(Figs. 4A–F, 9G, 10G, 11K, 12K, 13K)

Description. Length of male 4.41 mm. General appearance brown. Crown 1.4 x longer than basal width between eyes, light brown, with two pale white longitudinal bands in center, separated by black line extending to two-thirds of crown length; after this, bands merge into a single band at apex (Fig. 4A). Face entirely black, with two transverse white bands in shape of inverted V at apex of frontoclypeus (Fig. 4C), and faint white band on outer margin of gena extending to eye. Forewings light brown; anteapical cells with dark spots and macula in discal cell, with 2 circular white spots in clavus, and 6–7 veinlets (Fig. 4B); veins dark brown. Legs with femora black, anterior and middle tibiae light brown, posterior tibiae black. Tarsi light brown.

Male genitalia. Pygofer in lateral view triangular, apex rounded; multiple macrosetae at apex (Fig. 9G). Subgenital plate triangular, much wider at base than apex, almost as wide as long, with row of thin, elongated setae at apex (Fig. 10G). Connective in ventral view straight in middle and slightly elevated toward junction with styles (Fig. 4D). Style in ventral view with apophysis short, robust, with no spines, square-shaped on inner margin; space between preapical lobe and apophysis C-shaped. Paraphyses in ventral view fused at base, diverging widely and abruptly beyond midlength (Fig. 4D). Aedeagus very short, L-shaped in lateral view (Fig. 4E); preatrium absent; dorsal apodeme longer than shaft, with slight curvature toward apex (Fig. 4E); shaft in lateral view straight and tubular, in apical view in gonopore area with two small lateral spines and third, larger dorsal spine (Fig. 4F). Gonopore subapical, at base of dorsal spine.

Diagnosis. Connective straight in middle and slightly elevated toward junction points with styles (Fig. 4D); straighter and less curved than in S. cyma . In dorsal view style apophysis without spine on inner margin; apophysis in ventral view square-shaped; paraphyses in dorsal view fused at base, diverging widely and abruptly beyond midpoint of their length, giving appearance of inverted U (Fig. 4D).
