沟伪叶甲属及其两个中国两新纪录种记述

A Review of Bothynogria and Descriptions of Two New Records Species of the Genus from China

【目的】记述沟伪叶甲属(Bothynogria Borchmann,1915),补充该属中国种类及分布情况。【方法】运用形态分类鉴定法,查阅相关文献,在体式解剖镜下进行标本鉴定与雄性外生殖器解剖。采用基恩士超景深三维显微摄像系统(Keynece VHX-5000)拍摄照片。【结果】鉴定出异色沟伪叶甲(Bothynogria bicolor (Kollar et Redtenbacher,1848))和印度沟伪叶甲(Bothynogria meghalayana Merkl,1990)为中国新纪录种。沟伪叶甲属已知5种分布于中国,对它们进行了详细的描述,提供了整体图、局部特征图及雄性外生殖器图。编制了世界沟伪叶甲属已知6种的分种检索表。【结论】沟伪叶甲属世界已知6种,在中国分布已知5种,分别为异色沟伪叶甲、齿沟伪叶甲(Bothynogria calcarata Borchmann,1915)、喜马沟伪叶甲(Bothynogria himalayana Borchmann,1936)、印度沟伪叶甲和红胸沟伪叶甲(Bothynogria ruficollis (Hope,1831))。

[Purposes]To record the system of the genus BothynogriaBorchmann,1915(Coleoptera:Tenebrionidae:Lagriinae)from China.[Methods]The traditional morphological classification based on morphological characters.Descriptions were made under a stereomicroscope(Olympus SZ61).Images were obtained using a Digital Microscopic System VHX-5000.The measurements and indices used throughout the descriptions were measured by the VHX-5000.[Findings]Bothynogriafrom China includes five species,of which Bothynogria bicolor(Kollar et Redtenbacher,1848)and Bothynogria meghalayana Merkl,1990 are two newly recorded from China.Photographs of the dorsal habitus,ventral view and illustrations of the male genitalia of those five species are provided.A key to the species of Bothynogriais given.[Conclusions]The genus Bothynogriaincludes six known species in the world,of which five species are from China.These five species are B.bicolor,Bothynogria calcarata Borchmann,1915,Bothynogria himalayana Borchmann,1936,B.meghalayana,and Bothynogria ruficollis(Hope,1831).
