status

 

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

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

Eggs barrel-shaped; light brown prior to embryonic development; operculum round and convex; chorion light brown, reticulated, and usually opaque ( Figs. 7–9View FIGURES 1 – 12), shiny in C. armigera  ( Fig. 6View FIGURES 1 – 12). The eclosion line evident under SM and indicated as a smooth band delimited by the AMPs ( Figs. 6, 8, 9View FIGURES 1 – 12). With the development of the embryo, the red eyes of the nymph become evident through the chorion ( Fig. 6View 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. 6–9View FIGURES 1 – 12).

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