Figs. 2b , 4 c-d, 5q

Material examined: Holotype ♂, BRAZIL: Rondônia (RO), Cacaulândia , 140 m, xi.1991 (Becker 79657) ; Paratypes: 2 ♀♀, 1 ♀, same data as holotype, g. s. 5744 ( VOB) .

Diagnosis. Medium size.FW length 12-15 mm (28-34 mm wingspan). Pale fuscous. FW 14-15 (32-34 mm wingspan), crossed with faint, curved lines; apex acute.

Description ( Fig. 2b ): Sexes similar.Male FW length 12 mm (28 mm wingspan); female 15 mm (34 mm wingspan). Pale fuscous. Labial palpi fuscous dorsally, white ventrally. Legs pale fuscous, white ventrally. FW dorsally with antemedial band, faint, curved; postmedial faint, curved from costa to M3, straigh to dorsum; reniform diffuse; cilia fuscous; pale fuscous underside. Abdomen whitish ventrally.

Male genitalia ( Figs. 4c ): Uncus nearly as long as valva, slightly constricted along middle, apex round; valva three times as broad as long, margins nearly parallel, evenly curved dorsad; pair of long, curved. thin, sharp pointed fibulae. Juxta a small shield, forked as pair of thin, sharp pointed prongs posteriorly. Vinculum expanded basally, as long triangle.Phallus ( Fig.4d ) straight, short; vesica with a long, thin, twisted cornutus, almost as long as phallus.

Female genitalia ( Fig. 5q ): Ostium bursae short, narrow; antrum bulbose; ductus bursae very long, coiled; corpus bursae spherical, signum a large, spined plate.

Distribution: Known from the type-locality only.

Etymology: From the Latin soror =sister, in reference to its similarity to S. belialis (Walker) .

Remarks: Very similar to S. belialis (Walker, 1864) , both in size and shape, except for the ground color more yellowish. Externally almost identical to Patania surinamensis (Sepp, [1846]), from which it differes by the faded, almost absent markings on FW.
