Genus Iolana Bethune-Baker

(Fig. 12 E, F)

The egg of Iolana debilitata (Schultz) has a clearly distinctive morphology, with the annular zone and the depressed transition zone formed by large polygonal cells with a grainy background. The micropylar rosette is similar to the other cells in the annular zone and can scarcely be distinguished. The tubercle-aeropyle zone has large, profound cells that are very narrow on the edge of the area and become wider in the centre where they resemble a honeycomb. On the intersections of the cells there are aeropyles but no tubercles.
