文章摘要：Polypedilum Kieffer, 1912, has a cosmopolitan distribution and includes about 500 species (Cranston et al. 2016). It is a heterogeneous group, and the larvae occur in almost all lentic and lotic waters, except at high altitude and latitude. The male imagines of the genus can be recognized by the combination of deeply bifid pulvilli and abdominal segment VIII constricted basally giving it a triangular appearance. The delimitation of subordinate groups within Polypedilum is difficult and problematic since the diagnoses of different stages are not always consistent. Sæther et al. (2010) divided Polypedilum into eight subgenera: Polypedilum (s. str.); P. (Pentapedilum) Kieffer, 1913; P. (Tripedilum) Kieffer, 1921; P. (Kribionympha) Kieffer, 1921; P. (Tripodura) Townes, 1945; P. (Uresipedilum) Oyewo & Sæther, 1998; P. (Cerobregma) Sæther & Sundal, 1999; and P. (Probolum) Andersen & Sæther, 2010. Cranston et al. (2016) treated Tripedilum to as a junior synonym of Polypedilum (s. str.). In the last decade, 40 new species of the genus Polypedilum have been described in China. To date, 82 species of Polypedilum assigned to six subgenera have been recorded in China, including six in P. (Cerobregma), eight in P. (Pentapedilum), 24 in Polypedilum (s. str.), one in P. (Probolum), 27 in P. (Tripodura), and 16 in P. (Uresipedilum) (Wang 2000; Wang et al. 2005; Lin et al. 2013; Qi et al. 2014; Zhang & Wang 2004, 2005a, 2005b, 2006, 2007a, 2007b, 2008; Zhang et al. 2015; Qi et al. 2016). In this contribution, two new species of Polypedilum (s. str.) with the anal point characteristically constricted distally are described based on male imagines.
