Systematics and Biogeography of Chinese Bitterlings

1995 ~ 1996年，6名日本和6名中国学者在中国对中国苦味动物进行了系统学和生物地理学研究。1995年，我们和中国的研究人员一起去了上海市、浙江省、湖北省和云南省，在那里我们研究了分类、核型和收集样品进行DNA实验。我们还参观了武汉中国科学院水生生物研究所博物馆和昆明中国科学院动物研究所博物馆，在那里我们检查了来自中国许多地方的鱼标本。1996年，我们随中国调查人员前往上海市、辽宁、山东、湖北和浙江省，在那里进行了分类、核型研究，并采集了DNA实验样品。我们还与中国调查人员一起访问了天津自然博物馆和山东大学，在那里我们检查了来自山东省的模式标本。 ...更多信息 1995 ~ 1996年考察的结果表明：（1）日本特有种红Rhodeusatremius在浙江省发现。2)在中国首次发现了n=23的一个新种（上田等人，印刷中）。3)研究了Rhodeus lighti和Tanakia himantegus的Ag-NOR（上田等人，印刷中）。4)中国特有种光氏Rhodeus lighti和韩国特有种尾木Rhodeus uyekii是中国特有种中华Rhodeus sinensis（Akai and Arai，in press）的次异名。5)Acheilognathus damnanus包括两个种。6)在我国尚未见文献报道的披针叶Tanakia lanceolata（Arai et al.，1995年）。7)首次在上海市采集到Tanakia种。8)在中国首次发现了一种似乎在秋天产卵的小海龟。9)本文对9种中国种（包括亚种）、15种日本种（包括亚种）、1种朝鲜种和1种欧洲种的头感觉管和眶下骨进行了研究。一些种的成虫标本具有幼鱼特有的头状感觉通道，表明种化是由幼鱼的幼态形成的。少

Systematics and Biogeography of Chinese Bitterlings were studied by 6 Japanese and 6 Chinese investigators in China from 1995 to 1996. In 1995, we went to Shanghai City, Zhejiang, Hubei, and Yunnan Provinces with Chinese investigators, where we studied classification, karyotypes and collected samples for DNA experiments. We also visited the Museum of Institute of Hydrobiology, Academia Sinica, Wuhan and the Museum of Kunming Institute of Zoology, Academia Sinica, Kunming, where we examined specimens of bitterlings from many places of China. In 1996, we went to Shanghai City, Liaoning, Shandong, Hubei and Zhejiang Provinces with Chinese investigators, where we studied classification, karyotypes and collected samples for DNA experiments. We also visited the Tianjin Natural History Museum, Tianjin and the Shandong University, Jinan with Chinese investigators, where we examined the type specimen of Pseudoperilampus monguonensis and bitterling specimens from Shandong Province.As the results … More of the Expedition from 1995 to 1996, following points were found : 1) Rhodeus atremius, which was considered as an endemic species to Japan, was found in Zhejiang Province, China. 2) A bitterling having n=23 was found for the first time in China (Ueda et al., in press). 3) Ag-NORs of Rhodeus lighti and Tanakia himantegus were studied (Ueda et al., in press). 4) It was found that Rhodeus lighti which was considered as an endemic species to China, and Rhodeus uyekii which was considered as an endemic species to Korea are junior synonym of a Chinese bitterling Rhodeus sinensis (Akai and Arai, in press). 5) Syntypes of Acheilognathus meridianus consist of two species. 6) Tanakia lanceolata, which was not reported in any paper and book in China, was discovered in Liaoning Province (Arai et al., 1995). 7) Tanakia species was collected for the first time from Shanghai City. 8) A bitterling which seems to spawn in the autumn was descovered for the first time in China. 9) The cephalic sensory canals and suborbital bones of 9 Chinese species including subspecies, 15 Japanese species including subspecies, 1 Korean species and 1 European species were studied. Adult specimens of some species have the cephalic sensry canals characteristic to the juveniles, suggesting speciation by peadomorphosis in bitterlings. Less
