碩士 === 國立臺灣師範大學 === 生命科學研究所 === 97 === Nine spiecies of Leucauge spiders are reviewed from Taiwan in this study, among which one species, L. taiwanensis sp. nov is new to the science. L. celebesiana (Walckenaer, 1842), L. crucinota (Bösenberg & Strand, 1906), L. subblanda Bösenberg & Strand, 1906, and L. wulingensis Song & Zhu, 1992, are newly recorded from Taiwan. L. venusta was excluded from the spider fauna of Taiwan. Forty-five morphological characters of 19 leucaugines species and Tetragnatha as Outgroup were included in a phylogentic analysis. The results showed that Leucauge can be divided into two subgroups. L. argentina and L. crucinota belong to a monophyletic group, which might belong to a new genus. The other Leucauge species and Opadometa form another subgroup with Mesida as a sister group. The results suggest that genus Leucauge is a polyphyletic assamblage. A further classification study is needed. The present study will provide a basic knowledge for the diversity conservation of spiders in Taiwan.
