摘要	Branchinotogluma is one of the most diverse genera among the polynoids inhabiting deep-sea chemosynthetic environments. A total of 14 species have been described from the hydrothermal vents and cold seeps worldwide. Our phylogenetic analyses based on four genes (COI, 16S, 18S, and 28S rRNA) recovered the current Branchinotogluma as paraphyletic, with seven clades scattered in two main clades. The monophyly of the main clade composed of Branchinotogluma (except Branchinotogluma segonzaci), Branchipolynoe, and Peinaleopolynoe is supported by the presence of 20-21 segments with 9-10 pairs of elytra, ventral papillae starting from segment 12 in males, and arborescent branchiae. The monophyly of another main clade composed of B. segonzaci, Bathykurila, Lepidonotopodium, Levensteiniella, and Thermopolynoe is supported by the presence of usually 22-30 segments with 11 pairs of elytra and the lack of ventral papillae in females. In addition, our study recognized two new species, Branchinotogluma nanhaiensis sp. nov. and B. robusta sp. nov., based on specimens collected from the deep-sea cold seeps in the South China Sea. Both the morphology and molecular phylogenetic analyses support the validity of the two new species and the sister relationships between B. nanhaiensis and B. japonicus and between B. robusta and B. pettiboneae as well.
