Abstract
Hainanthereua albilineata gen. nov. et sp. nov. is described and illustrated based on specimens from Hainan Province, China. Morphological examination showed that these specimens belong to Thereuoneminae and share certain similarities with Thereuopodina Verhoeff, 1905. Phylogenetic reconstruction based on five genes (nuclear 18S and 28S rRNA, mitochondrial 12S and 16S rRNA, and cytochrome c oxidase subunit I) indicated that the specimens form a distinct and well-supported clade that is sister group to Thereuonema Verhoeff, 1904, so a new genus is accordingly established. Combining the evolutionary history and biogeographic framework of Thereuoneminae, this study revealed the evolutionary significance of Hainanthereua gen. nov. in the context of the Peninsular Indian Plate as a biotic ferry implicated in the origin of East and Southeast Asian lineages. Morphological similarities between Hainanthereua and Thereuopodina are symplesiomorphies of a clade that includes these two genera, Thereuonema and Thereuopoda Verhoeff, 1904.
