A new species of the genus Glossobalanus (Hemichordata, Enteropneusta, Ptychoderidae) from China
A morphological and molecular analyses of a newly discovered species, Glossobalanus weii sp. nov., from Danzhou city, Hainan Island, China is presented. Several morphological characters distinguish this new species, while molecular analyses confirm significant genetic divergence from its recognized congeners (p-distance > 0.25 in mitochondrial genomes). Phylogenetic analyses place the new species in a distinct sister clade to G. polybranchioporus, which is afforded first-class state protection in China. An updated retrieval table is provided for the eight species of Hemichordata found in China. Hemichordate diversity remains underestimated and this new species emphasizes the need for their ongoing conservation in southern China.
