Thoreyella maracaja Bernardes, Schwertner & Grazia, 2011

( Figs. 12 , 74–76 ; Tab. 2 )

Eggs with flat lateral walls, cross-section of chorion subquadrangular; light green prior to embryonic development; operculum subquadrangular and flat; chorion translucent and granulated, both at the lateral walls ( Fig. 12 ) and at the operculum. The eclosion line not evident under SM, and the AMPs are circularly arranged in a row around the anterior pole, translucent, long, and filiform ( Fig. 12 ).

The chorion surface appears mostly smooth under SEM but is clearly granulated at the lateral wall ( Figs. 74, 75 ). In the micrographs, the eclosion line is obscured, and the AMPs are apparently smooth ( Fig. 76 ).
