Dismorphia arcadia  ssp. nov  .

( Plate 8View PLATE 8, Fig. 20).

The egg is 1100.1 µm long and 482.2 µm wide; it is 2.29 times longer than wide and their width/length ratio is 4/9; the maximum diameter is at the equator (Nh= 16). The egg is citriform elongated. The base is convex and partly smooth, 2.5 times wider than the obtuse apex and flat cusp. In the apical area, there are curved ribs due to the concavities between axes; in the perimicropylar border, there is a row where the ribs become disorganized and made-up multiple polygonal grids. There have 44 and 55 ribs (mode = 47); most are straight, except in the apical area where they are curved; generally alternating between axes, although in some sections they may coincide. They extend longitudinally and alternately a tenth after the base to the cusp; they form intercostal spaces of constant amplitude, except in the base where they are reduced slightly and in the apical zone where they conspicuously expand. There are between 11 and 12 axes (LoA= 5 to 8, ShA= 3 to 7) 2.2 times thicker than the ribs. In a single case, there is a mini-axis. The ShA are separated of the cusp by 1 to 5 ribs, often 3. The grid is made up of wide rectangles (up to almost 5 times longer than the width) that reduce their amplitude a little toward the base. Absent roughness; dim relief is observed in the incident light, but there is no staining in the intercostal cells. The eggs are asymmetric or show radial or bilateral symmetries. The following formulas are recognized:>7L5C (2 LCLC 2 LCLCLC, LCLC 2LC2 LCLC, 3 LCLCLCLCLC), 6L6C (LCLCLCLCLCLC, 2LCLCLCL2CLC), and 6L5C (2 LCLCLCLCLC), that are the most frequently; 8L3C (3LC3LC2LC), 7L4C (2 LCLC 2LC2LC), and 5L7C (L2CLCLCL2CLC).
