D. theucharila avonia

(yellow form) ( Plate 9 , Fig. 31).

The egg is 1884 µm long and 601.2 µm wide; it is 3.13 times as long as it is wide, and its width/length ratio is 1/3; the maximum diameter is almost constant from the base to the apical quarter (Nh= 13). The egg is ellipsoidal elongated and acuminate in the upper pole; the base is convex or quasi-flat, 3.3 times wider than the acute apex and rounded cusp. The apical area is sharpened from the fifth apical rib. They have 42 to 63 ribs (mode = 58), which extend from the base to the cusp; generally, they are straight, parallel, and alternate between axes, although they also coincide. They maintain intercostal distances of constant amplitude, except in the basal area (are reduced); in the apical zone, there are curved ribs with larger intercostal spaces. There are between 7 to 9 axes (LoA and ShA = 3 to 5), which are laminar and almost 3 times thicker than the ribs. The intercostal cells are concave or depressed, so the axes enhance the relief of the chorion. The ShA are separated from the cusp by 1 to 6 ribs, often 3 or 4. The grid is rectangular and at the equator, the rectangles are more than 5 times wider than long; they are gradually reduced toward the extremes. Weak roughness with slight staining of the relief. The eggs are asymmetric or show radial and bilateral symmetries. The following formulas are recognized:>4L4C (LCLCLCLC), 4L3C (2LCLCLC), 3L5C (L3CLCLC), 5L4C (2LCLCLCLC), and 4L5C (L2CLCLCLC, L3C3L2C). Color N0 0 A10M0 0.
