Heterocypris incongruens (Ramdohr, 1808)

For synonym list see Meisch (2000).

Remarks. Only one adult female specimen was recovered from the littoral zone of the Karasuma Peninsula in the month of April. This species is probably only an occasional visitor to the lake, washed in from temporary habitats, such as rice fields, puddles and ditches surrounding the lake, where it is often very abundant. Locality (Fig. 1): 25.
