Description. Adult. Colouration ( Figs 1 View Figure , 6). Body dark brown to black, intersegmental membranes yellow to yellowish brown. Compound eyes dark reddish brown, ocelli reddish. Antennal segments 1¯2 and 8¯10 dark brown to black, segments 3‒6 dirty yellowish, segment 7 brown. Forewing opaque, irregularly dark brown to black. Hindwing semitransparent, brownish, with brown veins C+Sc, R+M+Cu, R, M+Cu, M, A1, A2 and brown clavus. Legs black, femora and metatibia brown. Younger specimens with less expanded dark colour.

Structure. Head ( Figs 3 View Figure , 14 View Figure ) with vertex 0.5 times as long as wide; genal processes irregularly conical, subacute apically, 0.4 times as long as vertex along midline, contiguous medio-basally. Antenna 0.9‒1.0 times as long as head width; segment 3 subequal in length to combined length of segments 4 and 5; segments 5, 7‒10 subequal in length; terminal setae 0.8 and 0.5 times as long as segment 10, respectively. Forewing ( Figs 2 View Figure , 6) 3.2‒ 3.7 times as long as head width, 1.9‒2.0 times as long as broad; fore margin straight, apex broadly rounded; vein C+Sc mostly straight, weakly curved in apical quarter, slender; cell c+sc relatively broad; vein Rs weakly sinuous, curved towards fore margin apically; vein M strongly curved; cell m1 value 0.8‒1.0, relatively large, subtriangular; cell cu1 value 1.3‒1.6, relatively large, subtrapezoidal; surface spinules very densely spaced, covering membrane in all cells up to veins (Fig. 5). Metatibia 0.8‒0.9 times as long as head width. Male and female terminalia as in Figs 16‒23 View Figure . Male proctiger with basal and distal portion subequal in length. Ventral margin of subgenital plate slightly angled, in profile, covered in long, relatively sparse setae in the middle, laterally and ventrally, as well as apically. Paramere lamellar, slightly constricted in basal third, evenly narrowing in apical third towards blunt apex; outer face sparsely covered in long hairs in apical half and along hind margin; inner surface with a strongly sclerotised hook, pointing to the rear, in apical third along fore margin, and with a strongly sclerotised transverse ridge in apical third, with some long setae along the margin in apical quarter, a group of slightly thicker and denser but shorter setae just basad of transverse ridge and a narrow band of fine, sparse setae in the middle. Distal segment of aedeagus consisting of a tubular basal half and a club-shaped apical half. Female proctiger 1.0 times as long as head width; dorsal outline weakly concave; apex subacute; circumanal ring 0.3 times as long as proctiger; with a row of moderately long setae around circumanal ring, sparse very long, fine setae in the middle and short setae apically. Subgenital plate cuneate, irregularly tapering, apex pointed; ventral margin, in profile mostly straight, slightly up-curved in apical quarter; covered in long setae except for apex where the setae are short. Dorsal valvula cuneate; lateral valvula narrowly rounded apically; ventral valvula straight, simple without apical teeth.

Measurements (3 ♂ / 3 ♀; in mm). Head width 0.61¯0.63/ 0.65¯0.66; vertex width 0.36/ 0.39; antennal length 0.58¯0.60/ 0.61¯0.64; length of first antennal flagellomere 0.05¯0.06/ 0.05¯0.06; forewing length 1.88¯1.97/ 2.38¯2.47; length of vein Rs 0.88¯0.94/ 1.13¯1.29; metatibia length 0.49¯0.53/ 0.52¯0.55; male proctiger length 0.30¯0.36; paramere length 0.25¯0.27; length of distal segment of aedeagus 0.20¯0.22; female proctiger length 0.65¯0.69; length of circumanal ring 0.17¯0.19; female subgenital plate length 0.47¯0.56.

Fifth instar immature unknown.

Etymology. From Latin furvus = dark-coloured, black, referring to the dark body colour.

Distribution. South Korea (Gangwon-do).

Host plant. Adults were collected on Morus australis Poir.  ( Moraceae  ) which is a likely host.
