Dismorphia mirandola discoloria

( Plate 9 , Fig. 29)

. The egg is 1322.4 µm long and 565.4 µm wide; it is 2.34 times longer than it is wide and its width/length ratio is 3/7; the maximum diameter is at the equator (Nh= 5). The egg is elongated citriform with a convex base, 2.5 times wider than the little obtuse apex and flat cusp. The apical area is sharpened from where the most distal ShA begin, toward the sixth rib. They have 36 to 40 ribs (modes = 37, 39; mean = 38); generally, they are straight and parallel, but diagonal, and curves are also observed in the apical zone; they extend from the base to the cusp; most alternate and keep up intercostal spaces of constant amplitude, excepting at the apex where they are broader, while at the base, they are markedly reduced. There are between 8 and 9 axes (LoA= 5 and ShA= 3 to 4), 2.5 to 3 times thicker than the ribs and reduce their thickness as they approach the base. The ShA are separated from the cusp by 3 to 6 ribs, often 5; the ShA show a greater relief than the LoA. The grid is rectangular, in the equator, the rectangles are 6 times wider than long and reduce in amplitude, proportion, and size in the base. The eggs exhibit bilateral symmetry. Conspicuous roughness is noticed mainly with backlight, but without getting stained. The arrangement of the axes is variable, and the most frequent formula is 5L4C (2LCLCLCLC) and less frequent: 5L3C (2LCLC2LC). Color N0 0A10M0 0.
