中国毛眼小粪蝇属记述(双翅目,小粪蝇科,沼小粪蝇亚科)

Notes of the Genus Trachyopella Duda from China (Diptera,Sphaeroceridae,Limosininae) with New Records and New Distributions

[目的]调查中国毛眼小粪蝇区系,了解真实物种状况。[方法]用扫网和马氏网在山区采集标本,用比较形态学对中国毛眼小粪蝇属进行种类分类和鉴定。[结果]记录中国毛眼小粪蝇属5种,其中包括1中国新分布种和2东洋界新记录种。中国新纪录种:Trachyopella(T.)mitis Rohá?ek et Marshall,1986;东洋界新记录种:Trachyopella(T.)artivena Rohá?ek et Marshall,1986;Trachyopella(T.)lineafrons(Spuler,1925)。[结论]目前中国毛眼小粪蝇属种类少,物种多样性较低。

[Objective] To investigate species composition of the genus Trachyopella Duda from China for better knowledge of these species.[Method]The research used sweeping nets and Malaise traps to collect sphaeroceridae samples in the mountainous areas in China and uses morphology to identify and classify them.[Result]The paper includes 5 Trachyopella species from China,among which there is 1 Chinese new record and 2 Oriental new records.The Chinese new record:Trachyopella(T.)mitis Rohá?ek et Marshall,1986;The Oriental new record:Trachyopella(T.)artivena Rohá?ek et Marshall,1986;Trachyopella(T.)lineafrons(Spuler,1925).[Conclusion]Presently the number of Chinese Trachyopella species is small,and the Chinese Trachyopella diversity is not rich.
