First Record of Riccardoella (Proriccardoella) triodopsis (Acariformes: Trombidiformes: Ereynetidae) from Japan, with Additional Morphological Information

Abstract

The parasitic mite Riccardoella (Proriccardoella) triodopsis Fain and Klompen, 1990 was sampled from two localities in Chiba prefecture, Japan. The sampled mites were identified based on palps and leg chaetotaxy and structure of famulus on tibia I. This study is represented by the second record of R. triodopsis inhabiting the pulmonate snail and the first discovery in Japan.
