External egg structure of the Pentatomidae (Hemiptera: Heteroptera) and the search for characters with phylogenetic importance Matesco, Viviana Cauduro Bianchi, Filipe Michels Fürstenau, Brenda Bianca Rodrigues Jesse Silva, Priscila Poock Da Campos, Luiz Alexandre Grazia, Jocelia Zootaxa 2014 2014-02-26 3768 3 351 385 Stal, 1860 Stal 1860 [151,456,1509,1535] Insecta Pentatomidae Banasa Animalia Hemiptera 17 368 Arthropoda species induta  ( Figs. 10, 66–69; Tab. 2)  Eggs barrel-shaped; brown prior to embryonic development; operculum round and convex; chorion light brown, almost translucent, and reticulated ( Fig. 10). The eclosion line is evident under SM, as a smooth paler band delimited by the AMPs ( Fig. 10). The aero-micropylar processes are circularly arranged in a row around the anterior pole, white, short, and clubbed ( Fig. 10). The chorion surface is reticulated under SEM, but the sculpture pattern may be obliterated in some portions of the egg ( Fig. 66). Remnants of adhesive material are evident at the posterior pole; at the lateral wall, the sculpture pattern is clearly altered in the area where the egg was fixed to another in the egg mass ( Fig. 66). Most of the chorion is recovered by shallow cells with irregular edges forming truncated rough masses. The operculum is similarly sculptured ( Fig. 67). The eclosion line is evident as a broad depressed band, in which there are smaller rough masses, more widely spaced near the AMPs ( Fig. 68). The AMPs are moderately short and distinctly clubbed, with circular and apical openings ( Fig. 68). Their surface is clearly spongy under higher magnification ( Fig. 69).
