrionid genus <Emphasis Type="Italic">Leptodes</Emphasis> Dejean, 1834 (Coleoptera,Tenebrionidae)

The genus Leptodes was erected by Dejean (1834) for a single species, Sepidium boisduvalii Zubkoff, 1833, which is, consequently, the type species by monotypy. Kaszab (1959) established in Leptodes the subgenus Leptodinopsis based on the same type species, Sepidium boisduvalii. Thus the names Leptodes and Leptodinopsis are objective synonyms: Leptodes Dejean, 1834 = Leptodinopsis Kaszab, 1959, syn. n. A new subgenus Mesoleptodes G. Medvedev et Iljina subgen, n. (type species Leptodes semenowi Reitter, 1892) is established for species which Kaszab included in Leptodes s. str. A new species, Leptodes daghestanicus G. Medvedev et Iljina, sp. n., is described from Daghestan.     

New or Little-Known Beetle Species (Coleoptera) of the Families Histeridae and Scarabaeidae in the Faunas of Ciscaucasia,Western and Southeastern Kazakhstan

New data are presented on the distribution of Histeridae and Scarabaeidae in Russia and Kazakhstan. Three species, Pholioxenus schatzmayri J. Müller, 1910, Mendidaphodius linearis (Reiche et Saulcy, 1856), and Onthophagus ponticus Harold, 1883, are recorded from Kazakhstan for the first time, and one species, Atholus scutellaris (Erichson, 1834), is new to the fauna of Russia. The distribution ranges are refined for Microsaprinus therondianus (Dahlgren, 1973), Hypocacculus biskrensis (Marseul, 1876), Paravolvulus refector (Reitter, 1904), Hister megalonyx Reichardt, 1922, Bodilus longipennis (Rakovi?, 1984), Protaetia cyanescens jacobsoni (Kiseritzky, 1910), and Valgus hemipterus (Linnaeus, 1758). All these species are distributed mainly in the four zoogeographical regions: Hesperian, European, Saharo-Gobian (Sethian), and Scythian.     

Qualitative study of Mollusca communities in the Serbian Danube stretch (river km 1260–863.4)

First detailed limnological study was performed from April 2003 to June 2008 in a 396.6 km long section of the Serbian Danube (divided in three parts; from 1260 r-km to 863.4 r-km) to examine community composition and spatial distribution of Mollusca with special attention to the expansion of Ponto-Caspian species, propagation of invasive and introduced species and occurrence of endemic species. Mollusca samples were collected at 15 sites in April, June, September and November. We investigated the spatial distributions and calculated the faunistic similarity of localities with respect to the community composition using the Sørensen Quotient of Similarity. Site variation in analyzed qualitative traits was examined using correspondence analysis. Additionally, the obtained Complete Linkage City-block (Manhattan) distances among sites/parts were subjected to UPGMA (unweighted pair-group method using arithmetic averages) cluster analysis. The class Gastropoda was represented by 18 species from two subclasses (Prosobranchia — six families and Pulmonata — three families).The class Bivalvia was represented by 15 species from four families of order Eulamellibranchiata. Mollusca were represented by 33 species belonging to 17 genera and 13 families. Out of five recorded Ponto-Caspian species in the studied Danube stretch, Lithoglyphus naticoides (Pfeiffer, 1828) and Dreissena polymorpha (Pallas, 1771) are assumed to be invasive species with the highest occurrence frequency (F = 1, each). Four new species in invertebrate fauna for the Danube, denoted as the introduced species — Neozoa, were identified: Theodoxus fluviatilis (L., 1758), Corbicula fluminalis (Müller, 1774), C. fluminea (Müller, 1774), and Sinanodonta woodiana (Lea, 1834). The only endemic species of Gastropoda found in the Danube was Viviparus acerosus Bourguignat, 1862.     

Revision of the Indo‐African Pachycerus Schoenherr, 1823, with a description of four new species (Coleoptera: Curculionidae: Lixinae)

The Indo‐African species of the genus Pachycerus (Curculionidae: Lixinae: Cleonini) are revised. The identification of Cleonus senegalensis Gyllenhal, 1834 is discussed, its holotype rediscovered and the synonymy between C. senegalensis and Ammocleonus hieroglyphicus (Olivier, 1807) is confirmed. A neotype is established for Pachycerus opimus (Gyllenhal, 1834). Lectotypes for Pachycerus vestitus (Fåhraeus, 1834), Pachycerus badeni (Faust, 1888), and Pachycerus sellatus Faust, 1904 are designated. Pachycerus sahelicus sp. nov. (type locality: Senegal, Bambey), Pachycerus hippali sp. nov. (type locality: Saudi Arabia: Jeddah, Taif), Pachycerus barclayi sp. nov. (type locality: southern India: Manapparai), and Pachycerus simonae sp. nov. (type locality: Morocco, Western Sahara, Cap Boujdour) are described. Some remarks on taxonomy and biogeography of the species are added.     

Molecular phylogenetic assessment of host range in five Dermanyssus species

Given that 14 out of the 25 currently described species of Dermanyssus Dugès, 1834, are morphologically very close to each another, misidentifications may occur and are suspected in at least some records. One of these 14 species is the red fowl mite, D. gallinae (De Geer, 1778), a blood parasite of wild birds, but also a pest in the poultry industry. Using molecular phylogenetic tools we aimed to answer two questions concerning host specificity and synanthropicity: (1) is D. gallinae the only species infesting European layer farms?, and (2) can populations of D. gallinae move from wild to domestic birds and vice versa? Mitochondrial cytochrome oxidase I gene sequences were obtained from 73 Dermanyssus populations collected from nests of wild European birds and from poultry farms and these were analyzed using maximum parsimony and Bayesian inference. Mapping of the observed host range on the obtained topology and correlation with behavioural observations revealed that (1) host range is strongly dependent on some ecological parameters (e.g. nest hygiene, exposure to pesticides and predators), that (2) out of five species under test, synanthropic populations were found only in lineages of D. gallinae, and that (3) at least some haplotypes found in wild birds were very close to those found in association with domestic birds.     

Reactions of some caddis larvae (Trichoptera) to different types of substrate in an experimental stream *

In laboratory experiments with full-grown larvae of three Trichoptera species (Limnephilus rhombicus, Potamophylax rotundipennis and Sericostoma pedemontanum) in an artificial stream, four types of bottom material were provided in combination with various currents. Only L. rhombicus reacted to low current speed (9 cm/sec), moving downstream when a bottom current was present. L. rhombicus and P. rotundipennis showed a distinct preference for pebbles over sand and for coarse pebbles over crushed brick. S. pedemontanum burrowed under pebbles or stones. L. rhombicus showed a distinct tendency to climb onto the dividing gauze or vertical sticks. All three species preferred shaded parts of the experimental stream to the illuminated parts. The results are related to field observations. Limnephilus rhombicus occurs in stagnant and slow-running waters. Potamophylax rotundipennis is restricted to rather fast-running streams with a perpetual flow, while Sericostoma pedemontanum occurs in the same type of stream.     

The genus Rhyacophila Pictet, 1834 (Insecta: Trichoptera) in Kosovo

The Balkan Peninsula is known for its high species diversity, but it is also one of the least known areas of Europe. Many previously inaccessible regions lack reliable faunistic records. There are especially few data available for the highly diverse aquatic insects of the region. To help fill the gap, we conducted an extensive survey to map the Trichoptera fauna of the Republic of Kosovo, an area where faunistic records are extremely scarce. Adult specimens were collected during 2009 and 2010, with light traps and entomologic nets. Of 84 Trichoptera species identified from the 21 investigated stations, 15 belong to the genus Rhyacophila. This makes the genus the most species-rich in Kosovo. Rhyacophila fasciata and R. tristis are widespread in many streams and rivers all over the country, while R. balcanica, R. trescavicensis, R. obtusa and R. bosnica have limited distribution. Ten Rhyacophila species presented in this paper are recorded for the first time on the area of Kosovo. We also provide new data for the disjunctive distribution of R. palmeni in south-eastern Europe, from Kosovo and Croatia.     

New species and two new records of the spider family Theridiidae (Araneae) from Korea

Three theridiid spiders, which are a new species, Neospintharus baekamensis n. sp., and two species new to Korea, Cryptachaea riparia (Blackwall, 1834) and Lasaeola yoshidai (Ono et al., 1991), are described. The illustrations and diagnoses for all of the species are also provided.     

A chromosomal study on Greek populations of the genusApodemus (Rodentia, Murinae) reveals new data on B chromosome distribution

During this study, 94 specimens (51 males, 43 females) of the wood mouseApodemus sylvaticus (Linnaeus, 1758), the yellow-necked mouseA. flavicollis (Melchior, 1834) and the western broad-toothed mouseA. epimelas (Nehring, 1902) from 20 localities of Greece were karyologically examined. The first two species were found to be widely distributed and their otherwise very similar karyotype (2n=48, FN=48) could be clearly distinguished, based on C-banding pattern. The third species appeared to have a more limited geographical distribution and its karyotype was distinguished from that of the previous two species, since it contained two pairs of small metacentric autosomes (2n=48, FN=52). The chromosomal study further revealed that nine individuals ofA. flavicollis possessed supernumerary B chromosomes (2n=49–50, FN=49–50). Meiotic chromosome preparations revealed that in contrast to sex chromosomes and autosomes, B chromosomes do not participate in bivalent formation. On the other hand, no supernumerary chromosomes were found in the studiedA. sylvaticus andA. epimelas material.     

The molecular species of phospholipids of the cold-water soft coral <Emphasis Type="Italic">Gersemia rubiformis</Emphasis> (Ehrenberg, 1834) (Alcyonacea,Nephtheidae)

The chemical structures and contents of 68 molecular species of ethanolamine glycerophospholipids (PE), choline glycerophospholipids (PC), serine glycerophospholipids (PS), and inositol glycerophospholipids (PI) were determined in the asymbiotic soft coral Gercemia rubiformis (Ehrenberg, 1834) from the Sea of Okhotsk by the method of tandem high-resolution mass spectrometry. The major molecular species were 16:1e/20:4 PE, 16:0e/20:4 PC, 20:1/24:5 PS, and 16:0/24:5 PI. This study showed a significant similarity of the polar lipidomes of G. rubiformis and tropical species of alcyonarians with symbiotic microalgae and revealed the basic characteristic of the polar lipidome of these alcyonarians. It was found that the 24:5n-6 and 24:6n-3 acids (chemotaxonomic markers of soft corals) concentrate in the acyl groups of the molecular species of PS and PI, which can be used as molecular lipid markers in the study of the symbiotic and trophic relationships of soft corals.
