A. elegans (Philippi 1863)

(n=27) (fig. 6: b1,2)

The egg elongation expressed as the height/length ratio is 60 ± 2% and the lateral flattening as the width/height ratio is 92 ± 2%. The general shape of the egg is ovoid (75%) (11) or ellipsoidal with the anterior pole flattened (25%) (11). The color of the capsule is black (74.1%) (21) or dark brown (25.9%), with smooth texture (63%) (30) or slightly rugose (37%). The micropylar plate is ensiform shaped (78%) or lanceolate (22%) (42), with smooth texture (50), edges above the capsule plane (60), black colored (71) and the internal micropylar plate is closed (81). Opercular angle is -27.38 ±4.30°. The operculum shape is orbicular (90), the coloration is always the same than the rest of the capsule (101) and rugose (111).

Ultrastructure ( Fig. 8 : b1,2): The capsule ultrastructure surface is cracked (121) as well as the micropylar plate ultrastructure surface (130). The micropylar cup has a veil (141). The ultrastructure surface of the operculum is rugose (153).

A1-C1, micropylar plate ultrastructure; A2-C2 ultrastructure surface of the operculum. The order of the micropylar plates and operculum from top to botom is A. grylloidea, A. elegans, A. mesoauriculae.
