Mormidea cornicollis Stål, 1860

( Figs. 4, 5 View FIGURES 1 – 12 , 43–46 View FIGURES 37 – 48 ; Tab. 2 View TABLE 2 )

Eggs barrel-shaped; light yellow prior to embryonic development; operculum round and convex; chorion translucent and spinose ( Fig. 4 View FIGURES 1 – 12 ). Eggs darker, with two irregular red stripes and red eyes evident in anterior view after embryonic development ( Fig. 5 View FIGURES 1 – 12 ). The eclosion line not evident under SM, and the AMPs are circularly arranged in a row around the anterior pole, white, and moderately long ( Figs. 4, 5 View FIGURES 1 – 12 ).

Under SEM, the chorion surface is spinose, and the spines are short. The interconnected spines form faintly distinct polygonal markings at the lateral wall; the sculpture pattern is altered where the eggs were attached to another ( Fig. 43 View FIGURES 37 – 48 ). The operculum is similarly sculptured, displaying spines of different sizes, and the polygonal markings are especially apparent ( Figs. 44, 45 View FIGURES 37 – 48 ). The eclosion line is not discernible. The AMPs are slender, only slightly clubbed, and bear circular and apical openings ( Fig. 46 View FIGURES 37 – 48 ). Their surface is clearly spongy under higher magnification ( Fig. 46 View FIGURES 37 – 48 ).
