Abstract

The subfamily Styloperlinae Illies is elevated to the rank of a family; the sister group is Peltoperlidae. A new subfamily of Peltoperlidae, Microperlinae, is established for Microperla Chu as the sister group of another subfamily, Peltoperlinae, which includes the other genera of the family. The superfamily Pteronarcyoidea is proposed for Pteronarcyidae, Styloperlidae and Peltoperlidae as the sister group of Perloidea. Cerconychia flectospina Wu and Nogiperla obtusispina Wu are transferred to Styloperla Wu. The egg, nymph and internal organs of Ceronychia livida Klapalek and the egg of C. brunnea Klapalek are described. The males and females of Cerconychia livida and C. brunnea and the males of Styloperla inae Chao and S. wui Chao are redescribed. Some external and internal features of many stonefly families are described to support the new system.
