Holotype. INDONESIA: East Nusa Tenggara, Flores Island, Borong , 8º49'05"S, 120º37'33"E, alt. 100 m, dry monsoon forest and banana plantations, 24–27.i.2020, ♂, V. Spitsyn & E. Spitsyna leg. [ RMBH Sph 0875].

Diagnosis. This species can be distinguished from all other congeners by having a specific shape of the male genitalia structure. It remotely resembles that of Stictane pectinata Holloway, 2001 but has a narrower valva and a longer saccular process (as long as the valva).

Description. Male morphology: Wingspan 9 mm, forewing length 4 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 gray; antemedial line dark grey; marginal area darkened. Upperside of the hindwing and underside of both wings gray. Male genitalia: Uncus long; tegumen v-shaped; saccus u-shaped. Valva long, acute apically, distal saccular process elongated and thin. Aedeagus broad; vesica with one large, narrow, sickle-like, curved spike. Female: Unknown.

Etymology. The species’ name means “small bear” in Latin, reflecting its small size and uniform “grizzly” coloration.

Distribution. This species is not known beyond its type locality (Borong) in West Flores.
