( Figs 51 , 87 )

Type material. Holotype ( Figs 51 , 87 ): male, “ Vietnam, Prov. Tuyen Quang | Na Hang Nature Reserve , 300 m | 105°5'E, 22°3'N, 22.II.–5.III.1997 | leg. G. Csorba ” / “Slide | CW 00099 ♂ [prepared by A. Volynkin]” ( MWM / ZSM).

Diagnosis. The forewing length is 13.0 mm in the male holotype. Dubatoloviana vieta sp. n. differs externally from the closely related D. navneetsinghi and D. fumidisca in the longer and narrower forewing with a more intense greyish-brown subterminal suffusion at the anal corner. The male genitalia of D. vieta sp. n. are most similar to D. fumidisca but can be distinguished by the longer, narrower and straighter uncus, the slightly shorter valva with a narrower cucullus and a proximally narrower distal saccular process. Additionally, the vinculum of the new species is longer than in the similar congener.

Distribution. The new species is currently known only from its type locality in Northern Vietnam (Tuyen Quang Province). The record of ‘ Eilema trimacula Holloway’ from Laos (Kishida 2020) probably also belongs to D. vieta sp. n. but requires confirmation.

Etymology. The specific epithet is derived from the Viet people native to modern-day Northern Vietnam and Southern China. The name is a noun in the nominative singular.
