Leptidea amurensis japona 

( Plate 5 View Figure , Fig. 2).

The egg is 1596 µm long and 480.4 µm wide; its length is 3.33 times greater than its width at the equator; the width/length ratio is less than 1/3; (Nh= 37); its maximum diameter is at the equator, and it narrows toward the poles but is more accentuated toward the upper pole. Quasi-fusiform egg, convex base, somewhat smooth and a polygonal outline, 1.7 times wider than the acute apex and flat cusp; it has a great variety of arrangements in the grid, even in the eggs of the same female. There are 43 to 67 ribs, mostly straight; they are curved, sinuous, and diagonal at the poles, although they are not restricted to these areas; they are distributed longitudinally and alternate between axes. At the extremes, there is even bifurcated ribs or form a 'fork' between the intercostal spaces. The intercostal distances are of constant amplitude, except at the base where they are reduced. There are 9 to 11 axes relatively straight, 1.5 times thicker than the ribs, which can be bifurcated or fused in the apical zone, and rarely in the base-to-equatorial direction or present 3 ShA between LoA; the mini-axes are from 2 to 5, and they arise at the base and arrive before the equator. The grid has wide rectangles (4 times the width than the length), which reduce its amplitude toward the base. The ShA are separated from the perimicropylar area by 2 to 35 ribs; the latter number if the mini-axes are considered as ShA. In the intercostal spaces a slight roughness, with backlighting, is observed. The eggs are asymmetrical. The axes’ arrangement is very variable, which is why the following simple formulas are recognized: 8L3C, 8L2C, 7L4C,>7L3C, 6L4C, 5L5C, 7L2C, and 6L3C. Color N0 0A20M0 0.
