Habit:

Description of adults: Examined: original description (Ponomarenko & Beljaev 2000). Forewing lenght: 4.5 mm, unknown. "Head with black hair-like modified scales. Antenna about 3/4 of forewing length. Thorax and tegula black. Forewing golden-yellow with two reddish-violet transverse fasciae at 1/6 and 1/3 of wing length, two costal spots at 1/2 and at 2/3 and a dorsal spot just beyond the half length of wing. Fringe grey. Hindwing dark-grey, darker distally, with violet shine: fringe grey."

Distribution:

So far, the species is known only around the type locality in the south of the Russian Far East (Ponomarenko & Beljaev 2000).

Biology:

The species has been found during daytime on meadows on 3-5 year old clearings in the mountain coniferous forest (taiga) with Abies nephrolepis, Picea ajanensis and Betula costata (Ponomarenko & Beljaev 2000).

Stages in development:

The early stages are unknown.

Anatomy:

genitalia. Uncus moderately short, broad, tapering posteriorly; a pair of rounded lobes between uncus and accessory claspers, with long hair-like setae at distal end; accessory claspers paddle-like, with a group of upwardly directed, short and stout spoinoid setae at distal end and a row of moderately long thickened setae at lower margin of inner surface; valves moderately long, broad, constricted medially, distal half bent upwards and very large and broad; at inner surface 2-3 rows of stout spinoid setae.

Diagnosis:

Within its distribution range, there are no other externally similar species. In the male genitalia, M. sikhotealinensis closely resembles Micropterix aureatella shikotanica Kozlov, 1988, but can readily be separated externally by the forewings markings and the black scales on the head. Furthermore, the uncus is broader basally and somewhat longer, the accessory claspers and additional lobes between them and the uncus also being slightly different.
