Three new species of Hagnagora Druce, 1885 (Lepidoptera,Geometridae, Larentiinae) from Ecuador and Costa Rica and a concise revision of the genus

Three new Hagnagora Druce species (Geometridae, Larentiinae) are described: Hagnagora richardi Brehm, sp. n. from Ecuador, Hagnagora hedwigae Brehm, sp. n. from Ecuador, and Hagnagora mirandahenrichae Brehm, sp. n. from Costa Rica. A checklist of taxa assigned to Hagnagora is provided. Hagnagora is provisionally divided into six clades: the anicata clade (6 species), the buckleyi clade (3 species), the croceitincta clade (3 species), the ephestris clade (3 species), the mortipax clade (4 species) and Hagnagora subrosea (1 species). Two taxa are revived from synonymy: Hagnagora catagrammina Druce, stat. rev. and Hagnagora luteoradiata Thierry-Mieg, stat. rev. Two taxa are reinstated from subspecies to species level: Hagnagora acothysta Schaus, stat. rev. and Hagnagora jamaicensis Schaus, stat. rev. Four taxa are provisionally removed from Hagnagora: “Hagnagora” ignipennis, “Hagnagora” mesenata, “Hagnagora” vittata, and “Hagnagora” ceraria. After these changes, the genus Hagnagora now comprises 20 valid species.     

Bambusimukaria,a new bamboo-feeding leafhopper genus from China,with description of one new species (Hemiptera,Cicadellidae, Deltocephalinae,Mukariini)

A new genus and species, Bambusimukaria quinquepunctata gen. & sp. n., feeding on bamboo in Guizhou and Fujian, China, are described and illustrated. The characters of crown, frontoclypeus, forewing venations and male genitalia place the new genus in the tribe Mukariini.     

Taxonomic studies on the ant genus Ponera Latreille, 1804 (Hymenoptera,Formicidae), with the description of a new species from India

Four species of the ant genus Ponera Latreille, 1804, are recorded from India. The present study reports one new species Ponera sikkimensis sp. n., a divergent population of Ponera indica Bharti & Wachkoo, 2012 and one new record, Ponera paedericera Zhou, 2001 from India. An identification key and distributions for the four known Indian species of Ponera based on the worker caste are provided.     

Review of the South American leafhopper genus Parandanus (Hemiptera,Cicadellidae, Deltocephalinae)

The South American leafhopper genus Parandanus Linnavuori & DeLong (Deltocephalinae: Deltocephalini) is reviewed and four of its six species are illustrated and male genital characters are provided. Three new species from Peru, Parandanus longistylus Duan, sp. n., Parandanus nigricephalus Duan, sp. n. and Parandanus paracruciatus Duan, sp. n. are described. A key to species is also provided.     

The Stenopodainae (Hemiptera,Heteroptera) of Argentina

In Argentina, 10 genera and 33 species of Stenopodainae (Hemiptera: Reduviidae) have been recorded. Diagnoses of the genera, subgenera and species are given, and an illustrated key to genera is provided. Six species are new records for Argentina and an additional seven species represent new records for provinces.     

Cyphastrea kausti sp. n. (Cnidaria,Anthozoa, Scleractinia), a new species of reef coral from the Red Sea

A new scleractinian coral species, Cyphastrea kausti sp. n., is described from 13 specimens from the Red Sea. It is characterised by the presence of eight primary septa, unlike the other species of the genus, which have six, ten or 12 primary septa. The new species has morphological affinities with Cyphastrea microphthalma, from which it can be distinguished by the lower number of septa (on average eight instead of ten), and smaller calices and corallites. This species was observed in the northern and central Red Sea and appears to be absent from the southern Red Sea.     

hTNFR1在大肠杆菌中可溶性表达及纯化

将人源肿瘤坏死因子Ⅰ型受体（hTNFR1）基因克隆到pET-22b表达载体,成功构建了重组表达质粒pETH1,电转到Escherichia coli BL21（DE3）表达菌株中进行摇瓶发酵。实现了hTNFR1在大肠杆菌表达系统中的重组表达。但目的蛋白全部以包涵体的形式存在于沉淀中。为了提高hTNFR1在大肠杆菌中的可溶性表达,融合标签和分子伴侣两种策略被实施用于辅助hTNFR1的可溶性表达。结果表明,在hTNFR1的N端融合NusA标签后,hTNFR1的可溶性有一定提高;在NusA-hTNFR1基础上,过表达了7种分子伴侣,筛选出tig分子伴侣对hTNFR1蛋白可溶性表达有明显的促进作用,可溶性表达量约占总量的90％;对优化后的hTNFR1表达系统的可溶性蛋白进行Ni-NTA亲和层析纯化后,TEV蛋白酶酶切去除N端的NusA标签,结合Western blot分析鉴定,获得了大量高纯度的hTNFR1蛋白。研究结果为进一步研究hTNFR1的生理学活性及其在疾病治疗方面的应用奠定了良好基础。     

Revision of the planthopper genus Nycheuma Fennah (Hemiptera,Fulgoromorpha, Delphacidae)

Chinese species in the genus Nycheuma Fennah, 1964a (Hemiptera: Fulgoromorpha: Delphacidae: Delphacinae: Delphacini) are revised to include three species: Nycheuma cognatum (Muir, 1917), Nycheuma dimorpha (Matsumura, 1910) and Nycheuma nilotica Linnavuori, 1973. Nycheuma coctum Yang, 1989 is placed in synonymy with Nycheuma nilotica Linnavuori, 1973. Nycheuma dimorpha (Matsumura, 1910) is newly recorded from China. The generic characteristics are redefined. The main morphological characters, male genitalia of 3 species are described or redescribed and illustrated. A key to Chinese species in the genus is provided.
