Integrative taxonomy of Leptonetela spiders (Araneae,Leptonetidae), with descriptions of 46 new species

Extreme environments,such as subterranean habitats,are suspected to be responsible for morphologically inseparable cryptic or sibling species and can bias biodiversity assessment.A DNA barcode is a short,standardized DNA sequence used for taxonomic purposes and has the potential to lessen the challenges presented by a biotic inventory.Here,we investigate the diversity of the genus Leptonetela Kratochvíl,1978 that is endemic to karst systems in Eurasia using DNA barcoding.We analyzed 624 specimens using one mitochondrial gene fragment (COI).The results show that DNA barcoding is an efficient and rapid species identification method in this genus.DNA barcoding gap and automatic barcode gap discovery (ABGD) analyses indicated the existence of 90 species,a result consistent with previous taxonomic hypotheses,and supported the existence of extreme male pedipalpal tibial spine and median apophysis polymorphism in Leptonetela species,with direct implications for the taxonomy of the group and its diversity.Based on the molecular and morphological evidence,we delimit and diagnose 90 Leptonetela species,including the type species Leptonetela kanellisi (Deeleman-Reinhold,1971).Forty-six of them are previously undescribed.The female of Leptonetela zhai Wang & Li,2011 is reported for the first time.Leptonetela tianxinensis (Tong & Li,2008) comb.nov.is transferred from the genus Leptoneta Simon,1872;the genus Guineta Lin & Li,2010 syn.nov.is a junior synonym of Leptonetela;Leptonetela gigachela (Lin & Li,2010)comb.nov.is transferred from Guineta.The genus Sinoneta Lin & Li,2010 syn.nov.is a junior synonym of Leptonetela;Leptonetela notabilis (Lin & Li,2010) comb.nov.and Leptonetela sexdigiti (Lin & Li,2010) comb.nov.are transferred from Sinoneta;Leptonetela sanchahe Wang & Li nom.nov.is proposed as a replacement name for Sinoneta palmata (Chen et al.,2010) because Leptonetela palmata is preoccupied.     

Pollen Morphology of Tundra Shrubs and Submarginal Plants from Barrow, Alaska

Investigation of plant morphological features, pollen, and habitat have been made for two shrub species from Barrow, Alaska, namely Dryas integrifoila M. Vahl and Salix rotundifolia Trautv., both of which are endemic to the Arctic floristic area. The former species has small lanceolate or plate leaves, whereas the latter has rounded leaves with distinct veins, rich in vitamin C. Both have dwarf and sprawling habits. Pollen studies showed that the pollen grains of the two species are spheroidal to sub-spheroidal or prolate. The type of aperture was tricolporate; pollen size 26.3-31.3 μm; ornamentation finely reticulate under a light microscope （LM） and strlate-reticulate under a scanning electron microscope （SEM） for D. integrafoila and finely reticulate under the LM and SEM for S. rotundifolia. Comparisons were made between the pollen from the same species from Arctic collections with those from China and Japan. Investigation of pollen morphology of tundra plants can provide significant data for comparative studies of fossil pollen and for the reconstruction of paleovegetation and paleoclimate in the Barrow area.

杜鹃花属映山红亚属的花粉形态及其系统学意义

Eighty-four pollen samples were obtained for 80 taxa, of which, 13 species and one variety are from sect. Brachycalyx Sweet, 58 species and two varieties from sect. Tsutsusi Sweet, and six species from subgen. Pentanthera （G. Don） Pojarkova, respectively. Pollen morphology of all samples was observed using LM and SEM. Pollen grains are revealed to be spheroidal and tetrahedral with tricolporate apertures. Pollen sizes of subgen. Tsutsusi （Sweet） Pojarkova range from 37.67 μm to 61.06μm, and the exine sculptures are more or less compactly granulated. Pollen sizes are significantly different between sect. Brachycalyx and sect. Tsutsusi of subgen. Tsutsusi. Rhododendron tashiroi Maxim. of sect. Tsusiopsis Sleumer shows a close affinity to sect. Brachycalyx. Pollen size and exine are consistent with general morphology in differentiating species in sect. Tsutsusi. Rhododendron huadingense B. Y. Ding ＆ Y. Y. Fang, once placed as a member of sect. Brachycalyx, should be considered as a species in subgen. Pentanthera.     

NOTES ON THE CORTICIACEAE OF NORTHERN CHINA

<正> 98 species of Corticiaceae s.l.are reported from Changbai shah forestreserve in Northern China.Phlebia pellucida Hjortst.& Ryv.is described as new.The newcombinations Amylosporomyces subasperisporus,Boidinia propingua,and B.peroxydata are pro-posed.The genus Boidinia is discussed and a key is given to accepted species.Many rarespecies are reported such as Amylocorticium laceratum,Ceraceomyces sulphurinus,Hyphodontiaaltaica,Laeticorticium ussuricum,Lobulicium occultum,Sistotrema athcloiides and Tubulicrinissceptiferus.The flora is boral and most of the species have a wide distribution in the Nor-thern coniferous zone.In a previous paper species of Polyporaceae were reported from Northern China(Ryvarden et al.,1986).Most of the species were collected during a short expedition tothe Changbai Shun forest reserve in the Jilin Province.This paper reports the species ofCorticiaceae (s.lato) from the same expedition.There are duplicates of all species bothin Oslo University Herbarium and the Herbarium of Mycologicum,Academia Sinica(HMAS)the Institute of Microbiology in Beijing.The knowledge of the Corticiaceae of China is veryfragmentary and many of the names indicated in previous reports are now replacedby othernames,and the identification of the collections in many cases are dubious.Thus,we havenot tried to establish how many of these species which previously have not been reportedfrom China.Such a list would be of little interest since very few has collected Corticiacritically in recent times,and the flora is still more or less unknown with regard to thisgroup of fungi.The following list must therefore be regarded as a first contribution tolist the Corticiaceae of China based on the same species concepts and names as currentlyused in Europe and North America,see Eriksson et al.(1976—84)Jiilich and Stalpers(1984),Gilbertson (1974).List of collections all from 11—17 Sept.1983.Nos.21315—21407/21696—21814.Jilin Prov.,Changbai Shah,Forest Reserve,Hangcong gou,750 m.a.s.l.Nos,21408—21603.JilinProv.,Changbai Shah,Forest Reserve,Huang Song Pu,1200 m.a.s.l.Nos.21619—21695.Jilin Prov.,Changbai Shun,Forest Reserve,Bai Shun Station,1100m.a.s.l.

A new wild banana species, M. chunii Hakkinen from Yunnan, China is described and illustrated based on observed morphological characteristics in the field. This extremely rare new species was only found in Tongbiguan Nature Reserve, Dehong District, West Yunnan. A key to M. chunii and related taxa is provided. In addition, critical notes regarding M. rubra Kurz identity are given.     

Report on the Hippolytidae Bate (sensu lato) from China seas

Thirty species belonging to 13 genera of three families in the Hippolytidae Bate, 1888(sensu lato) are reported in the present paper, including two new species and two newly recorded ones from the China seas. The two new species are named as Thinora leptochelus sp. nov. and Thor singularis sp. nov. Thinora leptochelus sp. nov. differs from the only knwon species of the genus, Thinora maldivensis(Borradaile, 1915), by the developed supraorbital tooth and the slender and cone-shaped chelae of the first 2 pereopods. Thor singularis sp. nov. can be dinstingershed from the other members of the genus Thor by the first 2 pereopods with epipods. The two newly recorded species from China seas are Eualus kikuchii Miyake & Hayashi, 1967 and Heptacarpus commensalis Hayashi, 1979.
