A new species of Bricelochlorops Paganelli and the first record of Urubambina rufa (Duda) (Diptera: Chloropidae) from Brazil

The subfamily Chloropinae comprises about 442 described species, with only one species recorded from the Brazilian Amazon. The genus Bricelochlorops Paganelli was represented by a unique species from Rio de Janeiro, Brazil. The species Urubambina rufa (Duda) is the only species of the genus Urubambina Paganelli and has been recorded only from Peru. A new species of Bricelochlorops, B. celutae sp. nov., is described here and Urubambina rufa is recorded for the first time in Brazil. Both species were collected in the state of Acre. A key to species of Bricelochlorops is provided.     

A new species of Spauligodon (Nematoda: Oxyuroidea: Pharyngodonidae) in Latastia longicaudata (Sauria: Lacertidae) from Kenya

A new species of Spauligodon , Spauligodon latasticola n. sp., from the intestines of Latastia longicaudata (Lacertidae) from Kenya is described and illustrated. Spauligodon latasticola represents the 47th species assigned to the genus and the 8th species from the Ethiopian region. The new species differs from all but 2 other species assigned to Spauligodon by the presence of a conically tapering tail in the female. The new species is separated from the 2 similar species, Spauligodon garciaprietoi and Spauligodon goldbergi, by the position of the vulva, which is anterior to the esophageal bulb in the new species, at the level of the esophageal bulb in S. goldbergi, and posterior to the esophageal bulb in S. garciaprietoi.     

New records and new synonyms of antlions (Neuroptera, Myrmeleontidae) from China

The antlions from the subfamilies Nemoleontinae and Myrmecaelurinae deposited in the Entomological Museum of the China Agricultural University (CAU) belong to 16 species, among which 11 are recorded for China for the first time. Four species with mostly Oriental distribution are recorded for the first time from the northern localities in Palaearctic China. The Dzungarian faunistic center of antlions with two species recently described from Turan is distinguished. Some species characteristic of Mongolia were found in adjacent China. Occurrence in China of three species, collected by Russian expeditions 100 years ago, is confirmed. Five species described by Yang from China have been synonymized with widely distributed species.     

The dominant fish fauna in the North Sea and its determination

The 224 species of fish reported from the North Sea are regarded as being composed of elements of three faunas—Boreal, Lusitanian and Atlantic, and they can be grouped accordingly on both a number of species and a biomass basis. The estimation of biomass of more than 10 important species is based on stock estimates obtained from population data. For 65 non-standard species the estimate is based on a comparison of catch rates for 'standard'and non-standard species from groundfish survey data. This involves assumption about the relative catchability of different sets of species. For the other species the biomass are computed in different ways. An analysis of the dominant fish fauna in the North Sea is attempted. The fish fauna in the area is analysed in two ways: by the conventional total number of species from each zoogeographic area, and by the biomass of the representatives of each fauna. It is concluded that for establishing the dominant faunal element of fish, biomass is a better index than is the number of species. The dominant faunal element of fish in the North Sea is Boreal.     

A new species of Ascocotyle (Trematoda: Heterophyidae) from the South American sea lion, Otaria flavescens, off Patagonia, Argentina

We describe a new heterophyid species, Ascocotyle (Ascocotyle) patagoniensis n. sp., based on specimens collected from the intestines of the South American sea lion Otaria flavescens from Patagonia (Argentina). Ascocotyle (A.) patagoniensis n. sp. is distinguished from the other species of the subgenus by the number of circumoral spines, which are arranged in 2 rows of 18 to 23. The new species also differs from the other species in having a gonotyl without papillae. The specimens exhibited the widest seminal receptacle described for a species of this subgenus. Species of the subgenus Ascocotyle usually infect fish-eating birds or mammals in freshwater or brackish habitats. Ascocotyle (A.) patagoniensis n. sp. is the first species of the subgenus described from a marine mammal. However, no metacercariae of Ascocotyle spp. were found in 542 marine teleosts from 20 species collected in the same locality. The life cycle of the marine species from the Ascocotyle -complex infecting pinnipeds remains elusive.     

Tropical fungus-feeding Thysanoptera of the genus Macrophthalmo thrips

The genus Macrophthalmothrips is redefined from a study of all the described species. One new species is described from Jamaica, five species are placed in synonymy, and a key is provided to the thirteen species now recognised. Variation in colour and antennal structure is discussed, and notes are given on the biology and distribution of the species.     

Kazachstania jiainicus sp. nov., an ascomycetous yeast species isolated from soil in Taiwan

A new ascomycetous yeast species, Kazachstania jiainicus, is proposed based on two strains isolated from soil in Taiwan. The species is characterized by forming one or two globose spores in each ascus, fermenting glucose and galactose and assimilating few carbon and nitrogen compounds. Genus assignment and distinction of the strains from recognized species is based on ascosporulation and phylogenetic analysis of nucleotide sequences from domains D1/D2 of the large subunit (26S) rRNA gene. Sequence analysis showed that the species was phylogenetically related to the genus Kazachstania. The species was distinct from recognized species of Kazachstania on the basis of carbon and nitrogen assimilation patterns. Based on the characteristics described above, the species is recognized as a novel species of the genus Kazachstania, and the name Kazachstania jiainicus sp. nov. is proposed. The type strain is SF1S05T (=CBS10587T=NBRC 102655T=BCRC 23098T), which was isolated from soil in Jiain, Hualein, Taiwan.     

Flavonoid distribution patterns in Leucanthemum and related species from North Africa

Flavonoid data is reported for 16 species including eight species of Leucanthemum from North Africa, four from Europe and related species in the Chrysanthemum-Leucanthemum complex. Flavonols, especially quercetin, isorhaamnetin, kaempferol, patuletin and spinacetin, are predominant in the North African species. Flavones, which are common in Leucanthemum species in Europe, are of very rare occurrence in the North African species. The relationship of the species based on the distribution of flavonoid glycosides and aglycones from the ray florets is discussed.     

Allopodocotyle chiliticorum n. sp. (Digenea: Opecoelidae) from redlip shiners, Notropis chiliticus, in Basin Creek, North Carolina

Allopodocotyle chiliticorum n. sp. is described from the intestines of redlip shiners (Notropis chiliticus) from Basin Creek, North Carolina. The new species is characterized by circumcecal vitelline fields that are not confluent in the post-testicular space, which distinguishes it from the 3 previously known species of this genus described from freshwater fishes. The new species is characterized further by an elongate vitelline reservoir lying dorsal to the ovary, an ovary as large or larger than the testes, and an excretory vesicle not reaching the posterior testis. A. chiliticorum n. sp. most closely resembles Allopodocotyle lepomis (Dobrovolny, 1939) in body shape, testes shape, and terminal genitalia but is distinguished further from this species by the extent of the intestinal ceca. The new species is the fourth species of Allopodocotyle known from freshwater fishes in North America.     

Description and phylogenetic relationships of Rodentolepis gnoskei n. sp. (Cyclophyllidea: Hymenolepididae) from a shrew Suncus varilla minor in Malawi

Rodentolepis gnoskei n. sp. is described based on specimens obtained from a lesser dwarf shrew Suncus varilla minor collected in the Nyika National Park, Malawi. The new species is one of the smallest hymenolepidids known from African shrews and is morphologically closest to two other miniature hymenolepidids from African shrews, Staphylocystis loossi and S. khalili. The new species differs from both of them by a much smaller strobila size and fewer proglottids. The rostellar hooks in the new species are more numerous and smaller in size than in S. loossi. The rostellar hooks in R. gnoskei n. sp. are almost three times shorter than hooks in S. khalili. The hook shape in both S. loossi and S. khalili is substantially different from that in the new species. Molecular phylogenetic analysis indicates that the new species is close to Rodentolepis fraterna, a parasite of rodents. The new species clearly differs from R. fraterna by the much shorter strobila, larger hooks, relatively longer cirrus sac, rate of proglottid development, the number of eggs per proglottid and parasitism in shrews. Although the new species fits the current diagnosis of Rodentolepis, its generic allocation is provisional and will likely be revised in the future because the type species of Rodentolepis, R. straminea, belongs to a different well supported clade. Thus, a new genus needs to be established for the lineage that includes R. fraterna and R. gnoskei n. sp. However, this systematic rearrangement is not recommended until Staphylocystis pistillum, the type species of Staphylocystis, is included in future phylogenetic analyses. Rodentolepis gnoskei n. sp. is the first tapeworm species reported from shrews in Malawi and the first species of cestode reported from S. varilla minor and any member of Suncus in Africa.     

Basic features of the nemoral curculionid-beetle fauna (Coleoptera,Curculionoidea) from eastern Europe and western Siberia

There are 132 curculionids associated with deciduous trees in eastern Europe and western Siberia. The weevils and bark beetles make up the basis of the fauna, forming almost 80%. The fauna of oak is the richest (64 species). The species composition on the ash-tree (50% are monophages) is highly original. Impoverishment of the species composition from the west to the east is revealed. The fauna declines by 18% from 45 to 55° E. The species composition reduces two times beyond the Urals. The faunal boundaries are revealed from west to east and from east to west. The most significant boundary (47% of the fauna do not pass it) for distribution of species to the east is situated between 40 and 45° E. Two significant faunal boundaries are revealed from south to north. The fauna of curculionids of deciduous trees is formed by four groups of species. The southern European species (54%) and western palaearctic species (40%) dominate. The species composition of the studied territory is similar to the fauna of Middle Europe. Formation of the modern fauna of curculionids of deciduous trees in eastern Europe probably occurred in the Holocene. The western Palaearctic and Transpalaearctic species could have occupied the considered territory since the Late Pleistocene. Southern European species appeared in the considered territory after the Valdai glaciation during the warming in the Atlantic period of the Holocene. Penetration of East Palaearctic species began rather recently (last few decades), probably due to climate warming and economic activities.     

上升流和水团对浙江中部近海浮游动物生态类群分布的影响

依据2010年4月、7月和11月对浙江中部近海上升流海域进行的海洋调查资料,运用定量、定性方法,探讨了上升流对该海域浮游动物生态类群分布的影响.结果表明:3个季节共鉴定浮游动物64种,桡足类占主要优势,包括5个生态类群,分别是暖温带近海种、暖温带外海种、亚热带近海种、亚热带外海种和热带大洋种.在种类数组成上,春季以暖温带近海种为主,夏季则是亚热带近海种和亚热带外海种居多,秋季也是亚热带种居多,其中夏季暖温带种种类数要高于春季和秋季,这一现象与同时期东黄海沿海有所不同,主要是由于上升流将一些在海洋底部度夏的暖温种带至海洋表面造成的.此外,3个季节生态类群都是以近海种为主,表明沿岸流是影响这一海域的最主要的水团.在丰度组成上,4月暖温带近海种占总丰度的98.79％,7月暖温带近海种也是组成丰度的重要部分,10月则是亚热带近海种丰度最高.丰度组成所反映的规律与种类数组成规律一致.上升流的存在导致夏季近海暖温带种大量出现,是影响这一海域浮游动物生态类群组成的重要因素;受长江径流和椒江径流的影响,近海种成为主要生态类群,是这一海域浮游动物的一个重要的生态特征.     

Planthoppers of Delaware (Hemiptera, Fulgoroidea), excluding Delphacidae, with species Incidence from adjacent States

The number of species of planthoppers (excluding Delphacidae) known from Delaware is updated from 7 (in 4 families) to 62 species (in 9 families). Specimen abundance is tallied by county and seasonally by two week intervals. The Chao1 abundance estimator suggests that the true fauna may be 74 species, although species incidence tallied from adjacent states (MD, NJ, PA and DC) suggests that a total fauna of approximately 100 species may be possible. An artificial key is presented to genus and select species with photos of most included taxa.

Taxonomic composition and zoogeographic characteristics of the flea fauna (Siphonaptera) of Russia

255 species and 59 subspecies of fleas from 55 genera of 7 families are known from Russia, which is 30% of the Palaearctic fauna. Additionally, over 187 species of 47 genera from 7 families are known from the neighboring territories of Central and Southern Europe, Transcaucasia, Kazakhstan, Middle Asia, Mongolia, Northeast China, and Japan. 13 species of 12 genera are known only from Russia. Noteworthy is the low percent of endemic species (not more than 4%) and genera (one genus) in the Russian fauna. The principal centers of taxonomic diversity in the Palaearctic, including many endemic species and genera, lie in the Eastern Asian, Central Asian, and Turano-Iranian Subregions, outside Russia and the Euro-Siberian Subregion. The bulk of the Russian fauna is formed by the species and genera of the three largest flea families: Hystrichopsyllidae, Ceratophyllidae, and Leptopsyllidae. The family Ceratophyllidae has the greatest number of genera in the Russian fauna, and Hystrichopsyllidae, the greatest number of species. Western (Western and Western-Central Palaearctic; 84 species from 41 genera of 7 families) and Eastern (Central-Eastern and Eastern Palaearctic; 78 species from 42 genera of 6 families) species are nearly equally represented in the Russian fauna.

Two new species of Phrynopus (Anura: Leptodactylidae) from the Bolivian cloud forests]

We describe two new species of Phrynopus from cloud forests in Cochabamba, Bolivia. The new species are assigned to the P. peruanus group and are characterized by the presence of basal webbing, distinctive coloration, and by having the first finger shorter than the second. The first of these new species was collected near Montepunko in Parque Nacional Carrasco and is known from eight males and six females. Among its distinctive characteristics are round cream-colored glands on its flanks. A second species is known from one male and one female collected near "Zona de Aguirre" near the northwest border of the park. V and X-shaped blotches and a dorsum that is smooth except for dorsolateral and scapular folds characterize this species. Musculature has rarely been described for species of Phrynopus. The species from Montepunko has unusual gular and thigh musculature that is quite unlike other species of the genus.
