Abstract
A new species of the ostracod genus Scottia Brady and Norman, 1889 from Kanazawa, western Honshu, Japan is described. This species is only the third living representative of this genus. It is most similar to the populations of S. pseudobrowniana Kempf, 1971 from western Europe, but it is smaller, and has unique features of the hemipenes, Zenker organs, antennae and mandibles. A prominent projection on the dorsal lobe of the hemipenes gives this species its name, Scottia birigida sp. nov.. It lives in wet leaf litter around the discharge of a spring, leading a semi-terrestrial lifestyle. This is the first record of Scottia and the subfamily Scottiinae Bronstein, 1947 from Japan and North East Asia, and significantly increases the known distribution of these taxa. This record of Scottia from Japan, together with numerous reports from Europe and two areas in the USA, indicates that in the northern hemisphere this genus is probably widespread. A key to the subfamily Scottiinae is also provided.References
