Cryphia orthogramma Boursin, 1954 , Zeitschrift der Wiener Entomologischen Gesellschaft 39: 81, pl. 5, figs 1–4, pl. 6, figs 17, 18. Type locality: [ Russia] Siberia, Irkutsk.

Diagnosis. The species can be separated from the externally somewhat similar species of the genus Bryoleuca Hampson, 1908, B. granitalis (Butler, 1881) , B. albimixta (Sugi, 1980) , B. parva (Sugi, 1980) and B. volodia sp. n., by the on average narrower forewings with almost straight antemedial line running rather perpendicular to inner margin stigmata, less distinctly marked postmedial line and smaller, more obsolescent reniform stigma; the hindwings are ochreous-greyish, paler than those of B. granitalis (Butler, 1881) and B. albimixta (Sugi, 1980) . The male genitalia of B. orthogramma differ from those of the other species of the lineage by the more slender, distally not dilated uncus and the broadly shield-like (not subdeltoidal or rounded) juxta. The ampulla is remarkably shorter than B. granitalis , B . albimixta and B. parva ; the long, apically pointed and not serrate-dentate cornutus and the relatively short ampulla are shared features with B. volodia .

Distribution. The species is widespread in the northern steppe belt of Eurasia, from Eastern Europe to the Russian Far East, the Korean peninsula and Japan; a different subspecies (ssp. taishanensis Boursin, 1954) occurs in Central China.
