A. grylloidea (Westwood 1859)

(n=37) ( Fig. 6 : a1,2)

The egg elongation expressed as the height/length ratio is 60 ± 5% and the lateral flattening as the width/height ratio is 85 ± 4%. The general shape of the egg is ovoid (68%) (11) or ellipsoidal with the anterior pole flattened (32%) (11). The capsule is brown (20) and rugose (32).The micropylar plate is acuminate shaped (68%) (41) or lanceolate (32%) (40), rugose (52),with edges above the plane of the capsule (60),brown colored (70) and the internal micropylar plate is closed (81). Opercular angle is -16 ± 0.5°. The operculum has an orbicular shape (90), brown color (100) and its texture is highly rugose and distributed uniformly along the opercular surface (111).

Ultrastructure ( Fig. 8 : a1,2): The capsule ultrastructure surface is rugose (123), as well as the micropylar plate ultrastructure surface (131). The micropylar cup has a veil (141). The ultrastructure surface of the operculum is rugose (153).
