【 摘 要 】

References(20)Cited-By(2)Dolomedes senilis Simon 1880 is newly recorded from Japan using the specimens collected from Hokkaido. The species is easily separated from other Japanese congeners by its unique appearance. One new species Dolomedes pegasus is also described using specimens collected from Tohoku district, northern part of Honshu, Japan. Dolomedes pegasus resembles D. sulfureus and D. angustivirgatus, but can be distinguished from them by shorter legs, barrel-shaped epigynum, shorter male palpal tibia and smaller tibial apophysis. The mt-COI partial sequence data of these species as well as D. zatsun are added to the previous data set and their phylogenetic placements among Japanese species are inferred. As a result, D. senilis and D. pegasus share the same clade with D. sulfureus, and D. zatsun shares the same clade with D. raptor.
