Description of adults: Examined: Original description by Heath (1986). "Forewing length: 2.9 - 3.3 mm; 3.3 mm. Wing expanse: 6.0 - 6.9 mm; 7.0 mm. Head pale golden yellow; antenna golden fuscous, basal segment pale golden. Thorax golden; tegulae bronzy purple. Forewing (Fig. 4) deep bronzy purple with scattered blue scales, a broad fascia at one-third, narrowing costally, a broad fascia at one-half, narrow or broken medially (sometimes asymmetrically in the same specimen) and a large, broad, curved costal spot at three-quarters, extending into cilia, golden; cilia bronzy golden, apically paler. Hindwing bronzy grey, purple-tinged; cilia bronzy grey, apically paler."

Distribution:

The species is only known from the type locality El Hadjar (formerly St. Joseph), 25 km south of Annaba, Algeria (Heath, 1986).

Biology:

Nothing is known about the biology of M. aureocapilla. The adults have been found on the wing at the end of march (Heath 1986).

Stages in development:

The early stages are unknown.

Detailed view
     

Genitalia. "Uncus short and club-shaped, completely fused with tegumen; accessory clasper long and slender with two small apical lobes, the inner one bearing two fairly long, very stout setae, the apical one bearing three similar, shorter setae and a row of very long, stout, pointed setae on opposite margin; an inner articulated, parallel-sided arm, bearing seven very long, stout, curved setae on apex. Clasper with apex and base greatly enlarged; apex with a long series of long, stout, pointed, marginal setae and a lobe with a group of long, stout setae on inner surface and a large group of long, stout, pointed basal setae arranged in a band on inner surface." (Heath 1986).

Genitalia. Unknown.

Diagnosis:

Externally, the species is not recognizeable with certainty. The male genitalia however, are very distinctive.

Phylogeny: The inflation of the valve base in the male genitalia suggest a relationship to some species around Micropterix klimeschi Heath, 1973, although there are some strinking differences too, like the inflated distal end of the valves or the additional parallel-sided arm inside the tegumen.
