( Figs 1–4 )

Materials Examined. Holotype. Male, Lulang, Linzhi , Xizang, 26.VII.2013, HL Han & ZG Wu. Paratypes . 1 male & 1 female, Nadengzuo, 2700 m, Linzhi , Xizang, 17.VIII.2014, Huilin Han ; 2 males, with the same data as the holotype. The type specimens are deposited in the collection of Northeast Forestry University, Harbin , China ( NEFU).

Diagnosis. Meganola tibetensis is somewhat reminiscent of Porcellanola species on external appearance ( Figs 1 & 5 ), but male genitalia clearly indicate that this species belongs to Meganola . Main differences on forewing compared with M. mediofusca are as follows: terminal area reddish brown, subterminal area brown and middle area grey white in new species ( Figs 1 & 3 ), while terminal area brown, subterminal area grey white and middle area blackish brown with grey white in M. mediofusca ( Figs 7 & 9 ).

Description. Adult ( Figs 1 & 3 ). Wingspan 22–28 mm. Head, collar and tegula white; antennae brown, bipectinate in male, filiform in female. Thorax covered with whitish hair like scales. Abdomen grayish white with yellowish brown. Basal line undistinguished, but showing a black stripe in forewing base; antemedial line black, represented by a big quadrangular spot at anterior part, zigzag at posterior part; medial line black, a small dot before discal cell, then straight inwards to inner margin; postmedial line black, waved, parallel to subterminal line; subterminal line black, waved; a row of grey-black and clathrate scales on outer margin; terminal area reddish brown; subterminal area and posterior part of posterior part area brown. Hind wing ground colour grey; veins highlighted. Male genitalia ( Fig 2 ): Uncus strong, sharp at apex; tegumen medium-long; valva slightly incurved, medium-long, with hairs apically, a cluster of thick, stiff and hardly sclerotized hairs medially; harpe approximate trapezoid, slightly sclerotized; juxta round; saccus relatively long, broad V-shaped. Aedeagus thin and long; vesica without cornuti. Female genitalia ( Fig 4 ): Papillae anales conical; apophyses posteriores medium-long, well developed; apophyses anteriores short, 1/2 time as long as apophyses posteriores; ductus bursae almost 2 times as long as corpus bursae, sclerotized medially; corpus bursae relatively small, elliptical-ovoid, membranous, with two spinulose signas.

Distribution. China (Tibet).
