Diagnosis.
The species is characterised externally by the pale, greyish brown forewing with the fold and veins mottled with light brown. The male genitalia are distinguished in having a basally broad subtriangular vincular process in combination with a broad, inwardly curved sacculus. Similar species
S. gobica
Povolný, 1969
has both the sacculus and saccus slightly broader than the cucullus (compared with about twice as broad as the cucullus in
S. ravida
sp. nov.
);
S. caucasica
(
Povolný, 2001
)
differs in the longer and basally narrower sacculus, narrower vincular process and more slender phallus.
Description. Adult
(
Fig. 66
). Wingspan
14.4–14.8 mm
. Head, thorax and tegulae covered with grey browntipped scales, frons light grey to white, labial palpus upcurved, brown mixed with grey, palpomere 2 grey on inner and upper surface, scape brown mottled with grey, flagellomeres brown grey ringed. Forewing covered uniformly with pale brown-tipped scales, diffuse greyish black streak in fold, cilia grey brown-tipped. Hindwing and cilia light grey.
Male genitalia
(
Figs 126, 127
). Uncus twice as long as broad at base, weakly narrowed apically, posterior margin rounded; gnathos long, slender, weakly curved; tegumen moderately elongate, anteromedial emargination from 1/4 to 1/3 length of tegumen; cucullus gradually curved, narrowest in medial 1/3, apex broadened, extending to top of uncus; sacculus twice as broad as cucullus in middle and 1/4–1/3 length of cucullus, of even width, inner margin nearly straight, outer margin rounded in distal half, with short inwardly curved pointed tip; vinculum twice as broad as long, anteromedial emargination V-shaped, vincular process subtriangular, at base as broad as sacculus, strongly narrowed towards rounded apex with outwardly curved pointed tip; saccus slender, pointed or weakly rounded apically, extending beyond top of pedunculus; distal portion of phallus moderately broad, parallel-sided, apex weakly pointed, apical arm slender, distinctly sinuate, caecum strongly inflated, about half length of phallic tube.
Variation. Two specimens slightly vary in the shape of the uncus, being narrowed either in the distal 1/3 or distal 1/2; saccus varies in length, slightly or distinctly extending beyond the top of the pedunculus.

Etymology.
The species name is derived from the Latin “
ravidus”
meaning grey, referring to uniformly grey forewing of the new species.
