Sigara (Tropocorixa) schadei

( Figs. 16–17 )

Chorionic surface densely and finely pored, with tubular projections with apical ramifications (usually more than 2), delimiting small areas (polygonal units?) ( Figs. 16–17 ). Within each area it presents 1–3 of these projections. A nipple structure occurs on the anterior micropylar area ( Fig. 16 ).
