This is the first record of the genus from Asia. The new species is morphologically similar to P. garthi, but differs from the latter in the following features: 1) lateral cephalic lobe of head not strongly produced; 2) head lacking antennal sinus; and 3) posteroventral corner of epimeral plate 3 rounded. Morphology of maxillae 1 and 2, and mandible, and gut contents (harpacticoid Copepoda) of P. mawatarii indicate that the feeding type of the species seems to be, at least facultatively, carnivorous.Zoological Society of Japan日本動物学会2010-07engjournal articleVoRhttp://hdl.handle.net/2115/79262https://doi.org/10.2108/zsj.27.6150289-0003AA10545874Zoological Science277615626https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/79262/1/Zoological%20Science_27_615-626%282010%29.pdfapplication/pdf640.42 KB2010-07
