Chinavia armigera (Stål, 1854), Chinavia aseada (Rolston, 1983), Chinavia brasicola (Rolston, 1983), Chinavia runaspis (Dallas, 1851)

(Figs. 6–9, 47–65; Tab. 2)

Eggs barrel-shaped; light brown prior to embryonic development; operculum round and convex; chorion light brown, reticulated, and usually opaque (Figs. 7–9), shiny in C. armigera (Fig. 6). The eclosion line evident under SM and indicated as a smooth band delimited by the AMPs (Figs. 6, 8, 9). With the development of the embryo, the red eyes of the nymph become evident through the chorion (Fig. 6). 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).

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