Zhi
Wang, Yanjie Zhang, and Jian-Wen Qiu (2018) Marphysa hongkongensa
n. sp. (Annelida: Eunicidae) is described based on samples from the
intertidal zone of Tolo Harbour, Hong Kong. This new species belongs to
the Marphysa sanguinea
species complex. It is characterized by a subacicular hook from
chaetiger 26-58 to the posterior end, branchiae with up to 5-10
filaments from chaetiger 14-35 to the posterior end, and four types of
pectinate chaetae. Molecular analyses indicated that the cytochrome
oxidase c subunit I gene and
16S RNA gene of Marphysa hongkongensa diverged from the
corresponding sequence of the closest related species of Marphysa in GenBank by 19.5% and
12.1%, respectively. An identification key is provided for species in
the Marphysa sanguinea
complex along the Chinese coast.
Key words: Bait worm, Pectinate chaetae,
Phylogeny, Polychaete, Tolo Harbour.
