Diachrysia witti Ronkay, Ronkay & Behounek, 2008 , The Witt Catalogue 1: 32, plate 5, figs 3–4, plate 40, figs 7–9, gen. fig. 18. Type locality: Russia, Vladivostok.

Synonymy. Diachrysia bieti sensu auctorum, nec Oberthür, 1884 (Ronkay et al. 2008).

Diagnosis. The species is rather remote within the entire chryson -lineage (Ronkay et al. 2008). It can be distinguished easily from the other members of the D. leonina-D. bieti lineage by its dark grey-brown ground colour with fine golden-bronze sheen, well-defined antemedial, medial, postmedial and subterminal crosslines and the uniformly darkened hindwing. The distinctive features of the male genitalia, in comparison with D. leonina , D. oberthueri , and D. bieti , are the longer, stronger uncus, the more rounded, medially broadest valvae, the much shorter vinculum, the reduced terminal cornutus; those of the female genitalia are the more or less straight ductus bursae and the rather short, elliptical-ovoid corpus bursae.

Distribution. A Sino-Pacific species, occuring in the temperate parts of the Pacific region (Russian Far East: Primorye, Korea, Japan, north-east China) and in the Central Chinese mountains in Shaanxi (Ronkay et al. 2008).
