网翅蝗科四种蝗虫的RAPD多态性研究

运用RAPD技术对网翅蝗科Arcypteridae 4种蝗虫24个个体的基因组DNA进行了多态性分析.在试用的24条随机引物中,筛选出11条引物用于4种蝗虫的随机引物扩增,共得到128条清晰稳定的扩增片段,每条引物的扩增片段数为10～13条,片段长度在100～2 000bp之间.根据扩增出的RAPD图谱,用UPGMA和NJ法对Nei's 遗传距离作聚类分析,构建分子系统树.聚类结果显示:同属的物种首先聚在一起;网翅蝗科4种蝗虫分为两支,竹蝗属Ceracris Walker的贺氏竹蝗Ceracris hoffmanni Uvrov、黑翅竹蝗Ceracris fasciata fsaciata(Br.-W.)优先聚为一支,隆额网翅蝗Arcyptera coreana Shiraki和宽翅曲背蝗Pararcyptera microptera meridionalis(Ikonn)聚为另一支.基于RAPD图谱的分子系统树所展示的物种间亲缘关系与传统的形态分类结果基本一致,此结果表明RAPD在科下不同属间亲缘关系的研究方面具有一定的可行性.

Two new species of Simulium (Gomphostilbia) (Diptera, Simuliidae) from Peninsular Malaysia, with keys to Peninsular Malaysian members of the Simulium ceylonicum species-group

Two new species of black flies, Simulium (Gomphostilbia) roslihashimisp. n. and Simulium (Gomphostilbia) lurauensesp. n., are described on the basis of reared adult, pupal and larval specimens collected from Peninsular Malaysia. These two new species are placed in the ceylonicum species-group within the subgenus Gomphostilbia. Simulium (Gomphostilbia) roslihashimisp. n. is most distinctive with the male having almost entirely yellow antennae, and Simulium (Gomphostilbia) lurauensesp. n. is characterized in the female by having the elongate sensory vesicle and the yellowish-white hairs on the base of the costal vein and on the stem vein, in the male by the greater number of large upper-eye facets and the spindle-shaped hind basitarsi which are much narrower than the hind tibiae and femora and in the pupa by the small terminal hooks. Keys to species of the ceylonicum species-group reported from Peninsular Malaysia are provided for females, males, pupae and mature larvae.     

Two new species of the genus Chablisea Gauld et Dubois (Hymenoptera: Ichneumonidae: Pimplinae) from Vietnam

Two new species of the genus Chablisea Gauld et Dubois, 2006 are described from Vietnam based on ichneumonid material collected from 2002 to 2008. Chablisea condimenta sp. n. differs from other species of the genus by the absence of the second abscissa of hind wing vein Cu1, narrower hind femur (5.2 times as long as wide), and yellow subapical, lateral spots on metasomal tergites 2–5. Chablisea khuatdanglongi sp. n. is characterized by its face as high as wide, yellow with a median black stripe extending to a black transverse band at the base of the clypeus. One species, C. albifacialis (Kusigemati, 1984) is a new combination.

To be or not to be: postcubital vein in insects revealed by microtomography

To better understand insect evolution, fossils – mainly known by their wings – must be used as terminals in phylogenetic analyses. Such analyses are, however, rarely performed because of a lack of consensus on the homology of venation in insects. Researchers do not agree with the current concept on the exact number and identity of the main veins. Here, we confirm the presence, which has been in question since the early 20th century, of an independent main postcubital vein (PCu vein) between the cubital and anal veins (29 fossil and extant examined orders; > 85% of observed insects). The PCu vein corresponds to the so-called vein 1A or first anal vein. It is easily identified by the unique shape of its bulla. It may have several branches and be partially fused with the cubital and anal veins. Once the PCu vein was identified, we reconsidered as an example the particular case of the Phasmatodea, showing that extant stick insects have a unique venation among insects, with a reduced median vein and a simple cubital vein adjacent or fused to the PCu vein. This study is a new approach towards resolving wing vein homology issues, crucial for future large-scale phylogenetic analyses in insects combining extant and extinct taxa.
