Limnocythere sp.

( Figure 10C, D )

Remarks

This species belongs to the stationis group of Limnocythere , characterized by a reduced seventh limb, which is significantly smaller than the sixth limb, and a similar carapace shape ( Martens 1990). The lack of post-ventral alae on the carapace indicates that it is not the widespread Limnocythere stationis ( Vávra, 1891) , which has previously been reported from Korea ( Lee et al. 2000). It is also sufficiently different from other species of the group to suggest that it is an undescribed species, but as no males were recovered, it is not described herein. On Jeju Island it was found at two localities (25 and 26), in a marsh and an irrigation pond.
