( Figs 93, 94 , 199, 200 )

TL: Sikhim [Sikkim, India]

= S [pilosoma] sordida Moore, 1865: 808 (TL: Darjeeling [West Bengal, India])

Material Examined: India , Arunachal Pradesh: [Dibang valley district], Mipi , 1 ♂, 31.x.2017, N. Singh leg. ( NZCZSI; 12547/H10); [West Kameng district], Bomdila, 4 ♂, 25.vi.2018, H. Singh leg. ( NZCZSI; 12548/H10), Shergaon, 2 ♂, 26.vi.2018, H. Singh leg. ( NZCZSI; 12546/H10) .

Diagnosis: Forewing length: ♂ 17 mm. Lemyra (T.) sordidescens ( Figs. 93, 94 ) is externally similar to L. (T.) multivittata ( Figs. 65, 66 ), but differs by forewing suffused with a pale yellowish brown and abdomen crimson above (in L. (T.) multivittata , forewing is suffused with creamish white and abdomen is yellowish or orange yellow).

Distribution. Indian records: Sikkim, West Bengal (Darjeeling) ( Dubatolov 2010, Singh et al. 2021), Arunachal Pradesh (present study). Global records: Bhutan, Myanmar (Kambaiti), Thailand ( Rothschild 1910, Černý & Pinratana 2009, de Freina & Thomas 2015).

Remarks: Lemyra (T.) sordidescens is reported from Central Himalaya. The current records of this species expand its distribution to the East Himalayan landscape of Arunachal Pradesh from an altitude up to 2400 m. The species is encountered from East Himalayan wet temperate forest and East Himalayan mixed coniferous forest in Arunachal Pradesh.
