A palynotaxonomic study of the genus Filipendula （Rosaceae）

Pollen grains from 15 species （18 taxa） of the genus Filipendula were examined with light and scanning electron microscopy. It was revealed that the pollen grains are isopolar, tricolporate, with scabrate or scabrate-microechinate surface. The pollen morphology was compared with the conventional classification systems of the genus by different authors, and supported Shimizu＇s system （1961）, in which the genus was divided into three subgenera. The monotypic subgen. Hypogyna is characterized by pollen lacking fastigium and thickened costae colpi. The other monotypic subgen. Filipendula differs from others by pollen having larger grain, larger pore size, longitudinally elliptic fastigium and thickened costae colpi. The largest subgen. Ulmaria is distinguished by pollen having rounded or latitudinally elliptic fastigium and thickened costae colpi. Sectional classification was not supported by the pollen morphology due to insufficient variability. Key words Filipendula, palynology, systematics.     

怀头鲇成熟卵膜表面扫描电镜观察

The surface ultrastructure of mature egg chorion of the tamed northern sheatfish Silurus soldatovi in Hei- longjiang river was investigated by scanning electron microscopy. The outermost layer was composed of a thin lamella of a jelly coat. The surface of ielly coat was characterized by overlapping net-like fibrillar lamellae, many clefts with bridges and pores. The pore canals were 0.25 μm in diameter. The pore density was about 0.7 - 1.0/μm^-2. The pores on the surface of jelly coart were distributed uniformly. Mature eggs of sheatfish possessed a funnel-shaped micropyle in the animal polar region. The micropylar region was about 0.04 mm^2 area in diameter with 3 - 8 ridges in radial arrangement. Fertilized eggs in which jelly coats were removed mechanically presented no adhesiveness and exhibited inlays of irregular granules on their surface [Acta Zoologica Sinica 51 （5）： 940-946, 2005].     

A New Species of the Gekko japonicus Group(Squamata: Gekkonidae) from Southwest China

A new species of the Gekko(Squa ma ta:Gekkonidae)is described from the border of Sichuan and Yunnan Province,southwest China,based on distinct morphological and molecular features.Gekko jinjiangensis sp.nov.is distinguished from congeners by a combination of the following characters:size small(SVL 50.2–61.6 mm,n=13);nares in contact with rostral;interorbital scales between anterior corners of the eyes 20–24;ventral scales between mental and cloacal slit 146–169;midbody scale rows 111–149;ventral scale rows 31–47;subdigital lamellae on first toe 8–11,on fourth toe 11–15;no webbing in the fingers and toes;with tubercles on uapper surface of fore and hind limbs;precloacal pores 4–5 in males;postcloacal unilateral tubercles 1–2;dorsal surface of body with 8–9 large greyish brown markings between nape and sacrum.In molecular analyses,the new species is sister to G.scabridus,but separated from them by approximately 9.9%–12.2%in genetic divergence as shown by a fragment of the partial mitochondrial ND2 gene.The new species is the highest Gekko with elevation range from 2000 to 2476 m.Further surveys are recommended to better understand the occurrence and population status of the new species.     

A new species of the genus Leptolalax(Anura:Megophryidae) from southern Vietnam

We describe a new species of megophryid frog from Phu Yen Province in southern Vietnam. Leptolalax macrops sp. nov. is distinguished from its congeners by a combination of the following morphological attributes:(1) body size medium(SVL 28.0–29.3 mm in three adult males, 30.3 mm in single adult female);(2) supra-axillary glands present, creamy white; ventrolateral glands indistinct;(3) tympanum externally distinct;(4) dorsal skin roughly granular with larger tubercles, dermal ridges on dorsum absent;(5) rudimentary webbing present between fingers Ⅰ–Ⅱ and Ⅱ–Ⅲ; rudimentary webbing between all toes; fingers and toes without dermal fringes;(6) in life ventral surface greyish-violet with white speckling;(7) supratympanic fold distinct, dark brown in life;(8) iris bicolored, typically golden in upper half, fading to golden green in lower half;(9) tibia short(TbL/SVL 0.44–0.45 in males); and(10) eyes large and protuberant(ED/SVL 0.15–0.16 in males).From all congeners for which comparable sequences are available, the new species differs markedly in the 16 S rRNA mitochondrial gene sequence(P-distance5.7%). The new species is currently known only from montane evergreen tropical forests of Song Hinh District, Phu Yen Province, and M'Drak District of Dak Lak Province at elevations of 470–630 m a.s.l.. We suggest the new species should be considered as Data Deficient following the IUCN's Red List categories. We also report a previously unknown Leptolalax mt DNA lineage from an evergreen tropical forest in the Hoa Thinh District of Phu Yen Province,which may also represent an undescribed species.     

SPECIES DIVERSITY AND COMMUNITY STRUCTURE OF SUCKING LICE IN YUNNAN, CHINA

On the basis of investigating 9 counties (towns) in Yunnan Province of China, the species diversity and community structure of sucking lice on the body surface of small mammal hosts are studied in the paper. Species richness (S) is used to stand for the species diversity. The calculation of community diversity index and evenness are based on Shannon-Wiener‘s method. 2745 small mammals captured from the investigated sites belong to 10 families, 25 genera and 41 species in 5 orders (Rodentia, Insectivora, Scandentia, Logomorpha and Carnivora) while 18165 individuals of sucking lice collected from the body surface of the small mammal hosts are identified into 4 families, 6 genera and 22 species. The species of sucking lice are much less than the species of their hosts. Most species of small mammals have their fixed sucking lice on their body surface. One species of small mammals usually have few species of sucking lice (1 to 4 species). The close species of the hosts in the taxonomy are found to have the same or similar dominant species of sucking lice on their body surface. The results reveal that the species diversity of sucking lice on small mammals is very low with a very simple community structure. The results also imply there may be a close co-evolution relationship between the lice and the hosts.

Two new species of <Emphasis Type="Italic">Coltricia</Emphasis> (Hymenochaetaceae,Basidiomycota) from southern China based on evidence from morphology and DNA sequence data

Two new species of Coltricia, C. austrosinensis and C. minima, are described from southern China on the basis of morphological characters and molecular evidence. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions indicated that the two new species were nested within the Coltricia clade in Hymenochaetales. Coltricia austrosinensis is characterized by centrally stipitate basidiocarps, lobed pileal margin, distinctly swollen stipe tip, cinnamon pore surface, large pores (1–3 per mm), and broadly ellipsoid basidiospores measuring 8–10?×?5.5–6.5 μm, with a distribution to date in subtropical China. Coltricia minima is characterized by tiny, centrally stipitate basidiocarps, entire pileal margin, uniform stipe, pileus bearing distinct concentric zones and pore surface dark greyish blue when fresh, small pores (3–4 per mm), narrow tramal hyphae (3.5–4 μm), and broadly ellipsoid to subglobose basidiospores measuring 6–7?×?4–5 μm, and occur in mixed tropical forests.

Morphological and molecular evidences for a new species of Lignosus (Polyporales, Basidiomycota) from tropical China

Lignosus hainanensis sp. nov., is described and illustrated on the basis of collections originating from tropical forest in Hainan Province, southern China. Both the morphology and phylogeny support this new species. It is characterized by its centrally stipitate basidiocarps arising from a distinct sclerotium, yellowish brown to cinnamon-brown pileal surface, cream to cream-buff pore surface, trimitic hyphal system with clamped generative hyphae, and oblong ellipsoid to cylindrical basidiospores. Lignosus hainanensis may be confused with L. rhinocerus, also occurring in southern China, but L. rhinocerus can be distinguished by its smaller pores (6–8 per mm) and smaller and distinctly broadly ellipsoid basidiospores (4–5 × 2.8–3 μm).     

Changbai wood-rotting fungi 16. A new species of <Emphasis Type="Italic">Fomitopsis</Emphasis> (Fomitopsidaceae)

Fomitopsis niveomarginata sp. nov. is described and illustrated from specimens originating from Changbaishan Nature Reserve, Jilin Province, northeastern China. It is characterized by annual to perennial, sessile to effused-reflexed basidocarps, with a cream-colored azonate and corky context, a yellowish brown and shining pore surface, and small, oblong-ellipsoid basidiospores. The new species is similar to Fomitella rhodophaea that has a concentrically sulcate and zoned pileal surface, smaller pores, and slightly wider basidiospores; furthermore, the latter occurs mainly in the tropical areas. Phylogenetically, the new species forms a well-supported, terminal monophyletic clade, distinct from other sampled Fomitopsis species and Fomitella rhodophaea. An identification key to the Chinese species of Fomitopsis is provided.
