Galgupha (Gyrocnemis) fossata

( Figs. 7–12 ).

Eggs were deposited on the host plant inflorescences and laid singly ( Fig. 7 ).

Description. Egg cylindrical with rounded ends, slightly wider at anterior pole, white; chorion shiny and translucent ( Fig. 8 ). Chorion surface, under SM, with small protuberances ( Fig. 8 ); under SEM, dense granulation evi- dent, interspaced with larger tubercles, usually with faint longitudinal carinae ( Figs. 9–11 ). Length: 0.9 ± 0.04 (0.8– 1.0); width: 0.6 ± 0.07 (0.5–0.7) (n = 20). MP circularly arranged around anterior pole but slightly displaced posteriorly ( Fig. 10 ); mean number of MP 7 ± 1.5 (4–10). Each MP white, short, almost indistinguishable from the chorionic sculpture under SM, stalked, oblong, capitate, with transverse constriction near middle; apical opening circular; under higher magnification, surface irregular but not spongy ( Fig. 12 ).

FIGURES 1–12. Eggs of Galgupha (Euryscytus) difficilis and Galgupha (Gyrocnemis) fossata. 1— Eggs of G. (E.) difficilis laid in pair, at right angle to each other, attached to branch of Buddleia brasiliensis, viewed with stereomicroscope (SM). 2–6— Eggs of G. (E.) difficilis viewed with scanning electron microscope (SEM): 2— lateral view, 3— anterior view, 4— magnification of anterior pole in lateral view, 5— magnification of anterior pole in anterior view, 6— micropylar process, with circular apical opening. 7–8— Eggs of G. (G.) fossata in SM: 7— Eggs laid singly (arrows), attached to inflorescence of B. brasiliensis, 8— Egg attached to branch of the plant, with conspicuous chorion sculpture. 9–12— Eggs of G. (G.) fossata viewed with SEM: 9— lateral view, 10— anterior view, 11— magnification of anterior pole; chorion sculpture with granules and tubercles, 12— micropylar process, with transverse constriction and circular apical opening.
