In the vicinity of Kyoto City, 4 species of freshwater planarians, Dugesia japonica, Phagocata vivida, Phagocata kawakatsui and Bdellocephala brunnea, were found. D. japonica was most common in the stations both in the plain and the mountainous districts (below the altitude of about 950 m). P. vivida was rather common in the cold-water stations within the altitude range from about 120 to 950 m or more. P. kawakatsui was found only in a spring-fed stream in Kameoka City (Asahi-cho; the type locality of this species) and in a shallow well at Saga-tenryuji-chd in Kyoto City. A small population of B. brunnea was found in a large spring-fed stream at Nishioji-sichijo in Kyoto City (the southernmost locality of this species). This station is well known to biologists as the locality of the sexual race of D. japonica (the Nishioji stock). The type of the vertical distribution in the area surveyed is shown as J-JV-V (J; D japonica; V: P vivida). The 2 species of true lake-dwelling tri-clads, BdellocepEala annandalci and Dendrocoelopsis? sp. of Lake Biwa-ko, were recorded from the muddy bottom (35 to 50 m or more in depth) of the middle and northern parts of Lake Biwa-ko.

The occurrence in Hong Kong of a freshwater planarian species Dugesia japonica Ichikawa et Kawakatsu, 1964, is reported. A taxonomic revision of every known record of Dugesia in China is also given. Stimpson\’s (1857) 3 uncertain species established from Hong Kong and the E China Sea area (Planaria sinensis, P. cinerea and P. badia) seem to be identical with D. japonica, the commonest and polymorphic form distributed widely in the NE area of the Far East including the Japanese Islands. It is suggested that it would be better to suppress the names of Stimpson\’s species as nomina oblita than to rename the now well-established D. japonica.

{Dugesia japonica Ichikawa et Kawakatsu, 1964, is a common and polymorphic species of freshwater planarian distributed widely in the Far East. In 1976 the geographic populations were separated into 2 subspecies (D.j.japonica and D.j. ryukyuensis). The taxonomy of this species is reconsidered once again from the morphological, anatomical, histological, and karyological viewpoints. From the result of these studies, D.j. ryukyuensis is elevated to the rank of species: D. ryukyuensis Kawakatsu, 1976. D. japonica (n = 8}

The new species Dugesia notogaea Sluys \& Kawakatsu, sp. n. is described from Queensland, Australia, representing the first record of the genus Dugesia for that continent. A phylogenetic analysis of the 68 species of Dugesia resulted in the discovery of a new apomorphy for the genus, and a cladogram showing two major phyletic groups. The distributional range of one group has a western accent, whereas that of the other group has an eastern emphasis; the ranges of these two groups overlap in Africa and the Mediterranean region. We attempt to determine the ancestral area for both the Dugesiidae and Dugesia. A scenario for the historical biogeography of the genus Dugesia is discussed. In this scenario it is presumed that the geological history of the Australasian region enabled Dugesia\’s from southeast Asia to colonize northern Australia.
