Noch unbekannt! Davis (1969: 139) schloss aus der Beschaffenheit des Ovipositors, dass die Arten der Gattung Acanthopteroctetes - wie die von Eriocrania - Blattminierer sein dürften.

3.1. Etymologie (Namenserklärung)

Davis (1984: 50) erklärte: "The uniformly light golden brown forewings of A. aurulenta easily distinguishes it from the other darker, banded-wing species in the family. This characteristic color pattern has suggested the specific name, derived from the Latin aurulentus (golden, ornamented with gold)."

3.2. Faunistik

Davis (1978: 96) hatte bei seiner Beschreibung von A. unifascia schon angedeutet, dass noch eine weitere Artbenennung erwartet werden kann: "A second unnamed species was collected 8 July 1966 by J. H. Baker from Spring Creek, Baker, Oregon. This locality is also the original source of the type series of A. bimaculata. Although the unique female specimen was badly broken in shipment to the Smithsonian Institution (where it is now deposited), most of its diagnostic features can easily be observed. The forewings of this species are distinct in being uniformly pale golden brown, and the head vestiture is stramineous in color. The female genitalia differs greatly from that of other known members of the genus in possessing a more broadly depressed and irregularly lobed vistibulum (Figure 332). The spermathecal papilla is indistinct and unsclerotized. The common oviduct apparently enters the vistibulum at a more typical (for this family) midventral position." Die Benennung der Art ließ auf sich warten, bis auch das Männchen gefunden worden war. Davis (1984: ) konnte dann melden: "Recent collecting in central Utah by Ronald W. Hodges resulted in the discovery of the male of an undescribed species of Acanthopteroctetes previously mentioned in the literature (Davis, 1978:96, 129) but not named. The availability of both sexes of this species now enables me to name this insect, which constitutes only the fourth species described for the family."

Davis (1984: 50) leitete aus seinen beiden Typusexemplaren ab: "Distribution. Northwestern Oregon and central Utah."
