Playing hide-and-seek with the tiny dragonfly: DNA barcoding discriminates multiple lineages of <Emphasis Type="Italic">Nannophya pygmaea</Emphasis> in Asia

We examined the utility of DNA barcode data for assessing genetic diversity of the tiny dragonfly Nannophya pygmaea Rambur in Asia. Data analyses inferred from the barcode region of cytochrome oxidase subunit I (COI) were performed with Malaysian N. pygmaea, along with the existing COI haplotypes distributed in Asia. We applied four species delimitation analyses [automatic barcode gap discovery (ABGD), generalised mixed yule coalescent (GMYC), poisson tree processes maximum likelihood (PTP_ML) and poisson tree processes simple heuristic solutions (PTP_sh)] to investigate potential lineages in this geographically widespread species. Based on our dataset, we provisionally recognize four distinct lineages or operational taxonomic units of N. pygmaea, which were represented by the taxa from Japan/Korea, China/Laos/Taiwan, Malaysia and Vietnam, respectively. Phylogenetic analyses showed two well-supported assemblages of N. pygmaea: one restricted to the taxa from Malaysia and Vietnam; and the other covering all populations further north (i.e., China, Japan, Korea, Laos and Taiwan). An extraordinarily high degree of genetic distance (up to >12 %) was detected between these two assemblages—suggesting they represent two separate species.

金绒花天牛与金丝花天牛的鉴定及分布(鞘翅目,天牛科,花天牛亚科,花天牛族)(英文)

金丝花天牛Leptura aurosericans Fairmaire,1895广泛分布在中国南方与东南亚地区,而金绒花天牛Leptura auratopilosa(Matsushita,1931)仅分布于台湾岛。最近10年,国内在金绒花天牛与金丝花天牛的鉴定及分布记录方面出现了一些不一致的报道。为了澄清这些问题,在核对模式标本及检视系列标本(包括许多正在自然交配的成对标本)的基础上,重新描述了这两个种的形态特征,给出了这两个种的鉴别特征并提供了彩色照片,认为金绒花天牛是台湾特有种,目前在大陆尚未发现。     

Review of the genus Tylopus Jeekel, 1968, with descriptions of five new species from Thailand (Diplopoda, Polydesmida, Paradoxosomatidae)

The genus Tylopus currently contains 41 species, all keyed and mapped, including five new from northern Thailand: Tylopus bispinosussp. n., Tylopus grandissp. n., Tylopus extremussp. n., Tylopus veligersp. n. and Tylopus parajeekelisp. n. Species of Tylopus are predominantly forest-dwellers, especially in montane habitats where up to 9-10 species can coexist per faunule. We expect many more congeners to be discovered in future, in particular from poorly or relatively poorly prospected regions such as Laos (only two species recorded), Cambodia (no species yet), Vietnam (a few species), Myanmar (a few species) and southern China (one species only). Because the genus is so species-rich and as yet so poorly sampled, a phylogenetic analysis of Tylopus would be premature.

基于线粒体COI基因的桔小实蝇种群遗传分化研究

【目的】推测桔小实蝇Bactrocera dorsalis在中国的扩散路径和新发生地区的入侵来源。【方法】本研究测序获得来自中国、泰国、日本、老挝、孟加拉国和美国等地31个种群的192头桔小实蝇个体的COI序列（1 496 bp,占COI基因全长97.3%）,并以软件DnaSP 5.0, MEGA 6.0和Arlequin 3.5等完成各种群的遗传多样性、种群间的遗传分化以及单倍型分析。【结果】所测31个桔小实蝇种群总体表现出较高水平的核苷酸多样性（0.00663）和高水平的单倍型多样性（0.98069）。以F-统计法度量种群间遗传分化程度, 结果显示中国桔小实蝇地理种群间遗传分化较弱, 中国种群与泰国、日本、老挝、孟加拉国、美国种群间的遗传分化程度不同, 中国种群与美国种群及日本种群的遗传分化最大。而Mantel检验发现,中国、泰国、日本、老挝、孟加拉国和美国种群间的遗传分化与空间距离有关（R=0.670, P<0.0001）, 中国种群间的遗传分化不是地理隔离所造成的（R=0.038, P=0.534）。中国种群与泰国、日本、老挝、孟加拉国和美国种群间不存在共享单倍型。根据种群系统发育树,可将中国原发生地区种群划分为西南、东南两大分支。中性检验和错配分析结果均表明桔小实蝇曾存在大规模的扩张。【结论】桔小实蝇以东南地区和西南地区为源头向中国内陆扩散,其中广东、福建、广西和贵州种群为中国内陆种群较为有影响力的源头。根据遗传多样性、遗传分化、单倍型分析,推测新发生地区桔小实蝇的来源, 例如安徽合肥桔小实蝇种群主要来源于福建长乐、广东珠海和上海。

Two new genera of Nanophyidae with six desmomeres (Coleoptera, Curculionoidea)

A new genus Lyalia is described in Nanophyidae and three species are included in it: Lyalia curvatasp. n. (Vietnam), Lyalia robusta (Pic, 1921), comb. n. (from Nanophyes) (Java, Bali, Laos) and Lyalia albolineata (Pajni & Bhateja, 1982), comb. n. (from Ctenomerus) (India: Assam). Ctenomerus lagerstroemiae G. A. K. Marshall, 1923 is a syn. n. of Lyalia robusta. Thus, the genus Ctenomerus Schoenherr, 1843 is restricted to the Afrotropical Realm. Kantohiagen. n. is erected for Kantohia taiwana (Kantoh & Kojima, 2009) (from Shiva) (Taiwan). A key to the Nanophyinae genera with six desmomeres is presented.

鳜亚科SINIPERCINAE鱼类的分类整理和地理分布

鳜亚科鱼类仅产于东亚。通过对中国各地、日本和朝鲜标本的研究,本文把鳜亚科鱼类总结为鳜、长体鳜和少鳞鳜3属11种,还对过去一些种的异名作了讨论,提出了看法。 本亚科共有3属9种分布于中国,另两种少鳞鳜只见于日本和朝鲜,是日本和朝鲜地区的特有种。越南有3种记录(Mai,1978)。其中鳜鱼和斑鳜分布最北,是横跨东洋地区和古北区的两个广布种。其他各种皆集中分布于江、淮流域以南,主要在长江流域以南和红河流域以东,但台湾省无鳜类分布。长江流域以南低纬度的华南区是鳜亚科鱼类的分布中心。     

Identifying Vulnerable Populations Using a Social Determinants of Health Framework: Analysis of National Survey Data across Six Asia-Pacific Countries

Background

In order to improve the health of the most vulnerable groups in society, the WHO called for research on the multiple and inter-linking factors shaping the social determinants of health (SDH). This paper analyses four key SDH (social cohesion, social inclusion, social empowerment and socioeconomic security) across six Asia-Pacific countries: Australia, Hong Kong, Japan, South Korea, Taiwan, and Thailand.

Methods

Population surveys were undertaken using a validated instrument in 2009-10, with sample sizes around 1000 in each country. The four SDH were analysed using multivariate binomial logistic regression to identify socio-demographic predictors in each country.

Results

Low socio-economic security was associated with low income in all six study countries and with poor subjective health in Japan, South Korea and Thailand and with being married or cohabiting in Australia and Hong Kong. Low social cohesion was associated with low income in all countries and with undertaking household duties in South Korea, Thailand and Taiwan. Low social inclusion was associated with low income in Australia, South Korea and Taiwan and with poor subjective health in Australia, Japan and South Korea. Older people had lower social inclusion in Taiwan (50-59 years) and Hong Kong (retired), younger people in Japan and South Korea (20-29 years in both countries) and younger and middle-aged people in Australia. Low social empowerment was associated with low income in Australia, Thailand and Taiwan, with being aged 60 years or over in Australia, Hong Kong and South Korea, and over 50 years in Thailand.

Conclusions

This paper provides baseline measures for identifying where and how policy should be altered to improve the SDH. Furthermore, these data can be used for future policy evaluation to identify whether changes in policy have indeed improved the SDH, particularly for marginalised and vulnerable populations.     

New species, new records and new morphological characters of the genus Tillicera Spinola from China (Coleoptera, Cleridae, Clerinae)

Two new species of the genus Tillicera Spinola, 1841 from China are described and illustrated: Tillicera sensibilissp. n. from Yunnan (also from Myanmar, Thailand and Laos) and Tillicera weniisp. n. from Taiwan. Tillicera bibalteata Gorham, 1892, Tillicera hirsuta (Pic, 1926) and Tillicera michaeli Gerstmeier & Bernhard, 2010 are newly recorded from China. Tillicera auratofasciata (Pic, 1927) is newly recorded in some provinces of China. A key to species of the genus from China is provided. Relationships between species are discussed with emphasis on characters of male phallus, female internal reproductive organs and pit-like sensilla in male terminal antennomere, which is discovered in Tillicera for the first time. The present generic definition of Tillicera is discussed as well. Photos of terminalia of the previously known species are also provided for comparison.     

Identification of Fasciola flukes in Thailand based on their spermatogenesis and nuclear ribosomal DNA, and their intraspecific relationships based on mitochondrial DNA

We analyzed 147 Fasciola flukes obtained from cattle in Thailand based on their spermatogenetic ability, and nuclear ribosomal internal transcribed spacer 1 (ITS1) and mitochondrial nicotiamide adenine dinucleotide dehydrogenase subunit 1 (ND1) genes as molecular markers. One hundred twenty-eight flukes, which had abundant sperm in their seminal vesicles (spermic) and showed the PCR-RFLP pattern of F. gigantica in the ITS1, were accurately identified as F. gigantica. The other 19 flukes that had no sperm in their seminal vesicles were aspermic Fasciola sp. with the RFLP patterns identical to that of F. gigantica. Twenty-nine ND1 haplotypes (Fg-ND1-Thai 2-30) were distinguished in the 128 F. gigantica flukes and were divided into haplotypes unique to Thailand and those common to other countries, suggesting the possibility that ancestral haplotypes were introduced into Thailand. Three haplotypes (Fg-ND1-Thai 7, 9 and 27) appeared to be the major haplotypes found in F. gigantica from Thailand. Only one haplotype (Fg-ND1-Thai 1) was found in the 19 aspermic Fasciola sp. flukes obtained from geographical regions, and the nucleotide sequence of Fg-ND1-Thai 1 was identical to that of the aspermic Fasciola sp. from Japan, Korea, China, Vietnam and Myanmar, suggesting that they were descendants with a common provenance and expanded to these countries in the relatively recent past.     

Six new species of Agrilus Curtis, 1825 (Coleoptera,Buprestidae, Agrilinae) from the Oriental Region related to the emerald ash borer, A. planipennis Fairmaire, 1888 and synonymy of Sarawakita Obenberger, 1924
