Description of adults: Examined: Drawing of holotype () by Kozlov (1989): Forewing lenght: 1.9 mm. Antennae nearly completely broken; pronotum narrow, mesonotum with distinct medial suture; mesoscutellum reaches 2/5 of the length of mesonotum; forewings oval, fragments of scaly covering present; Sc branched, Sc2 reaching the costal margin at about 1/2 of forewing length, all other veins unstalked; R5 distinctly preapical; venation of hindwings hidden by the body; hind tibia twice as long as the femora, densely covered with long bristles, with a pair of spurs each at about 3/5 of the tibial length and at the distal end.

Distribution:

The species is known only form the single specimen from the type locality in Mongolia.

Biology:

Nothing is known about the biology of A. minima.

Stages in development:

The early stages are unknown.

Anatomy:

genitalia. Apophyses virtually absent.

Diagnosis:

The species differs from Auliepterix mirabilis Kozlov, 1989 mainly in the size, the forewing length being almost the half of that species (1.9 compared to 3.4 mm).

Phylogeny: Since no apomorphy for the genus Auliepterix Kozlov, 1989 has been identified, the relationship between A. mirabilis and A. minima is speculative only, as is the assignment of both species to the Micropterigidae.

Worth knowing:

The age of the fossil has been estimated to be between 150.8 - 140.2 Ma.
