Gyretes nubilus Ochs, 1965

(Figs. 2–5)

Description. Eggs. Cylindrical, length 1.12–1.69 mm, width 0.28–0.48 mm (n = 10); dark brown (just before eclosion) (Fig. 2). As the embryo develops, the egg becomes wider from the anterior pole toward the posterior pole. The chorion is thick, sculptured in most of the egg, except for the ventral surface, which is flat and smooth (Figs. 2–5). The chorion consists of rounded or quadrangular reticulation with irregular borders (Fig. 4). The micropylar projection is inserted into a depression in the center of the anterior pole and is connected to the depression by four branches (Figs. 3, 5).
