New replacement names are proposed for seven species of the subfamily Typhlocybinae; one new synonym is recognized in the family Delphacidae. The following changes are proposed: Empoasca (Empoasca) angustata nom.nov. for Empoasca angusta Linnavuori & DeLong (not Dworakowska); Empoasca (Empoasca) chilensis nom.nov. for Empoasca diversa Linnavuori & DeLong (not Vilbaste); Austroasca verdensis nom.nov. for Empoasca artemisiae Lindberg (not Lethierry); Kropka vidanoi Dworakowska for Erythroneura unipunctata Dlabola (not Cerutti); Zyginella vietnamica nom. nov. for Zyginella melichari Dworakowska (not Kirkaldy); Eupteryx (Eupteryx) dlabolai nom. nov. for Eupteryx octonotata Dlabola (not Hardy); Baaora ahmedi nom. nov. for Baaora spinosa (Ahmed) (not Beamer); Paradelphacodes insolitus Dmitriev is synonymized with Paradelphacodes gvosdevi (Mitjaev), syn. nov.  相似文献

测定了中国Singhardina亚属15个代表种的核糖体28S基因D2区和线粒体16S基因、COI基因部分序列,分别采用最大简约法、最大似然法和贝叶斯法构建分子系统树。系统发育树显示了相似的拓扑结构,明晰了各分支间的关系。首次探讨了中国Singhardina亚属4个种团间的系统发育关系。结果显示,Singhardina亚属构成了1个独立支系,代表1个单系群。本研究首次提出种团Eurhadina(Singhardina)rubra,并推测该种团可能是Singhardina亚属中最原始的种团。种团Eurhadina(Singhardina)robusta和E.(Singhardina)mamata为姐妹群。种团E.(Singhardina)vittata不能从种团E.(Singhardina)punjabensis中分出得到了分子数据的支持。  相似文献

The tea green leafhopper, Empoasca onukiiMatsuda (Hemiptera: Cicadellidae: Typhlocybinae), is a serious pest of tea plants in East Asia. Previous work has shown that two tea germplasms, Cd19 and Cd289, sustain less hopperburn damage by E. onukii than does Camellia sinensis (L.) O. Kuntze cv. ‘Yabukita’ (Theaceae), and E. onukii excretes less honeydew on these germplasms than on the susceptible Yabukita. This study investigated the feeding behavior of E. onukii with a direct current electropenetrograph (DC EPG) to compare feeding behaviors, including ingestion, on resistant tea germplasms and Yabukita. Feeding behaviors on the resistant germplasms were significantly restricted, with few bouts of active ingestion of short duration and long periods of non‐probing, whereas E. onukii engaged in active ingestion of long duration many times on the susceptible cv. Yabukita. The tea germplasms, Cd19 and Cd289, therefore showed strong resistance to E. onukii. Furthermore, the shape of puncture holes left after probing was compared between the susceptible Yabukita and the resistant germplasms. The puncture holes on Cd19 and Cd289 were indistinct in shape and closed compared with those on Yabukita.  相似文献

This study identifies 'centers of endemism' for typhlocybine leafhoppers in China, revealing diversity patterns and congruence of patterns between total species rich- ness and endemism. Distribution patterns of 774 Typhlocybinae (607 described and 167 undescribed species) were mapped on a 1.5° × 1.5° latitude/longitude grid. Total species richness, endemic species richness and weighted endemism richness were calculated for each grid cell. Grid cells within the top 5% highest values of weighted endemism richness were considered as 'centers of endemism'. Diversity patterns by latitude and altitude were obtained through calculating the gradient richness. A congruence of diversity patterns between total species richness and endemism was confirmed using correlation analysis. To investigate the bioclimatic factors (19 variables) contributing to the congruence be- tween total species richness and endemism, we compared the factor's difference between non-endemic and endemic species using the Kruskal-Wallis test. Eleven centers of en- demism, roughly delineated by mountain ranges, were identified in central and southern China, including the south Yunnan, Hengduan Mountains, Qinling Mountains, Hainan Is- land, Taiwan Island and six mountain areas located in western Sichuan, northwest Fujian, southeast Guizhou, southeast Hunan, central and western Guangdong, and north Zhejiang. Total species richness and endemic species richness decreased with increased latitude and had a consistent unimodal response to altitude. The proportions of endemism decreased with increased latitude and increased with rising altitude. Diversity patterns between total species richness and endemism were highly consistent, and 'Precipitation of Coldest Pe- riod' and 'Temperature of Coldest Period' may contribute to the congruence of pattern. Migration ability may play a role in the relationship of endemism and species richness; climate, environment factors and important geologic isolation events can also play crucial effect  相似文献
