Abstract
Material belonging to a new fossil genus and species of caddisfly, Pulchercylindratus punctatus n. gen., n. sp., was collected from the Daohugou locality (Middle Jurassic, Jiulongshan Formation; Inner Mongolia, China). The new species is assigned to the Hydrobiosidae according to subcylindrical shape of the 2nd segment of maxillary palp, the forked R1 (in the forewing, located near apex), and long anal cells (in the forewing). In addition, we propose to transfer the genus Juraphilopotamus Wang, Zhao & Ren 2009, known from the same locality, to the family Hydrobiosidae, based on the 1st and 2nd segments of the maxillary palp being cylindrical, shorter than the 3rd segment. A Middle Jurassic origination of family Hydrobiosidae can be established based on the new discovery. (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
文章标题中国中侏罗世一新种热蝇(毛翅目，水蝇科)
在中侏罗统九龙山组稻虎沟地区收集到一种新化石属pulcher圆柱虫punctatus n. gen.， n. sp.;内蒙古，中国)。根据上颌触须第2节的近圆柱形、叉形R1(位于前翼，近先端)和长肛细胞(位于前翼)，该新种归属于水生生物科。此外，我们建议将Juraphilopotamus属(Wang, Zhao &Ren 2009，来自同一地点，属于水生生物科，根据上颌触须的第一和第二节为圆柱形，比第三节短。在此基础上建立了中侏罗世水生生物科的起源。(©2013 WILEY-VCH Verlag GmbH &KGaA公司，Weinheim)
