Studies on the chorionic structure of the eggs of Corixoidea (Hemiptera: Heteroptera) with scanning electron microscopy Author Konopko, Susana Amanda Author Mazzucconi, Silvia Ana Author Ruf, Monica Lopez text Zootaxa 2013 3737 3 223 240 journal article 10.11646/zootaxa.3737.3.2 30503c49-5e46-4768-a1a8-54f08f876c1f 1175-5326 220838 B3CBE9FA-BF92-475D-9BF4-1E2B3DF439C3 Sigara (Tropocorixa) santiagiensis ( Figs. 14–15 ) Chorionic surface densely and finely pored, with polygonal units delimited by slightly distinguishable edges not raised from the surface ( Fig. 14 ). Within each unit there are numerous small equidistant protuberances ( Fig. 14 ). A nipple structure occurs on the anterior micropylar area, surrounded by a lamellated zone with a circular design ( Fig. 15 ).
