Material examined. Holotype female RMBH Sph 0571, INDONESIA: Lesser Sunda Archipelago, East Nusa Tenggara Islands , Flores Island : Labuan Bajo , garden and native grassland on the sea coast, 8.5225°S, 119.8711°E, 24 January 2015, Bolotov leg.; Flores Island , Labuan Bajo , Mbeliling Mountain Ecolodge , mountain monsoon forest, 8.5892°S, 119.9867°E, 05–07 February 2020, V. Spitsyn & E. Spitsyna leg. – 1♂ ( RMBH Sph0828); Flores Island , Bajawa, Wolokoro Ecolodge, heavily disturbed monsoon forests and eucalyptus plantings, 8.8172°S, 120.9342°E, 08 February 2020, V. Spitsyn & E. Spitsyna leg. – 1♂, 1♀ ( RMBH Sph0829 and Sph0922).

Differential diagnosis. The male of E. wallacei ( Flores) could be distinguished from that of E. caesarea (Timor) by having 6 strong, conical cornuti at the apex of vesica (vs 39–62 cornuti in E. caesarea ).

Description of the male. Wingspan 33–41 mm, forewing length 20–23 mm (N = 2). Head light brown to dark brown. Labial palpus large, its length ca. 2.5 of eye diameter, bears dark brown or blackish scales with white distal ends. Antenna brown, short, bipectinate. Thorax and legs light brown to brown. Forewing light brown to brown, without clear marking pattern. Hindwing narrow, elongated, with prominent cubital area, light brown to dark brown, with a lighter anal area and a large, distinct dark yellow spot with black points and wavy lines in the R-M area. Abdomen yellowish brown. Male genitalia. The genital capsule largely resembles that in E. caesarea , i.e. tegumen broad with two strong caudal hooks; vinculum narrowed; valva with short and massive dorsal process, ventral process finely toothed on inner margin; juxta fork-shaped with narrow lobes. Aedeagus short, tube-like; vesica elongated, tapering proximally, its apical part rounded, bag-like, and bears 6 strong, conical cornuti.

DNA barcoding data. The GenBank acc. numbers of the reference COI sequences for E. wallacei are as follows: MK 419950 (holotype female); OK083723 (male); and OK083724 (male). All the sequences are identical (i.e., belong to one COI haplotype) .

Distribution. Indonesia: Flores Island.
