项目摘要

The present project was made during 1986 to 1987. The following results have been obtained so far.1. In 1986, I made an intensive survey of Mnais damselflies at 20 localities of the Island of Hokkaido and ascertained that in the island M. costalis populations always inhabit alone (Suzuki, 1987b).2. In 1986 and 1987, I and my collaborator (Mr. H. Kadowaki) made an intensive survey of this group at about 250 localities of Shimane Prefecture including Oki Islands (Suzuki & Kadowaki, 1986, 1987a, c). In Oki Islands (Dogo Island) only M. nawai Chugoku group population inhabits. In Shimane Prefecture proper M. nawai Chugoku group and M. pruinosa Nankai group populations are distributed. They occasionally co-occur in the same stream.3. In 1986 and 1987, I made an intensive survey of this group at many localities of Kyushu including Goto Islands and Koshiki Islands. In Kyushu, the following three Mnais species are distributed: 1. M. nawai Kyushu group, 2. M. pruinosa Nankai group, and 3. M. pruinosa Saikai group. Two of them occasionaly co-occur in the same stream. From Goto and Koshiki Islands, unique populations, which should be treated as independent subspecies respectively, were discovered. In particular, the Koshiki population is very important from the viewpoint of speciation ofMnais damselflies in the Japanese Islands. The combination of male and female forms of the population apparently corresponds to the undescribed new species M. sp., which is distributed in central Honshu (Suzuki, in preparation).

本项目是在1986年至1987年期间进行的。到目前为止，已经取得了以下成果. 1986年，笔者在北海道的20个地点对曼氏豆娘进行了深入调查，确定了在M. costalis种群总是单独栖息（Suzuki，1987 b）。在1986年和1987年，我和我的合作者H。Kadowaki）在包括隐岐群岛在内的岛根县约250个地方对这一群体进行了深入调查（Suzuki & Kadowaki，1986，1987 a，c）。在隐岐群岛（道后岛）只有M。居住着日本中部地区的人口。在岛根县的M。nawai Chugoku群和M.南海群种群分布广。它们偶尔会在同一条河流中同时出现。在1986年和1987年，我在包括后藤群岛和越城群岛在内的九州许多地方对这一群体进行了深入的调查。在九州，以下三种Mnais物种分布：1。M. nawai Kyushu group，2. M. pruinosaNankai组和3. M.粉蝶组。其中两种在同一河流中同时出现。在后藤和越敷岛发现了独特的种群，应分别作为独立的亚种对待。特别是，Koshiki人口是非常重要的，从物种的观点ofMnais豆娘在日本群岛。该种群的雄性和雌性形式的组合显然对应于未描述的新种M。例如，在本州岛中部分布（铃木，准备中）。
