Figures 5, 6, 19–22

DIAGNOSIS: The egg of S. pectoralis is somewhat oval in shape as seen in dorsal and ventral views (figs. 5, 6) and not linear (parallel sided) like that of T. angustula . It is also larger in size, but the anterior end is somewhat larger than the posterior end, as true for T. angustula .
