Pallantia macunaim

( Figs. 87–90 ; Tab. 2 )

Eggs barrel-shaped, light brown to greenish; operculum flat to slightly convex; chorion white-translucent, with great amount of thin prolongations ( Grazia & Frey-da-Silva 2001; Panizzi & Grazia 2001). Aero-micropylar processes long and filiform.

In SEM, chorion spinose: the whole surface is covered by long and thin spines ( Figs. 87, 88 ), with different heights and connected to each other by fine sheets ( Fig. 89 ). The more or less hexagonal reticulations underlying the thin prolongations, as described by Grazia & Frey-da-Silva (2001), were not observed. At oval area where the egg is fixed to another in the egg mass, a substance recovers the spines and distorts the sculpture pattern ( Fig. 87 ). Surface sculpture pattern at operculum does not differ from the lateral wall; the eclosion line is not visible before hatching ( Fig. 88 ). Aero-micropylar processes tubular, longer in larger diameter than the chorionic spines, with a circular apical opening ( Fig. 90 ).
