Dismorphia astyocha

( Plate 8 , Fig. 21).

The egg is 1557.2 µm long and 538.1 µm wide; it is 2.9 times longer than wide and their width/length ratio is 1/3; the maximum diameter is at the equator (Nh= 10). The egg is quasifusiform, and the distal pole is acuminate; the base is convex-hemispherical and smooth, almost 3 times wider than the acute apex and flat cusp. The apical area is quite sharp, just from where the longest ShA start, toward the eighth rib. They have 36 to 40 ribs (mode = 38); generally, they are straight, but also diagonal and curved in the apical zone; they extend from just before the base to the cusp; most are coincident between axes and keep up intercostal spaces of constant amplitude, excepting at the apex where they are wider, and at the base where they are reduced. There are 9 or 10 axes (LoA = 5 to 6 and ShA = 4 to 5), which are twice as thick as the ribs; in two cases, it was found a mini-axis (below the equatorial zone). The ShA are separated from the cusp by 3 to 10 ribs, often 5. The grid is made up of rectangles (a few irregular ones); at the equator, these are 4 times longer than wide and conspicuously reduced in amplitude and size at the base; also in the apical area but less accented. Eggs are asymmetrical or show radial or bilateral symmetries; the arrangement of the axes is variable, and the formulas are>5L5C (LCLCLCLCLC, 2L2CLCLCLC), 6L4C (2LCLCLC2LC), and 5L4C (2LCLCLCLC).
