日本に侵入したと推測されるカワリヌマエビ属を遺伝解析した結果、2つのクレードに分かれた。クレードIは日本在来亜種ミナミヌマエビと分布域が重なったが、クレードIIは日本と中国の両方にみられた。雄の外部形態からも、前者は在来、後者は外来種と判断された。日本の4地点では両クレードが混在し、外来種との交雑による遺伝子撹乱の可能性が示された。聞き取り結果と合わせると、日本のカワリヌマエビ属は中国の華中・華北地域、近年、兵庫県で発見された共生種ヒルミミズは華中地域から導入された可能性が高い。

The vertical distribution of freshwater planarians in the Nikko National Park in the northern part of the Kanto Region, Honshu (Lat. 36°40'N. to Lat. 37°00'N. and Long.139°10'E. to Long. 139°40'E.), is reported in the present paper. The park is characterized by volcanoes of the Nasu Volcanic Zone (Mt. Nantai, Mt. Shirane, etc.) and many volcanic lakes (Lake Chuzenji-ko, Lake Sai-no-umi, Lake Yu-no-umi, Lake Suga-numa, Lake Maru-numa, etc.). The highest peak, Mt. Shirane (2578M above sea level), is located at the central part of the park. The main river systems in the park are the Daiya (the upper tributary of the Kinu River), the Kinu, the Katashina (the upper part of the Tone River) and the Tadami (the upper part of the Aga River). The Oze-ga-hara Moor is situated at the north-western corner of the park (Lake Oze-numa is located at an elevation of 1665M). The survey of the Daiya River system (the altitude range from 530 to 2024M) was made in August-September, 1968. Three species of freshwater planarians, Dugesia japonica Ichikawa et Kawakatsu, Phagocata vivida (Ijima et Kaburaki) and Polycelis auriculata Ijima et Kaburaki, were found in the area surveyed. These three species were also recorded by Kaburaki (1922 a, b, 1936) and Ueno (1934) from the same river system. Kaburaki (op. cit.) recorded Bdellocephala brunnea Ijima et Kaburaki in the vicinity of Nikko City. In the Oze-ga-hara Moor, Ph. vivida was collected by Kawai (in litt. and 1954). As far as our present knowledge goes, the altitude of the upper limit of distribution of D. japonica (J) was about 1460 metres (the vicinity of Yumoto Hot Spring; cf. Kaburaki 1922 a, b). Ph. vivida (V) was recorded in the stations within the altitude range from about 950 to 1460 metres. Pol. auriculata (A) was recorded in the cold-water stations within the altitude range from about 930 to 1660 metres. The type of the vertical distribution in the park is shown as J-JVA-A. This type belongs to the original type J-JV-JVA-VA-A found in North Honshu (cf. Kawakatsu 1965, 1967).

The vertical distribution of freshwater planarians in the Tsugaru Peninsula in Aomori Prefecture (Lat. 40°40′N. to lat. 41°20′N. and Long, 140°10′E. to Long. 140°45′E.), the northernmost part of Honshu, was surveyed in 1966 and 1967. The Peninsula faces both the Tsugaru Straits and Mutsu Bay. The larger part of the Peninsula is covered with low mountains, of which the highest peak is 827 metres in height. The south-western part of the Peninsula is characterized by a level plain of cultivation. The main river system in the area surveyed is the Iwaki, which discharges into Juni-ko Lake and the Sea of Japan. In the area surveyed, six species of freshwater planarians, Dugesia japonica ICHIKAWA et KAWAKATSU, Phagocata vivida (IJIMA et KABURAKI), Phagocata teshirogii ICHIKAWA et KAWAKATSU, Polycelis auriculata IJIMA et KABURAKI, Polycelis sapporo (IJIMA et KABURAKI) and Dendrocoelopsis lacteus ICHIKAWA et OKUGAWA, were found. D. japonica was found to be common at the stations below the altitude of about 160 metres (inhabitable water temperature range, 8.0〜22.2℃). Ph. vivida was common at the stations below the altitude of about 380 metres (5.0〜21.8.C). Pol. auriculata was found in both the cold-water mountain streams and in some cold-water springs in the seaward district (0.5〜480m, 9.0〜14.0℃). Pol. sapporo, one of the common species in Hokkaido, was found at the stations below the altitude of about 120 metres (9.0〜21.8℃). It is an interesting fact that this species was rather common at the stations in the Tappizaki Cape district in the Tsugaru Peninsula. Small populations of Ph. teshirogii and Den. lacteus were found in the Tsugaru Peninsula. The type of the vertical distribution of the planarians in the area surveyed is (JSV)-JSVA-SVA-VA-A (J : D. japonica ; V : Ph. vivida ; S : Pol. sapporo ; A : Pol. auriculata). The geographical distribution of Pol. sapporo and Den. lacteus in Honshu were discussed. According to the best of our knowledge, Pol. sapporo has been recorded only from the northern side of the demarcation line drawn between the base of the Shimokita Peninsula and of the Tsugaru Peninsula (cf. KAWAKATSU 1965,p. 356,Fig. 5,1967,p. 125,Fig. 5). Den. lacteus has been recorded both from the Tsugaru Peninsula and in a little south of the southern demarcation line of distribution of Pol. sapporo (cf. KAWAKATSU, TESHIROGI, ISHIOKA & KASAHARA 1968).

In this paper, the vertical distribution of freshwater planarians in Hirosaki City, the Mt. Iwaki district (Lat. 40°30′N. to 40°50′N. and Long. 140°15′E. to 140°30′E.) and in the Juniko district (Lat. 40°32′N. to 40°35′N. and Long. 139°56′E. to 140°00′E.), all in the western part of Aomori Prefecture, Honshu, is reported. Mt. Iwaki (altitude, 1625 metres) is an extinct volcano of the Chokai Volcanic Zone and is situated at the south-western corner of the Tsugaru Plain. The Juniko district near the seashore of the Sea of Japan is characterized by many ponds or marshs. The main river systems in the area surveyed are the Iwaki and the Narusawa. The surveys were made in the summer of 1965 and in the spring and summer of 1966. In the area surveyed, five species of freshwater planarians, Dugesia japonica ICHIKAWA et KAWAKATSU, Phagocata vivida (IJIMA et KABURAKI), Phagocata teshirogii ICHIKAWA et KAWAKATSU, Polycelis auriculata IJIMA et KABURAKI and Bdellocephala brunnea IJIMA et KABURAKI, were found. D. japonica and Bd. brunnea were found to be common in many springs in Hirosaki City. Small populations of Ph. vivida and of Ph. teshirogii were also found in some of these springs. In the other districts of the area surveyed, D. japonica, Ph. vivida and Pol. auriculata were widely distributed. D. japonica was found in the stations below the altitude of about 525 metres (inhabitable water temperature range, 9.0〜25.0℃). Ph. vivida was found in the stations within the altitude range from about 40 to 620 metres (5.0〜15.0℃) above sea level. It is however clear that Ph. vivida is the species of nondominance in the western part of Aomori Prefecture. Pol. auriculata was common in the stations within the altitude range from about 200 to 1320 metres (5.0〜14.5℃). The type of the vertical distribution in the area surveyed is shown as J-JV-JVA-VA-A (J : D. japonica ; V : Ph. vivida ; A : Pol. auriculata). The geographical distribution and the breeding of Bd. brunnea were also discussed. According to the best of our knowledge, this species is distributed in Middle and North Honshu (from Kyoto City in the Kinki Region to the Shimokita Peninsula in the northernmost part of the Tohoku Region). In general, their active breeding season was from early February to mid-May. In one breeding period one worm laid one cocoon of 2 to 2.5mm in diametre. The hatching of the cocoons was observed within 23 to 37 days after the laying. In the laboratory cultures, 3 to 12 jveniles were released from one cocooon.
