A. crassa (Blanchard 1851)

(n=42) ( Fig. 5 : c1,2)

The egg elongation expressed as the height/length ratio is 55 ± 3% and the lateral flattening as the width/height ratio is 88 ± 3%. The general egg shape is ellipsoidal, flattened towards the anterior pole (76.6 %) (10) or ovoid (21.4%) (11). The color of the capsule is black (73.8%) (21) or dark brown (26.2%).The micropylar plate is lanceolate shaped (40),smooth (50), with edges above the capsule plane (60), black as well as the rest of the capsule (71) and the internal micropylar plate is open (80). Opercular angle is -22.72 ±3.22°. The shape of the operculum is orbicular (90), its color is always the same than the rest of the capsule (101) and the texture is rugose (111).

Ultrastructure ( Fig. 7 : c1,2): The capsule ultrastructure surface is cracked (121) as well as the micropylar plate ultrastructure surface (130), which also have lobulated edges. The micropylar cup has a veil (141) and the surface of the operculum is cracked (151).
