Research output: Contribution to journalArticlespeer-review


The occurrence in Hong Kong of a freshwater planarian species Dugesia japonica Ichikawa et Kawakatsu, 1964, is reported in the present paper. A taxonomic revision of every known record of Dugesia species in China is also given. Stimpson's (1857) three uncertain species established from Hong Kong and the East China Sea area (Planaria sinensis, Planaria cinerea and Planaria badia) seem to be identical with Dugesia japonica, the commonest and polymorphic form distributed widely in the northeastern area of the Far East including the Japanese Islands. The senior author's opinion is that it would be better to suppress the names of Stimpson's species as nomina oblita than to rename the now well-established Dugesia japonica.
