D. theucharila avonia (transparent form)

( Plate 9 , Fig. 32).

The egg is 2036.7 µm long and 641.8 µm wide; it is 3.18 times longer than it is wide and its width/length ratio is 1/3; the maximum diameter is shortly after the base to the equator (Nh= 17). The egg is ellipsoidal elongated and acuminate in the upper pole; the base is convex and 3.3 times wider than the sharp apex and flat cusp. The apical area is sharpened from the sixth apical rib. They have 48 to 65 ribs that extend from the base to the cusp; generally, they are straight, parallel, and alternate between axes, although they also coincide; they keep up intercostal spaces of constant amplitude, except in the basal area (are reduced). In the apical zone, curved ribs are present, and the intercostal distance is greater. There are 8 or 9 axes (LoA and ShA= 3 to 5), they are laminar and 3.2 times thicker than the ribs; the intercostal cells are concave, so the axes enhance the relief of the chorion. The ShA are separated from the cusp by 1 to 6 ribs, often 4. The grid is rectangular; at the equator, those rectangles are 5.7 times longer than they are wide, they are slightly reduced at the ends, noticeably at the apex. Inconspicuous roughness highlighted with backlight; minimal staining of the relief with roughness. The eggs are asymmetric or have radial or bilateral symmetries. The following formulas are recognized:>5L3C (3LCLCLC, 2LC2LCLC), 4L4C (LCLCLCLC, 2LCL2CLC), 3L5C (L2CL2CLC), and 5L4C (2LCLCLCLC). Color N0 0A20M0 0.
