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).
