抄録

Eotetranychus tiliaecola Ehara and Gotoh, sp. nov. is described and illustrated from Tilia maximowicziana Shirasawa (Tiliaceae). It was also found to occur on T. japonica (Miq.) Simonkai in Hokkaido, Japan. The aedeagus of this species closely resembles that of E. tsugaruensis Ehara, 1989, but differs in having the distal part strongly sigmoid and its termination more slender, and in the widely concave dorsal margin of the shaft.
