Material. Five specimens found in mosses around Hwanseongul area, Singi-myeon, Samcheok-si, Gangwon-do.
This species is very rare and has been reported only from Brazil ( Donner 1980) after the description from Mallorca island, Spain ( Donner 1962).
The general morphology of the Korean specimens coincides well with the original description except the location of two small processes which were described to be on sulcus base by Donner (1962). According to the observations of the Korean specimens, the two small processes were on the disc retractor instead of sulcus base. It seemed that Donner (1962; 1980) mistook the positions of the processes during observations. As Donner (1962) mentioned, these two processes could be observed in dorsolateral view only ( Fig. 6a View FIGURE 6 ). Donner (1962) observed that when the Spanish specimens contracted, they were covered with very thin shells and debris. The Korean specimens were not observed in shells.
