Diagnosis. Scrobipalpa ferruginosa is defined externally by the light brown forewing with a dark costal margin and ochreous-brown head (Figs 45, 46). The male genitalia are characterised by the comparatively short and narrow weakly curved inwardly sacculus in combination with the nearly parallel-sided saccus, and cucullus distinctly broadened apically (Fig. 103). Scrobipalpa alterna Falkovitsh & Bidzilya, 2006 and S. lutea Povolný, 1977 are somewhat similar but the saccus is weakly curved inwardly, the vincular process is shorter and the cucullus is not broadened apically. The female genitalia of S. ferruginosa (Figs 148–150) are similar to those of S. pseudolutea Piskunov, 1990 and S. pauperella (Heinemann, 1870), but slightly differ in the shorter sternite VIII and shape of the signum.

Male genitalia (Fig.103). Uncus slightly longer than broad, weakly narrowed apically, posterior margin rounded; gnathos short, slightly curved; tegumen elongate, with broadly rounded anteromedial emargination extending to 1/4 as broad as cucullus, weakly narrowed posteriorly, with inwardly curved short tip; vinculum twice as broad as long, with V-shaped posteromedial emargination, vincular process subtriangular with outwardly curved tip, as broad at base as sacculus; saccus narrow, distal portion nearly parallel-sided, weakly extending beyond top of pedunculus; distal portion of phallus straight, with weakly pointed apex, apical arm narrow, weakly sinuate, caecum about as broad and half as long as phallic tube.

Molecular data. No barcode available.

Distribution. Russia: Buryatia (new record), Zabaikalskiy krai (Povolný 2001: 187); Mongolia (new record).

Remark 1. Euscrobipalpa ferruginosa was described from a single specimen (Fig. 45) collected in the vicinity of Nizhniy Tsasutchey village, Zabaikalskiy krai, Russia. The holotype proved to be female (frenulum consisting of three acanthae), its genitalia were erroneously placed under the male paratype of S. bidzilyai, whereas the male genitalia of the latter species were assigned to S. ferruginosa and figured in the original description (Povolný 2001: 186, fig. 7). The female genitalia of the holotype of ferruginosa which were treated as a female of S. bidzilya (Povolný 2001: 185, fig. 5), are conspecific with the holotype of S. pinosa (Fig. 149), which was described from a single female (Fig. 46) collected sympatrically with S. ferruginosa. The holotype of S. pinosa is also indistinguishable from the holotype of S. ferruginosa (Fig. 45). Both species were described in the same paper, on page 187 (S. ferruginosa) and on page 194 (S. pinosa). Hence we consider here S. pinosa (Povolný, 2001) a syn. nov. of S. ferruginosa (Povolný, 2001).

Remark 2. The male genitalia of S. ferruginosa are described here for the first time.
