Abstract

In this paper, a new species of Polycelis of the family Planariidae from China is described. Mature individuals have 80 –140 eyespots; the testes are well-developed and most of them occupy the entire dorso-ventral space; the penis is a long cone with well-developed mus-culature; the boundary between the penis bulb and penis papilla is vague and the bulbar cavity is not observed; the bursal canal is surrounded by a well-developed coat of circular muscles, and a thin layer of longitudinal muscles. The karyotype shows a diploid comple-ment of 38 chromosomes, with the formula 2n = 38 = 24m + 14sm.
