( Figs. 6–9 View FIGURES 1 – 12 , 47– 65 View FIGURES 37 – 48 View FIGURES 49 – 60 View FIGURES 61 – 72 ; Tab. 2 View TABLE 2 )

Eggs barrel-shaped; light brown prior to embryonic development; operculum round and convex; chorion light brown, reticulated, and usually opaque ( Figs. 7–9 View FIGURES 1 – 12 ), shiny in C. armigera ( Fig. 6 View FIGURES 1 – 12 ). The eclosion line evident under SM and indicated as a smooth band delimited by the AMPs ( Figs. 6, 8, 9 View FIGURES 1 – 12 ). With the development of the embryo, the red eyes of the nymph become evident through the chorion ( Fig. 6 View FIGURES 1 – 12 ). The aero-micropylar processes are circularly arranged in a row around the anterior pole, clubbed, and translucent ( C. aseada ) to white (remaining species) ( Figs. 6–9 View FIGURES 1 – 12 ).

The chorion surface of all species of Chinavia Orian studied here is reticulated under SEM, with circular or polygonal cells ( Figs. 47 View FIGURES 37 – 48 , 52, 56, 60 View FIGURES 49 – 60 ). In some species, these cells may be quite regularly hexagonal at the lateral wall ( Fig. 49 View FIGURES 49 – 60 ). The cells project inward in a funnel, appearing to bear a hole ( Figs. 49, 54, 58 View FIGURES 49 – 60 ). The operculum is similarly sculptured but with smaller cells at center ( Figs. 48 View FIGURES 37 – 48 , 50, 53, 57 View FIGURES 49 – 60 , 61, 62 View FIGURES 61 – 72 ). The eclosion line is wide and clearly evident, marked by several minute and irregular projections ( Figs. 51, 55, 59 View FIGURES 49 – 60 , 63 View FIGURES 61 – 72 ). The AMPs are moderately short and strongly clubbed, with their openings circular and apical ( Figs. 51, 54, 55, 58, 59 View FIGURES 49 – 60 , 63, 64 View FIGURES 61 – 72 ). Fine connector sheets among adjacent AMPs have been observed in some of the eggs of all species ( Figs. 51, 54, 55, 58 View FIGURES 49 – 60 , 64 View FIGURES 61 – 72 ). Under higher magnification, the AMPs surface is spongy ( Figs. 51, 55, 59 View FIGURES 49 – 60 , 65 View FIGURES 61 – 72 ).
