Dismorphia lysis lysis

( Plate 9 , Fig. 27).

The egg is 1179.9 µm long and 537.7 µm wide; it is 2.2 times longer than wide and its width/length ratio is ½; the maximum diameter is at the equator (Nh= 8). The egg is elongated citriform; the base is convex and smooth, 2.14 times wider than the little obtuse apex and flat cusp. The apical area is slightly sharpened just from where the longer ShA end, toward the seventh apical rib. They have 29 to 39 ribs (modes = 31, 37) extending from the base to the cusp; they are mostly straight and parallel, although there are also curves and diagonals at the apical area; most are alternate between axes and keep up intercostal spaces of constant amplitude, except at the apical (are expanded) and basal (are reduced) areas. There are 9 to 11 axes (LoA= 5 to 6 and ShA= 3 to 5), they are 2 or 3 times thicker than the ribs; they are reduced in thickness as they reach the base, where they arise from before the first rib. The ShA are separated from the cusp by 2 to 7 ribs, often 3 or 5. The grid is made up of rectangles that at the equator are almost 4 times wider than long; they reduce their intercostal distance and their size at the base. Roughness tenuous with both staining and backlighting. The eggs show radial and bilateral symmetry. The formulas observed are:>5L5C (LCLCLCLCLC, L2C2LCLCLC), 5L4C (2LCLCLCLC), 6L5C (2LCLCLCLCLC), 6L4C (2LC2LCLCLC), and 6L3C (3LC2LCLC). Color N0 0 A20M0 0.
