( Figs. 2 , 7 )

Rhagoba ovellata Du & Li, 2012: 370–371 , fig 2, 5. TL: Xizang (Tibet) Autonomous Region , China.

Diagnosis. R. obvellata Du & Li, 2012 is morphologically very similar to R. octomaculalis ( Moore, 1867) , but it can be distinguished by the following genital characteristics: the apex of the uncus is broader than that of R. octomaculalis , and the distal part of the sacculus is straight in the male genitalia ( Fig. 7 ); the antrum is narrow, and shorter than that of R. obvellata in the female genitalia ( Du & Li 2012, p. 370, Fig 5 ).

Material examined. (1 ♂): LAOS: 1 ♂, Phosabous National Protected Area, Ban Tha , Xieng Khouang Prov., 5 IV 2016 (Bae Y.S., Park B.S., Na S.M., Kim J.W., Lee D.J.), (19°45´07.35”N 103°33´25.34”E Alt. 1298 m), genitalia slide no. INU-6810L .

Distribution. Laos (new record), China.

Remarks. This species is recorded from Laos for the first time. According to Du & Li (2012), it exhibits two types of variation: the first type has a small reniform translucent patch on the forewing ( Fig. 2 ); the second type lacks a translucent patch on the forewing ( Du & Li 2012, p. 368, Fig. 2B ).
