Serdia apicicornis Stål, 1860

(Figs. 11, 70–73; Tab. 2)

Eggs spherical; light green prior to embryonic development; operculum broadly round and convex; chorion translucent and granulated (Fig. 11). The eclosion line is not evident under SM, and the AMPs are circularly arranged in a row around the anterior pole, slightly displaced posteriorly, translucent, short, and clubbed (Fig. 11). The chorion surface is granulated under SEM, with perfectly circular projections evenly distributed (Figs. 70, 72). Although the egg may be described as spherical, the posterior pole is flatter than the anterior pole and bears traces of the adhesive material secreted by the female to glue the eggs to the substrate (Fig. 70). The operculum is similarly sculptured (Fig. 71), and the eclosion line is present as a narrow strip very near the AMPs, with smaller granules placed closer to each other (Fig. 72). Except for the eclosion line, the surface of the egg is remarkably uniform. The AMPs are very small, club-shaped, with circular and apical openings (Figs. 72, 73). Under higher magnification, the surface of the processes is slightly spongy (Fig. 73).
