Taxonomic notes on Dolomedes nigrimaculatus (Araneae: Pisauridae) from Korea

抄録

A poorly known nursery web spider species, Dolomedes nigrimaculatus (Araneae: Pisauridae), is redescribed on the basis of Korean specimens, with a new junior synonym, Dolomedes jirisanensis which has been treated wrongly as a nomen nudum. Dolomedes nigrimaculatus is considered a sister species of D. zatsun from Okinawa Island, Japan, which have several morphological characteristics in common. Detailed description and remarks on the synonymy and intraspecific variation in its body coloration and shape of copulatory organs of D. nigrimaculatus are provided, with a key to all Korean Dolomedes species.
