Melanconis-like fungi are distributed in several families of Diaporthales, mainly Juglanconidaceae, Melanconidaceae, Melanconiellaceae and Pseudomelanconidaceae. A new Melanconis-like genus of Pseudomelanconidaceae was discovered on branches of Chinese chestnut (Castanea mollissima) in southern China, which was confirmed by both morphology and phylogenetic analysis of combined ITS, LSU, tef1a and rpb2 sequences. The new genus Micromelanconis is characterized by two types of conidia from natural substrate and manual media of PDA, respectively. Conidia from Chinese chestnut branches are pale brown, ellipsoid, multiguttulate, aseptate with hyaline sheath. While conidia from PDA plates are pale brown, long dumbbell-shaped, narrow at the middle and wide at both ends, multiguttulate, aseptate, and also with hyaline sheath. All Pseudomelanconidaceae species were only reported on tree branches in China until now. More interesting taxa may be discovered if detailed surveys on tree-inhabiting fungi are carried out in East Asia in the future.

Abstract In this study, we present a taxonomic review of a rarely collected subfamily of lace bugs (Vianaidinae: Tingidae: Heteroptera), including the description of nine new species and one new genus, and a phylogenetic analysis targeting its internal relationships. Anommatocoris araguanus sp. nov., A. knudsoni sp. nov., A. schuhi sp. nov., A. serratus sp. nov., A. sucreanus sp. nov., Thaumamannia insolita sp. nov. and T. urucuana sp. nov. are proposed, in addition to the new genus Henryvianaida gen. nov. with its two macropterous species, H. colombiensis sp. nov. and H. machupicchuensis sp. nov. The monophyly of all vianaidine genera is recovered and their synapomorphies are highlighted. Comments on fossil forms and insights on the future of Vianaidinae taxonomy and systematics are also included.

A new genus of Sycophaginae (Hymenoptera: Agaonidae), Sycidiphaga Liu, Rasplus & Huang n. gen., is described with a single new species, S. cyrtophyllae Liu, Rasplus & Huang n. sp. This species was discovered in Yun Nan and Gui Zhou, China and is associated with Ficus cyrtophylla (Moraceae, Ficus, subgenus Sycidium). The new taxon is readily distinguished from other genera of Sycophaginae by: 1) the presence of a conspicuous interantennal blade-like projection that extends well above the level of the toruli; 2) an inflated parastigma surrounded by a slight infuscation of the wing membrane; 3) the presence of a long and conspicuous median sulcus on the male pronotum; and 4) the presence of dense and long pilosity on the wings. Illustrations and a diagnosis and description of Sycidiphaga are provided, as is a key to the world genera of Sycophaginae. The phylogenetic position of Sycidiphaga was demonstrated through sequencing four gene regions of COI, Cyt b, 28s D3-D5 and EF-1α genes and conducting a phylogenetic analysis of available sequences for the subfamily. Sycidiphaga cannot be placed with confidence within Sycophaginae but several discussed characters suggest a close relationship with Idarnes Walker and Sycophaga Westwood.

An allergic reaction to mosquitoes can result in severe or abnormal local or systemic reactions such as anaphylaxis, angioedema, and general urticarial or wheezing. The aim of this review is to provide information on mosquito saliva allergens that can support the production of highly specific recombinant saliva allergens. In particular, candidate allergens of mosquitoes that are well suited to the ecology of mosquitoes that occur mainly in East Asia will be identified and introduced. By doing so, the diagnosis and treatment of patients with severe sensitivity to mosquito allergy will be improved by predicting the characteristics of East Asian mosquito allergy, presenting the future direction of production of recombinant allergens, and understanding the difference between East and West.

Novel Agent

A novel Borrelia species, Candidatus Borrelia javanense, was found in ectoparasite ticks, Amblyomma javanense, from Manis javanica pangolins seized in anti-smuggling operations in southern China. Overall, 12 tick samples in 227 (overall prevalence 5.3%) were positive for Candidatus B. javanense, 9 (5.1%) in 176 males, and 3 (5.9%) in 51 females. The phylogenetic analysis, based on the 16S rRNA gene and the flagellin gene sequences of the Borrelia sp., exhibited strong evidence that Candidatus B. javanense did not belong to the Lyme disease Borrelia group and the relapsing fever Borrelia group but another lineage of Borrelia. The discovery of the novel Borrelia species suggests that A. javanense may be the transmit vector, and the M. javanica pangolins should be considered a possible origin reservoir in the natural circulation of these new pathogens. To our knowledge, this is the first identification of a novel Borrelia species agent in A. javanense from pangolins. Whether the novel agent is pathogenic to humans is unknown and needs further research.

Dna Sequence Data

The generic taxonomy of the Nothofagaceae is revised. We present a new phylogenetic analysis of morphological characters and map these characters onto a recently published phylogenetic tree obtained from DNA sequence data. Results of these and previous analyses strongly support the monophyly of four clades of Nothofagaceae that are currently treated as subgenera of Nothofagus. The four clades of Nothofagaceae are robust and well-supported, with deep stem divergences, have evolutionary equivalence with other genera of Fagales, and can be circumscribed with morphological characters. We argue that these morphological and molecular differences are sufficient for the four clades of Nothofagaceae to be recognised at the primary rank of genus, and that this classification will be more informative and efficient than the currently circumscribed Nothofagus with four subgenera.        Nothofagus is recircumscribed to include five species from southern South America, Lophozonia and Trisyngyne are reinstated, and the new genus Fuscospora is described. Fuscospora and Lophozonia, with six and seven species respectively, occur in New Zealand, southern South America and Australia. Trisyngyne comprises 25 species from New Caledonia, Papua New Guinea and Indonesia. New combinations are provided where necessary in each of these genera.

One of the key questions for understanding the future trajectory of regional order is whether or not China is trying to push the United States out of East Asia and build a China-dominated regional order. Some Western analysts accuse China of pursuing the Monroe Doctrine and excluding the United States from the region. This article argues that the Western discourse of China practicing the Monroe Doctrine is a misplaced characterization of China's behavior. Rather than having intention of pushing the United States out of East Asia and build a China-dominated regional order, China is pursuing a hedging strategy that aims at minimizing strategic risks, increasing freedom of action, diversifying strategic options, and shaping the U.S.' preferences and choices. This can be exemplified in five issue areas: China's ties with the Association of Southeast Asian Nations (ASEAN), the Shanghai Cooperation Organization (SCO) and China's foreign policy activism, China-Russia relations, the Conference on Interactions and Confidence-Building Measures in Asia (CICA) and the New Asian Security Concept, as well as China-U.S. relations. Beijing has explicitly acknowledged the U.S. predominance in the international system and reiterated its willingness to participate in and reform the existing system. It concludes by suggesting that, for a more peaceful future to emerge in East Asia, the United States and China, as an incumbent power and a rising power, will have to accommodate each other, and negotiate and renegotiate the boundaries of their relative power, as well as their respective roles in the future regional order where Beijing and Washington would learn to share responsibilities and leadership.

Names of Large Exotic Animals and the Urheimat of Japonic

Abstract This article argues that three words designating large tropical animals not endemic for Japan: kisa ‘elephant’, tora ‘tiger’, and wani ‘saltwater crocodile’ were borrowed into Japonic from Austroasiatic or Kradai languages. If so, this becomes another important piece of evidence for locating the Urheimat of the Japonic Language family in Southern China and/or Northern South-East Asia driving yet another nail into the coffin of the ‘Altaic’ theory. Since all these words are disyllabic, they also contribute to the reconstruction of the disyllabic words in Austroasiatic and Kradai. This is especially important in the case of Kradai, where in spite of the rather recent fall of the monosyllabic curtain, the idea about the ‘primordial’ nature of the monosyllabic structure is still enjoying considerable support.
