Enantia albania nuria

( Plate 6 , Fig. 7).

The egg is 1197 µm long and 433.2 µm wide; it is 2.76 times longer than wide and their width/length ratio is a little less than 1/3; the maximum diameter at 5/8 of its length from its base; near its base the thinning is accentuated, and the neck is formed from the first basal fifth (Nh= 2). The egg is elongated, obpyriform. Its base is convex-hemispherical, reticulate and less broad than the cusp, sometimes it is curved. The apex and cusp are slightly obtuse and rounded. There are 31 to 34 ribs, although on average, they are 33, the most frequent are 34; they are mostly straight, but in the apical and basal areas, they are curved; generally, they coincide between axes, although some alternate. The intercostal spaces are of constant amplitude, except at the base where they are reduced significantly, and the ribs are disorganized until forming a grid with irregular polygons of more than four sides; toward the cusp, intercostal distances are reduced, but to a lesser degree. There are 13 axes (LoA = 7 and ShA= 6); these are laminar and straight, some are zigzagging in the neck; they are usually 2 times wider than the ribs. They thicken more toward the apical area, although they keep the same proportion throughout their length. The ShA are separated from the perimicropylar area by 2 to 4 ribs, often 3. The grid is made up of rectangles, less than 2 times wider than long; they reduce their size and proportion toward the base and are subsquare on the neck. The symmetry of the egg is bilateral. Formula 7L6C (2LCLCLCLCLCLC). Color N0 0 A20M0 0.
