Genus Eumedonia Forster

(Fig. 21 C, D)

The egg of Eumedonia eumedon (Esper) has a micropylar rosette surrounded by cells with rounded walls and a characteristic rough interior formed by undulating ridges. The transition zone is very narrow and the tubercleaeropyle zone has a moderately prominent structure of quadrangular cells with spongy background from which the tubercles hardly protrude (Munguira et al. 1988; Munguira 2006).
