Holotype. INDONESIA: Flores Island , Bajawa, Manulalu Ecolodge, 8º51'45"S, 120º59'40"E, altitude 1100 m, eucalyptus plantation with patches of natural vegetation, 01–02.ii.2020, ♂, V. Spitsyn & E. Spitsyna leg. [ RMBH Sph 0878].

Diagnosis. Morphologically, the male genitalia of the novel species are somewhat similar to Stictane fuscus Bucsek, 2014 . However, the new species can be distinguished from S. fuscus by the following combination of characters: larger and stronger distal process of the valva (vs smaller and narrower); irregular valva apex (vs. rounded); and valva with its distal process and distal saccular process of the same length (vs distal saccular process protrudes much further than the apex of valva’ distal process).

Description. Male morphology: Wingspan 14 mm, forewing length 6 mm. Eye black. Antenna bipectinate, gray. Labial palpus very thin, gray. Head, thorax, patagium, tegula, legs, and abdomen gray. Upperside of the forewing: ground color light gray; three basal black spots; antemedial line broad, dark gray; two postdiscal black spots followed by a dashed postmedial black line; dashed black line along termen. Upperside of the hindwing and underside of both wings gray. Male genitalia: Uncus long; tegumen v-shaped; saccus u-shaped. Valva long, with straight distal process apically; distal saccular process very large. Aedeagus broad; vesica with one very large, leaf-like, slightly curved spike with rounded base, other leaf-like spike of moderate size, and a rhombus-shaped sclerotized area. Female: Unknown.

Etymology. The species’ name indicates that it bears an external resemblance to S. fuscus .

Distribution. This species is not known beyond its type locality (Bajawa) in Central Flores.
