中国特有的4种串珠藻科植物，红东串珠藻（Batrachospermum hongdongense Xie & Feng）、长梗串珠藻（Batrachospermum longipedicellatum Hua & Shi）、弯叶熊藻（Kumanoa curvata（Shi）维斯）等，和Kumanoa intorta（Jao）Entwisle等，的多位点数据进行分析，以评估其系统发育的位置。利用核基因（核糖体SSU）、叶绿体基因（rbcL）和线粒体基因（COI和cox 2 - 3 spacer）的多位点分子数据以及形态学研究，确定了这些特有种在Batrachospermales内的系统发育关系。红东蝙蝠葛（Batrachospermum hongdongense）和B. longipedicellatum以前被置于Batrachospermum组Batrachospermum，但根据本研究的数据，应将其转移到节蠕虫总科。Kumanoa curvata和K. intorta显然属于新建立的Kumanoa属。
Four endemic Batrachospermaceae species in China, Batrachospermum hongdongense Xie & Feng, Batrachospermum longipedicellatum Hua & Shi, Kumanoa curvata (Shi) Vis et al., and Kumanoa intorta (Jao) Entwisle et al., were analyzed with multilocus data in order to assess their phylogenetic placement. Multilocus molecular data from one nuclear gene (the ribosomal SSU), one chloroplast gene (rbcL), and two mitochondrial genes (COI and the cox2‐3 spacer) as well as morphological studies were used to determine the phylogenetic relationships of these endemic species within the Batrachospermales. Batrachospermum hongdongense and B. longipedicellatum had previously been placed in Batrachospermum section Batrachospermum, but based on the data from this study they should be transferred into section Helminthoidea. Kumanoa curvata and K. intorta clearly belong to the newly established genus Kumanoa.
