Synonymies (for more details on nomenclature see Scoble 1999): Acidalia sulphuraria Freyer, 1847 ([Russia]: Sarepta [Krasnoarmeysk]).

For the list of unavailable names, see Hausmann (2004).

Material examined: 2 ♁/ ♀ (see appendix).

Diagnosis. Wingspan ♁ ♀ 22–24 mm (Hausmann 2004). Ground colour creamy yellowish- to reddish-white, strongly pronounced transversal lines and dark suffusion in the medial area. (Plate 8, Figs 14–15). Scopula albiceraria, if present in Iran (see Remarks), can externally be confused only with S. immistaria. A diagnosis can be made with certainty based on the genitalia characters.

In the male genitalia 8th sternite basally notched, laterally concave, cerata short, broad (basally notched, broad, cerata medium sized and thin in S. immistaria) (see Plate 18, Figs 5–6).

In the female genitalia antrum with small v-shaped sclerite (with very small notched sclerite in S. immistaria) (see Plate 26, Figs 3–4).

Phenology. Bivoltine species, flying from early June to late August (Hausmann 2004).

Biology. Unknown.

Habitat. In Europe at altitudes from 0 m to 300 m, and Asia from 500 m to 1700 m (Hausmann 2004). Investigated specimens from Mongolia were collected from 774 m to 2900 m.

Distribution. Southeastern Russia, Urals, Mongolia (Hausmann 2004). Turkmenia, Kazakhstan and southern Siberia (Viidalepp 1996; Hausmann 2004; Makhov 2023). The occurrence in the Caucasus, Transcaucasus questionable (Hausmann 2004).

Remarks. Prout (1912 –1915) reported this species as an element for the Iranian fauna. Though during our investigation no specimens from Iran could be traced. It can be assumed that this species does not occur in Iran, and the report is probably due to confusion with S. immistaria.

DNA-barcoding. Nearest species: S. latelineata (Graeser, 1892) with 1.8 % (see Supplementary Table S1).
