( Figs 21, 22 , 117, 118 )

TL: Darjeeling [West Bengal, India]

= Icambosida dorsalis Moore, 1888: 394 (TL: Dharmsala [Dharamshala, Himachal Pradesh, India])

Material Examined: India, Mizoram: [Aizawl district], Reiek , 3 ♂, 20.iv.2017, H. Singh leg. ( NZCZSI; 12838/ H10) ; West Bengal: [Kalimpong district], Jhandi , 4 ♂, 10.ix.2018, H. Singh leg.

( NZCZSI; 12839/H10) ; Himachal Pradesh: [Solan district], Solan , 1 ♂, 26.ix.1991, A.P.S. Kaleka leg. ( NZCZSI; 12841/H10) ; Uttarakhand: [Chamoli district], Bamiyala , 1 ♂, 3.viii.2016, S.S. Bisht leg. ( NZCZSI; 12840/H10) .

Diagnosis: Forewing Length: ♂ 17.5 mm. Externally, L. (T.) rubidorsa ( Figs 21, 22 ) is closely similar to roughly thirteen species which share pure white wings with greyish or blackish maculation and reddish abdomen with variable pattern of black spots or bands on it. However, L. (T.) rubidorsa is easily separable from its closely similar congeners by the red colour of foreleg femur and immaculate red abdomen. In male genitalia, L. (T.) rubidorsa ( Figs 117, 118 ) is closely similar to L. (T.) obliquivitta ( Figs 115, 116 ). The diagnosis is discussed under L. (T.) obliquivitta .

Distribution. Indian records: Assam, West Bengal (Darjeeling), Indian Himalaya (from Himachal Pradesh to Sikkim), ( Moore 1865, Dubatolov 2010, Singh et al. 2021), Mizoram (present study). Global records: Pakistan (Azad Kashmir), Tibet (western slopes of Himalaya in Zhangmu), China (Yunnan) ( Dubatolov 2010).

Remarks: The species is found to inhabit Himalayan chir pine forest in West Himalaya and East Himalayan subtropical wet hill forest and East Himalayan wet temperate forest in central and East Himalaya and North East within an altitude range of 712–2591 m.
