Type material. Holotype ( Figs 45 , 84 ): male, “ Sumatra | Prapat HW 3 | 26.–30.XI.1982 | Dr. Diehl leg.” / “Slide | AV8372 ♂ | A. Volynkin ” ( MWM / ZSM, ex CKC).

Paratype. INDONESIA: 1 female , W Sumatra, Mt. Talang , 0°57'S 100°24'E, 18.IX.1991, secondary forest, 1600m, Graul & Schintlmeister leg., gen. slide No.: AV8373 ♀ ( CKC) .

Diagnosis. The forewing length is 12.0 mm in the male holotype and 13.5 mm in the female paratype. Dubatoloviana diehli sp. n. is externally very similar to D. pahanga but has a somewhat narrower forewing. Additionally, compared to D. pahanga , the male of the new species has more distinct forewing markings, and the female has a straighter costal margin of the forewing with a narrower outer ochreous yellow area at the apex. The male genital capsule of D. diehli sp. n. differs clearly from D. pahanga in the longer and less downcurved tip of the uncus, the thicker “cucullus”, and the narrower unilobate distal saccular process, which is bifurcate in D. pahanga . The phallus of the new species is somewhat longer and distally broader than in D. pahanga . The vesica configurations of the two species are similar but in D. diehli sp. n., the main chamber is somewhat longer than in the congener and the distal diverticulum bears a cornutus, which is absent in D. pahanga . In the female genitalia, D. diehli sp. n. is distinguished from D. pahanga by the wider gelatinous antevaginal plate and the shorter posterior sclerotised section of the corpus bursae.

Distribution. Indonesia (Sumatra Island).

Etymology. The new species is dedicated to the memory of the late Dr. med. Eduard Wilhelm Diehl (1917–2003), famous researcher of Sumatran insects and collector of the holotype. The name is a noun in the genitive case.
