中国拟天牛科部分类群分类(鞘翅目拟步甲总科)-动物学专业论文.docx

摘要拟天牛科Oedemeridae是中国尚未涉足的1个拟步甲总科Tenebrionoidae类群，全球已知约100属1500种，广泛分布于除南极洲以外的世界各大陆，尤以热带，亚热带种类丰富。该科中国已知22属118种（亚种），分类全由外国学者完成，为此，开展中国拟天牛科分类研究在我国具有开拓性意义。本文分总论和各论两部分。总论部分介绍了拟天牛科Oedemeridae的国内外研究进展、形态特征及术语、研究材料与方法、分类系统与系统发育、地理分布和生物学及经济意义等；各论部分记述我国部分拟天牛科1亚科3族8属63种，编写了分亚科、属、种检索表，列出了科、属、种的文献引证、同异名目录、标本信息和分布地等，并附有形态特征图和整体照片以便物种的辨识。研究发现1新种（二斑双距拟天牛Diplectrusbistigmaeus sp.nov.）和3中国新纪录种分别是栗颈双距拟天牛Diplectrus castaneicollis?vihla（云南），布伦短毛拟天牛Nacerdes(Xanthocgroa)brenadelli?vihla,1987（西藏）和二色短毛拟天牛N.(X.) mimoncomeroides?vihla,1998（西藏）。新种模式标本和中国新纪录标本保存在河北大学博物馆。AbstractThefamilyOedemeridaewaserectedbyLatreille(1810),anditbelongstothe superfamilyTenebrionoidae,thecategoryHetercomera,thesuborderPolyphaga,theorder Coleoptera.Untilnow,about1500specieshavebeenknownallthroughtheworld.The speciesofthefamilydistributeoneverycontinent,exceptforAntarctica,especiallytropical andsubtropicalareas.InChina,22generaand118species(subspecies)havebeendiscovered.
