Dispersal and evolution of the marine fly in the South America

为了明确南美海岸多面蝇种的系统发育位置和起源，我对南美海岸多面蝇进行了调查，对收集到的标本进行了分类，并利用形态学数据和DNA序列数据分析了它们的系统发育关系。通过在南美洲的分布调查，发现Cymatopus属分布于热带至亚热带，并发现了日本特有种Conchopus borealis。此外，南美地区特有的属也没有被发现。

To clarify the phylogenic position and origin of the South American species of marine-shore dolichopodid flies, I have conducted surveys of these flies on South America, classified the collected specimens, and analyzed their phylogenetic relationships using morphological data and DNA sequence data.As a result of distribution investigation in the South America, the genus Cymatopus distributed the tropical to subtropical zone, and the Japanese endemic species Conchopus borealis were founded.In addition, the genus peculiar to South America area was not founded.
