We report the description of a new species of freshwater flatworm of the genus Dendrocoelum inhabiting the chemoautotrophic ecosystem of Movile Cave as well as several sulfidic wells in the nearby town of Mangalia, thus representing the first planarian species fully described from this extreme biotope. The species was also found in non-sulfidic wells localized in villages in the vicinity of the cave with a total of nine examined populations. Dendrocoelum obstinatum Stocchino \& Sluys, sp. nov. represents the first triclad being able to live in both sulfidic and non-sulfidic waters. Among the fauna of the Mangalia sulfidic ecosystem it is the only species found also outside of the current boundaries of the sulfidic aquifer. One possible explanation of this peculiar distribution is that the new species is limited to the old boundaries of the sulfidic aquifer. The latter became much smaller during the hydrogeological history of the region, so that D. obstinatum may be considered to be an indicator of the extension of the sulfidic aquifer in the past of the Mangalia region. In the context of a biogeographic discussion on the distribution of the genus Dendrocoelum we provide an annotated checklist of species reported from Romania.

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.

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.

This paper provides an overview of the current status of land planarian taxonomy. Familial and subfamilial definitions of Bipaliidae, Rhynchodemidae (Rhynchodeminae and Microplaninae) and Geoplanidae (Geoplaninae, Caenoplaninae and Pelmatoplaninae) are detailed in Systematic Account on the various taxa. Previous taxonomical studies of Taiwan land planarians are discussed. Based on material collected by Lue in 1982-1985, Lee in 2002, and Wu, Tsai and Lin in 2002, this preliminary study identified a total of 18 species: one species of Bipalium kewense Moseley, 1878 and 13 species of Diversibipalium from the family Bipaliidae, one species from the family Rhynchodemidae; two species from the subfamily Caenoplaninae, family Geoplanidae and one species of Australopacifica from the subfamily Caenoplaninae, family Geoplanidae. For each species, the material examined, description, distribution in Taiwan, remarks and specimen figures (if available) are provided in order to promote further studies on the Taiwanese land planarian fauna.

We explore and review the taxonomic distribution of morphological features that may be used as supporting apomorphies for the monophyletic status of various taxa in future, more comprehensive phylogenetic analyses of the dendrocoelid freshwater planarians and their close relatives. Characters examined are: (i) musculature of the pharynx; (ii) anatomy of the eye; (iii) distribution of testis follicles along the longitudinal axis of the body; (iv) epidermis of the body wall; (v) musculature of the ventral body wall; (vi) presence or absence of a penis papilla; (vii) position of the mouth opening; and (viii) anterior adhesive organ. A phylogenetic hypothesis, in the form of a character state tree, is developed. This hypothesis suggests that the Kenkiidae should be resurrected as a separate family, sharing a sistergroup relationship with the Dendrocoelidae. This sistergroup relationship is supported by the shared presence of an apomorphic anterior adhesive organ. Although the shape of the anterior adhesive organ, both within and between kenkiids and dendrocoelids, may differ considerably between species, they are all constructed according to the same principles. The monophyly of the Kenkiidae is supported by the presence of an apomorphic thickening of the marginal zone of the epidermis and presumably also by the presence of prepharyngeal testes. Within the Kenkiidae, the genus Macrocotyla should be considered as a junior synonym of Kenkia, which is characterized by the presence of an apomorphic Ôplanariid pharynx-type 2Õ. The monophyly of the Dendrocoelidae is suggested by the presence of a dendrocoelid type of pharynx. It is shown that multicellular eye cups with numerous photoreceptor cells are not restricted to the Dugesiidae and the Terricola but are also characteristic for the Dendrocoelidae; the phylogenetic implications of this character state distribution are discussed. It is pointed out that in planarians there may be a relationship between: (i) body size, the size of an eye cup and the number of its constituent pigment cells; and (ii) the size of an eye cup and the number of photoreceptor cells that it contains. Some tentative phylogenetic groups are suggested on the basis of the following presumed apomorphic characters: presence of transverse fibres in the ventral subepidermal musculature, presence of an extra longitudinal muscle layer in the outer pharynx musculature, a mouth opening that has shifted anteriad. It is suggested that the presumed monophyly of the genus Bdellocephala is supported by the apomorphic absence of a penis papilla, combined with a penial lumen provided with many plicae.

Collections of freshwater planarians made by two expeditions to the Kuril Islands and Kamchatka are described, thus providing the first comprehensive account of the occurrence of this group of animals in the Kuril Archipelago. The samples contained three species: Seidlia schmidti (Zabusov, 1916), S. elongata (Zabosova, 1929), and Phagocata sp. The new records for S. schmidti and S. elongata include asexual specimens that were identified on the basis of their eye arrangement. This study shows that freshwater planarian species that were already known to occur in Kamchatka and Japan have also colonized the Kuril Islands. Possible scenarios for dispersal into the Kuril Islands from two mainland source areas during the Last Glacial Maximum are discussed.

{Biogeographical and taxonomic information on the four non-indigenous freshwater planarians of Japan is reviewed, viz. Dugesia austroasiatica Kawakatsu, 1985, Girardia tigrina (Girard, 1850), G. dorotocephala (Woodworth, 1897), and Rhodax evelinae? Marcus, 1947. The occurrence of Girardia dorotocephala in Japan is unequivocally demonstrated. New karyological data are presented for populations of D. austroasiatica (chromosome complement: 2x=16
