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 ).
