属于石蚕新属和新种化石的材料，Pulchercylindratus punctatus n。将军，n. sp.，采自道虎沟地区（中侏罗世，九龙山组；中国内蒙古）。根据上颌须第二节的亚圆柱形形状、分叉的 R1（位于前翅，位于顶端附近）和长肛门细胞（位于前翅），该新种被划入 Hydrobiosidae。此外，基于上颌须的第一节和第二节是圆柱形的，比第三节短，我们建议将来自同一地点的 Juraphilopotamus Wang、Zhao & Ren 2009 转移到 Hydrobiosidae 科。根据这一新发现，可以确定 Hydrobiosidae 科的中侏罗世起源。
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.
