Additional material examined. THAILAND: 1 male , Chumphon Prov., 162m, Pa Toh, Ban Lang Tang , 9°46'5''N, 98°46'59''E, 3.V.2008, K. Černý leg., gen. slide No.: AV8368 ♂ ( CKC) ; 1 male, same data as previous but 2–3.XII.2007, gen. slide No.: AV8370 ♂ ( CKC) ; 1 male, 1 female, same data as previous but 7.XII.2005, gen. slide No.: AV8457 ♀ ( CKC) .

Notes. (1) Lithosia fumidisca was originally described from an unspecified number of female specimens originating from two localities (“Sikhim; Tenasserim Valley”) ( Hampson 1894). Subsequently, Hampson (1900) cited only one female from Tenasserim Valley as “type”, which, according to the Article 74.5 of ICZN (1999), should be considered as lectotype designation. (2) The species was placed in the genus Brunia by Dubatolov & Zolotuhin (2011).

Diagnosis. The forewing length is 10.0–11.5 mm in males and 11.0–12.0 mm in females. The male genitalia of D. fumidisca are similar to D. navneetsinghi but differ in the narrower arms of the tegumen, the longer valva, and the larger proximal diverticulum. As the female of D. navneetsinghi remains unknown (see below), the female genitalia of D. fumidisca were compared to the morphologically closest D. trimacula instead, from which D. fumidisca can be distinguished by the larger setose postvaginal lobes of the 8 th sternite, the presence of a sclerotised swollen fascia on the posterior margin of the 7 th sternite, and the broader posterior sclerotised section of the corpus bursae.

Distribution. The species is known from south-eastern Myanmar (Tanintharyi Region) ( Hampson 1894) and Southern Thailand (Chumphon Province) (present study).
