Abstract

Six unrecorded mites of the family Tarsonemidae in Japan were collected from various plants, and their morphological features were examined.The species are as follows:<br>1. Tarsonemus confusus EWING, 1939<br>2. T. scaurus EWING, 1939<br>3. T. setifer EWING, 1939<br>4. T. smithi EWING, 1939<br>5. T. occidentalis EWING, 1939<br>6. Daidalotarsonemus tessellatus DE LEON, 1956<br>Among the genus Tarsonemus, T. confusus, T. scaurus and T. setifer are common and widely distributed in Honshu, Shikoku and Kyushu, but T. smithi and T. occidentalis are not so common. The identification of these five species was made only by their males due to the difficulty in finding morphological differences in their females.<br>The genus Daidalotarsonemus DE LEON, 1956 was recorded for the first time in Japan in this paper. Only a few females of D. tessellatus were collected on Evodia-plant in Tokyo.
