2 NEW SPIDER-MITE SPECIES OF THE SCHIZOTETRANYCHUS-CELARIUS COMPLEX (ACARI, TETRANYCHIDAE)

Two new species of the genus Schizotetranychus were described. They have formerly known as infra-specific forms of Schizotetranychus celarius (Banks). Schizotetranychus miscanthi Saitō, n. sp. was collected from a perennial grass, Miscanthus sinensis Anderss, in Kyushu, Shikoku and Okinawa. It differs from S. celarius in the relative lengths of several dorsal setae and their arrangements. Schizotetranychus longus Saitō, n. sp. was collected from a dwarf bamboo, Sasa senanensis (Franch. et Sav.) in Hokkaido and Shikoku. It differes from S. celarius in the relative lengths of several dorsal setae, and from S. miscanthi n. sp. in the form of the empodial claws and in the position of the dorsocentral setae (C1). © 1990, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
