The pseudoscorpion genus Nipponogarypus (Pseudoscorpiones, Olpiidae) found in seashore habitats in Japan and Korea

Abstract

Some pseudoscorpions (Arachnida: Pseudoscorpions) occur in seashore habitats where they are typically found under driftwood or rocks. Here we review the genus Nipponogarypus Morikawa, 1955 from littoral habitats in Japan and South Korea and describe a new species, Nipponogarypus seosanensis sp. nov., from the Korean Peninsula. We also elevate two former subspecies to species rank: N. enoshimaensis enoshimaensis Morikawa, 1960 = N. enoshimaensis Morikawa, 1955, and N. enoshimaensis okinoerabensis Morikawa, 1960 = N. okinoerabensis Morikawa, 1960, stat. nov. The distribution of all Nipponogarypus species is mapped, and an identification key for the species is provided.
