Abstract

The taxonomy and phylogeny of the genus Tolypocladium are herein revised based on the most comprehensive dataset to date. Two species-level phylogenies of Tolypocladium were constructed: a single-gene phylogeny (ITS) of 35 accepted species and a multigene phylogeny (nrSSU, nrLSU, tef-1α, rpb1, and rpb2) of 27 accepted species. Three new species, Tolypocladium pseudoalbum sp. nov., Tolypocladium subparadoxum sp. nov., and Tolypocladium yunnanense sp. nov., are described in the present study. The genetic divergences of four markers (ITS, tef-1α, rpb1 and rpb2) among Tolypocladium species are also reported. The results indicated that species of Tolypocladium were best delimited by rpb1 sequence data, followed by the sequence data for the rpb2, tef-1α, and ITS provided regions. Finally, a key to the 48 accepted species of Tolypocladium worldwide is provided.

水蛭属的系统发育和系统分类学(蛇虫草科，蛇尾目)。

本文根据迄今为止最全面的数据，对龙骨属的分类和系统发育进行了修订。构建了2个物种水平的系统发育系统:35个被接受物种的单基因系统发育(ITS)和27个被接受物种的多基因系统发育(nrSSU、nrLSU、tef-1α、rpb1和rpb2)。本文报道了3个新种:pseudoalbum toolypocladium sp. nov.、subparadoxum sp. nov.和yunnanense sp. nov.。报道了四种标记(ITS、tef-1α、rpb1和rpb2)在蓼属植物中的遗传差异。结果表明，rpb1序列数据最适合划分toolypocladium的种类，其次是rpb2、tef-1α和ITS提供区域的序列数据。最后，给出了世界上48种公认的水蛭属植物的分类目录。
