Diagnosis. Very similar to M. sinjaevi but can be distinguished by the following characters: wings pale grayishyellow; forewing broader with apex less produced.

Taibaishan, 1500 m, 33˚50’N, 107˚41’E, April 2005, Viktor Sinyaev & his team leg. (MWM); [SICHUAN]. Gonggashan Mountain: 1 male (paratype), 29°41′N, 101°58′E, 2200 m, 25.V–8.VI.2001, V.

XVIII. Comparmustilia Wang, X. & Zolotuhin, gen. nov. ( FIGURES 30–32 )

Type species: Mustilia sphingiformis Moore, 1879 , Proc. Zool. Soc. London: 407, by present designation.

Diagnosis. Characterized by the following features: uncus bifid, lobes pointed and apically outcurved; a strumae present at the near the apex of valve; posterior margin of 8th sternite with V-shaped invagination; wings strongly falcate, somewhat resembling hawkmoths.

Description. Male. Head brown ochre; basal half of antenna pectinate, distal part filiform; proboscis short.

Thorax. Dark ochre mixed with gray hairs; forewing purplish-brown except for a broad dark brown crescent,on the outer margin; long and narrow, apex strongly produced, outer margin below apex slightly concave; antemedial line arched; medial line obscure; postmedial line straight; submarginal line angled at M2, straight either side; hindwing with postmedial and submarginal lines almost straight.

Abdomen. Dark ochre with yellow stripes.

Male genitalia. Uncus bifid, lobes pointed and apically outcurved; gnathos a pair of long, curved, posterior directed processes; valva with a warty protuberance near apex, apex blunt with long hairs; saccus broad and short; aedeagus slightly curved near apex; vesica with numerous small cornutispinules; posterior margin of 8th sternite with V-shaped medially invagiation; 8th tergite bell shaped.

Female. Similar to male, but larger and with filiform antennae.

Female genitalia: apophyses posteriores longer than apophyses anteriores slender, with rounded tips; antrum membranous; ductus bursae sclerotized; corpus bursae oval with signum lacking.

Etymology. From the Latin compar (= comparable) plus the genus name Mustilia , referring to the establishment of the genus based on comparing it to the genus Mustilia , in which the type species of this new genus was previously included.

Distribution. Himalayan region.

Remarks. Although the type species, Mustilia sphingiformis , was described by Moore (1879) in Mustilia , it is very different from the other Mustilia species based on the following characters: uncus much narrower with lobes outcurved apicaly; valve broad with a warty protuberance near apex; posterior margin of 8th sternite with a narrow V-shaped notch. On the basis of these shared characters, we here establish a new genus including three species, all of which are recorded from China (Map 18).
