Abstract

A new species of trombiculid mite, Walchia (W.) koshikiensis is described and illustrated. The new species resembles Walchia ogatai (Sasa et Teramura, 1951) but is obviously different from W. ogatai in the pentagonal shape of the scutum, which is wide than long, and in having the nude galeal setae.
