Sigara (Tropocorixa) denseconscripta

( Fig. 11 )

Chorionic surface densely and finely pored, with tubular projections with (usually 2) or without apical ramifications, delimiting small areas (polygonal units?). Within each area it presents 1–3 of these projections. A nipple structure occurs on the anterior micropylar area.

Additional data. Shape oval; color yellow; flattened at one side, with a very short stalk.
