( Figs 8 , 36 )

Miltochrista hololeuca Hampson, 1895: 296 . Type locality: “ Bhután ”.

Type material examined. HOLOTYPE (by monotypy) ( Figs 8 , 36 ): ♂, “ Bhutan. / 95–37. [printed] / May [18]94 [handwritten]” // “ Miltochrista / hololeuca / type ♂ Hmpsn.” (handwritten) // round printed label with a red circle “ Type ” / printed label with QR-code “NHMUK010604597”, slide BMNH(E) Arct. 6580♂ Volynkin ( NHMUK).

Diagnosis. Forewing length is 16 mm in male. Externally, B. hololeuca ( Fig. 8 ) differs from B. flavicollis ( Fig. 9 ) in shorter lamellae of its antennae, white patagia (ochreous yellow in B. flavicollis ), paler, white forewings, and shorter blackish basal area of forewing costa. Barsine hololeuca differs from B. laszloi ( Figs 10–12 ) in its shorter blackish basal area of forewing costa and slightly more elongated forewing apex. In the male genitalia, B. hololeuca ( Fig. 36 ) differs from B. flavicollis ( Fig. 37 ) in its broader valva, slightly shorter and apically blunt medial costal process, shorter and broader, almost trigonal basal saccular process (narrow and elongated, blade-shaped in B. flavicollis ), broader, shorter and less curved distal saccular process, larger 1 st medial diverticulum, and longer and distally narrower 3 rd medial diverticulum. The differences from B. laszloi are listed in the diagnosis of the latter.

Female is unknown.

Distribution. Barsine hololeuca is to date known only from the holotype collected in Bhutan ( HAMPSON 1895). The record from China (Yunnan) ( FANG 2000) needs confirmation.
