Description of adults: Examined: 1 . Forewing length: 9.0 mm. Head black; vestiture of hair-like scales on the head distant, light yellowish-grey, face with more adpressed scales; eyes semi-globular, black, about 0.45 mm in diameter; distance of eyes (frontally) about 0.55 mm; maxillary palpi well developed, long, with yellowish-grey, shining, distant scales; labial palpi short, about 0.45 mm long, diverging anteriorly; proboscis well developed, basally with rough, light yellowish-grey scaling, scales strongly shining; antennae about 2 1/2 () of forewing length, simple; basal segment inflated, whitish, flagellum weakly ringed light and dark from base to about 1/3 of its length, distally whitish shining; thorax brownish-grey, bronzy golden shining, tegulae brownish, shining too; forewings brownish-silvery-grey, in the distal part reticulated by dark veins and indistinct, fine, irregular and only slightly darker cross-lines; lighter scales within the grid fields enhance the impression of reticulation; a short, slightly darker, indistinct cross-bar at the discus; fringe like the ground colour, coppery to bronzy golden shining; hindwings with hair-like scales, not covering the wing membrane, scales only towards the apex somewhat broader; hindwings light greyish, with nacre-like to slightly violet shimmer; fringe light bronzy golden shining; underside of wings unicolorous brownish-grey with strong coppery to bronzy golden reflections; fringe like at the upperside; legs grey-brown, shining; foretibia with epiphysis; midtibia with a pair of spurs at the distal end; hindtibia inflated, with a long tuft of hair-like scales directed upwards and downwards, as well as a pair of spurs each at 0.7 of the tibial length and at the distal end; segments of fore- and midtarsi lightend at the end and therefore appearing to be ringed.

Distribution:

The species has been found so far with certainty only in the central Apennines (see also Karsholt & Nieukerken, 2004). The examined male has been caught in a height of 1500 m a.s.l. (Kurz & Kurz 2010).

Biology:

The day-active specimen has been on the wing in May at the edge of a forest of young beech (Kurz & Kurz 2010). No other data on biology are available.

Stages in development:

The early stages are unknown.

Diagnosis:

Nematopogon robertella (Clerck, 1759) is distinctly smaller, the dark bar at the discus is more prominent, the antennae are not ringed. Nematopogon adansoniella (de Villers, 1789) on the other hand, is distinctly more reticulated, the ground colour is more ochreous and less greyish and the antennae are distinctly ringed nearly to their tips (in N. prolai only in the basal third). The -genitalia of N. prolai are very similar to those of N. adansoniella.
