Diagnosis. Female: Sternum VII rectangular, with a small hemispherical membranous area posteriomedially, not fused to sternum VIII. Median sclerites on sternum VIII are with dark brown inner keel; rest of the sclerites dark brown, longer than the keel, the sclerites are hardly wider than long. Further two pairs of sclerites present at the lateral edges of median sclerites, and at the posterolateral edge of the segment.

Distribution and ecology. This spring species is known only from females. Previously, it was reported from the Primorsky and Magadan areas of Russia, indicating a relatively wide distribution along the Pacific ranges. The new locality extends its known distribution southwards to western edge of the Korean Peninsula ( Fig. 32 ). The present specimen was collected together with potamal species for example Amphinemura coreana Zwick, 1973a . New for the Korean Peninsula.
