Diagnosis

Specimens of Schacontia medalba are most readily diagnosed from those of Schacontia chanesalis by male genitalia, specifically the reduced, unlobed valvae and the naked intrasaccular process, features they share with Schacontia umbra.

Re-description

(Fig. 1). Forewing length 6.5–1.0 mm. Head - Frons conical; labial palpi straight, extending as far as clypeus. Thorax - Female with one pair of hind tibial spurs (medial pair absent); legs uniform gray brown. Forewing. Basal area primarily gray brown, undivided; antemedial (am) line meets anal margin. Subterminal line interrupted by wing veins; medial area partially suffused with white, especially basad; white postmedial line appears shaded basally, interrupts/traverses dark shading between apical area and distal region of medial area; this “double” line faintly common to HW; FW fringe gray-brown. Hindwing. Postmedial line present, conspicuous (see above); terminal area lightly shaded, fringe white. Abdomen - Apical bands of pale scales on abdominal segments; terminal dots grayish brown, faint if present. Tympanal organs (Fig. 21). As for the medalba group, vide supra. Male genitalia (Figs 36, 37). Teguminal sulcus short, such that anterior margin of tegumen appears deeply invaginate; juxta U-shaped; valvae simple, reduced, rounded, not bilobed or emarginate; intrasaccular process a simple flange; intrasaccular process naked; phallus simple, cornuti absent. Female genitalia (Fig. 38). Antrum wider than deep, chalice-like; ductus bursae inconspicuous, no colliculum apparent; corpus bursae indistinct, weakly sclerotized, elongate.

Immature stages

Unknown.
Variation. Variable in size; forewings vary with respect to obfuscation in medial area.

Biology

Unknown.

Distribution
