March 2020 The
present study describes Pontopolycope
orientalis sp. nov. (Polycopidae), which was collected from the
shallow sandy bottom off of Nagannu Island, Okinawa Prefecture,
southwestern Japan. This new species is the first living representative
of Pontopolycope from the
Indo-Pacific region. We also provided a key to identifying five living
congeners throughout the world’s oceans. Since Pontopolycope is defined by the
morphological characteristics of the carapace, the following five
fossil and subfossil (empty valve) species of Polycope (Polycopidae)
are moved to Pontopolycope: Pontopolycope luxuriosa (Herrig,
1964) comb. nov., P. sanctacatherinae
(Whatley and Downing, 1983) comb. nov., P. krauseae (Herrig, 1994) comb.
nov., P. proboscidea (Herrig,
1994) comb. nov., and P. isolata
(Whatley, Jones and Wouters, 2000) comb. nov. Finally, the nucleotide
sequence data of three genes (18S rRNA, 28S rRNA, and mitochondrial
cytochrome c oxidase subunit 1) of the new species are provided for
future systematic and phylogenetic studies. Key words: Pontopolycope, Myodocopa, new species, new combination, southwestern Japan, Indo-Pacific, molecular data. Citation: Tanaka H, Kondo Y, Ohtsuka S.
