Egg. Regular oval-shaped ( Fig. 57 ), total length 440 μm, equatorial width 320 μm (n = 1). Collar stalked, short, and moderately wide, rim flanged, and irregularly incised; sides with weakly incised ribs ( Figs. 59−60 ). Anchor is mushroom-shaped and flat; the pedicel is relatively long ( Fig. 59 ). The anchor surface is covered with globular bodies distributing over the whole area of the anchor plate ( Fig. 59 ). Chorion is covered with puncture-like follicle cell impressions; pits uniform, coarse, round shaped with equally shallow depth at the equator and poles ( Figs. 57−58, 61 ); follicle cell impression walls are not elevated. The micropylar line is closer to the anterior pole ( Fig. 57−58 ); the micropylar canals are not visible; orifices are very small, poorly visible, and directed towards the equator without noticeable rosettes ( Figs. 57, 61 ).

Comments. The egg of this species differs from that of K. exilis in the chorion structure, which is coarsely regularly pitted throughout and the follicle cell impression walls are not elevated. The chorion of K. exilis is covered with coarse and deep pits of varying size and shape, especially in the micropylar area, where the orifices are surrounded by rosettes of large petal-shaped pits; the walls of the pits are smooth, wide, and raised above floors.

Distribution. Kamimuria lyubaretzi was found in the south of Primorsky Krai, mostly in the streams of the East Manchurian Mountains in the Krounovka River, Razdolnaya River Basin. This species has also been reported from South Korea ( Hwang & Murányi 2020).
