Description. Body straminous to brownish with white reticulate and brownish irrorate markings. Head slightly wider than pronotum. Crown brownish yellow, with a median circular white spot on anterior margin and four white patches on the posterior margin. Anterior margin of head ochraceous with brownish irrorate markings. Compound eyes reddish brown, ocelli yellowish-white. Pronotum wider than long, ochraceous with white reticulate and dark brown wavy markings, anterior margin with a row of small white spots. Mesoscutum brownish, with a pair of median white irregualr spots, lateral margins with white and black alternate stripes. Scutellum brownish yellow, triangular, with a narrow median longitudinal brownish stripe, lateral margins with white and black transverse stripes, posterior margin with a small white spot. Forewings macropterous, straminous with white reticulate and brownish irrorate markings, apical cells with brown speckles, appendix narrow, venations pale orange-yellow, with three anteapical cells, inner anteapical cell opened at base, false veins present. Legs brownish yellow, unmarked, except for darker bases of macrosetae.
Male genitalia. Male pygofer in lateral view longer than wide, broadly rounded, with posterodorsal margin subtriangular, with several rows of stout setae at dorsal margin on distal 1/3. Valve wider than long, broadly triangular. Subgenital plate subrounded, with narrow and elongated finger-shaped apex, with basolateral uniseriate row of macrosetae. Style linear, slightly wider at base with lateral process, preapical lobe not prominent. Connective Y shaped, stem longer than arms. Aedeagus narrow and elongated, nearly twice the length of aedeagal shaft, converged, slightly wider at base with pointed apex, curved in lateral view. Aedeagal shaft V-shaped, stout and tubular, wider then aedeagal processes with pointed and inward apex, diverged in ventral view; gonopore subapical on the lateral margin of each shaft.
Measurements. Body length. Male 4.4–4.5 mm; female 4.4–4.6 mm.
Type material. Holotype: ♂, CHINA: Guizhou Province, Guiyang City, Huaxi, 8 June 2022, coll. Wenjun Cao (GUGC); paratypes: 8♂♂, 7♀♀, same as holotype.
Remarks. The aedeagus of this new species is very similar to that of species belonging the related opsiine genus Litura Knight, 1970, which also have the aedeagal processes elongated and well separated from the shafts. However Litura differs in having a rhomboid transcommissural mark on the forewings. The new species closely resembles S. chajingensis but differs in having aedeagal processes nearly twice the length of aedeagal shaft, converged, slightly wider at base with pointed apex, curved in lateral view and widely separated from the aedeagal shaft; and the aedeagal shaftst forming a V in posterior view, stout and tubular, wider than the aedeagal processes with pointed and inward apex, diverged in ventral view.
Etymology. The species name “ discedens ” is derived from the Latin word, which means separated or scattered, referring to the protruded aedeagal shaft and more dispersed basal processes of aedeagus.
Distribution: Oriental. China (Guizhou).
