Etymology. The specific epithet is dedicated to Marek Dvořák (Smrčná, Czech Republic), a well-known collector of Noctuidae   and friend of the authors.

Diagnosis. Lasianobia dvoraki   ( Figs 1–4 View FIGURES 1–8 ) is externally most similar to L. labranga   sp. nov. ( Fig. 9 View FIGURES 9–12 ) and L. fickleri   ( Fig. 8 View FIGURES 1–8 ), but differs from L. labranga   in having a smaller reniform stigmata with a shorter extensions along the cubital veins; and from L. fickleri   in its slightly larger size, broader forewings, slightly thinner submedial longitudinal dash, the paler, whitish orbicular and reniform stigmata not fused along the cubital vein, smaller reniform stigma with shorter extensions along the cubital veins, and the darker, grayish brown hindwings. In L. fickleri   , the forewing is broader, the submedial longitudinal dash slightly broader, the orbicular and reniform stigmata are pale brown and fused along the cubital vein, the reniform stigma is broader, and with significantly longer extensions along the cubital veins; the hindwings are lighter, pale brown. The male genitalia of L. dvoraki   ( Figs 13–16 View FIGURES 13–16 ) are similar to those of L. labranga   ( Fig. 20 View FIGURES 20–22 ), L. albilinea   ( Figs 17–19 View FIGURES 17–19 ) and L. superba   ( Fig. 21 View FIGURES 20–22 ), but differ from L. labranga   ( Fig. 20 View FIGURES 20–22 ) in the slightly weaker digitus, the presence of a broad cluster of spinules on the 1 st medial   ventral diverticulum of the aedeagus vesica, the smaller 2nd medial ventral diverticulum, and a shorter distal section of the vesica; from L. albilinea   ( Figs 17–19 View FIGURES 17–19 ) they differ in having the uncus less narrowed basally, broader penicular lobes, shorter and weaker digitus, slightly weaker distal saccular process, more robust carinal thorn of the aedeagus, presence of subbasal ventral cluster of spinules, broader 1 st medial   ventral diverticulum armed with a broader cluster of spinules, shorter distal section of the vesica, and smaller, row-like distal cluster of spines (while in L. albilinea   this cluster is broad and encircles the dorsal surface of the vesica). From L. superba   ( Fig. 21 View FIGURES 20–22 ) they differ by having an uncus narrower basally, slightly broader cucullus, absence of an ampulla on the costa, somewhat shorter distal saccular process, shorter aedeagus with more robust carinal thorn, presence of subbasal dorsal cluster of spinules, larger cluster of spinules on the 1 st ventral   medial diverticulum, the 2nd ventral medial diverticulum with no spinules, shorter distal section of the vesica, and the larger distal cluster of spinules.

Molecular analysis. Barcodes for twelve L. dvoraki   showed 0.0–1.1% divergence. Pairwise comparisons between L. dvoraki   and the holotype of L. labranga   differ by 4.2–4.4%. Four specimens of L. albilinea   differ from L. dvoraki   by 3.9–4.4%, anddifferences between L. dvoraki   and two specimens of L. superba   were 3.0–3.2%.

Description. Adult ( Figs 1–4 View FIGURES 1–8 ). Forewing length 12–15 mm in males. Male antennae bipectinate, grayish brown. Coloration of body and forewings reddish brown, in some specimens with intense gray suffusion. Forewing ground colour somewhat darker than thorax, with intense pale gray suffusion along the costa; subbasal line absent; ante- and postmedial lines thin, brown, curved; submedial longitudinal dash thin, creamy yellowish, outlined with fine black scales, slightly curved; subterminal line thin, yellowish creamy, angled at apex; terminal line interrupted into a row of brown dots between veins; orbicular stigma small, rounded, yellowish creamy; reniform stigma with short trigonal extensions along the cubital veins; cilia grayish brown. Hindwing dark brownish gray, slightly lightened basally; discal spot short, semilunar, diffuse; cilia dark grayish brown. Male genitalia ( Figs 13–16 View FIGURES 13–16 ): Uncus dorso-ventrally flattened, broad, trapezoidal, with distally rounded corners, weakly hairy; tegument relatively short but broad; penicular lobes broad, ear-shaped; juxta elongated, conical in shape; vinculum V-shaped, with rounded apex; valves symmetrical, evenly curved medially; costa heavily sclerotized; costal margin evenly curved, heavily sclerotized; digitus large, its base broad, distally narrow, apically tapered; cucullus narrow, trigonal with rounded corners, weakly setose; neck of cucullus elongate, narrow; sacculus well-developed, broad, its dorsal surface with short rounded protrusion medially; distal saccular process robust, long, peak-shaped, with broad basal plate; clasper short, trigonal with no processes; aedeagus short, broad, cylindrical; carina with trigonal thorn; vesica tubular, its middle section curved dorsally; subbasal section with two band-like clusters of robust spinules dorsally and ventrally; 1 st medial   diverticulum short and broad, armed with a broad cluster of short spinules; 2nd medial diverticulum small, conical, with no spinules; subapical diverticulum broad, short, with band-like cluster of short but robust spinules.

Female unknown.

Bionomics and distribution. Twelve males were collected at ultraviolet light in May 2016 in remote parts of the southwestern part of China’s Sichuan Province, near Litang and Daocheng (Fig. 31). Specimens of the new species were collected at altitudes ranging from 4000 to 4100 m in mountainous mixed forests dominated by various conifers, rhododendrons, and various shrubs.
