( Figs. 10, 66–69; Tab. 2)
Eggs barrel-shaped; brown prior to embryonic development; operculum round and convex; chorion light brown, almost translucent, and reticulated ( Fig. 10). The eclosion line is evident under SM, as a smooth paler band delimited by the AMPs ( Fig. 10). The aero-micropylar processes are circularly arranged in a row around the anterior pole, white, short, and clubbed ( Fig. 10). The chorion surface is reticulated under SEM, but the sculpture pattern may be obliterated in some portions of the egg ( Fig. 66). Remnants of adhesive material are evident at the posterior pole; at the lateral wall, the sculpture pattern is clearly altered in the area where the egg was fixed to another in the egg mass ( Fig. 66). Most of the chorion is recovered by shallow cells with irregular edges forming truncated rough masses. The operculum is similarly sculptured ( Fig. 67). The eclosion line is evident as a broad depressed band, in which there are smaller rough masses, more widely spaced near the AMPs ( Fig. 68). The AMPs are moderately short and distinctly clubbed, with circular and apical openings ( Fig. 68). Their surface is clearly spongy under higher magnification ( Fig. 69).
