3.1. Etymologie (Namenserklärung)
Davis (1986: 154) erläutert: "The specific epithet is derived from the latin pallidus (ashen, wan), in reference to the pale ground color of the wings."
3.2. Taxonomie
Butler (1883: 182) hatte mit falsus eine neue Art zu beschreiben. Da das Tier in keine bestehende Gattung passen wollte, schuf er dafür die Gattung Palaephatus, die dann von Davis (1986) zur Typus-Gattung seiner neuen Familie Palaephatidae (und Überfamilie Palaephatoidea) erklärt wurde. Er selbst beschrieb in dieser Arbeit gleich 25 neue Arten in 5 Gattungen aus Südamerika. Die Gattung Palaephatus wurde von ihm in 2 Untergattungen - Prophatus (mit den Arten Palaephatus dimorphus, P. leucacrotus, P. nielseni, P. spinosus, P. fusciterminus, P. albiterminus, P. striatus und P. amplisaccus) und Palaephatus (mit der nominotypischen Art P. falsus, P. pallidus, P. luteolus und P. albicerus) - aufgeteilt.
Im Abstract (S. ii) erklärt Davis (1986): "The sister group of the Palaephatidae (Palaephatoidea) has been determined as the Nepticuloidea + Tischerioidea largely on the basis of their similar monotrysian, non-piercing ovipositors, with the oviporous opening between the eighth and ninth abdominal sterna." S. 120 ist zur Gattung Palaephatus zu erfahren: "Including some 13 species, and at least one other species in too poor condition to name, this genus is the most successful group in the family. Some of its members also comprise the largest and most conspicuous species of Palaephatidae, with wing spans of up to 32 mm. Most Palaephatus can be recognized by the somewhat falcate outer margin of the forewing. This feature, however, tends to be less produced in a few of the smaller species. Along with its sister group, Apophatus, new genus, the male genitalia are characterized by a strongly curved pollex on the costal margin of the valvae."
Zur Art heißt es weiter (S. 154-155): "Palaephatus pallidus is closely allied to the type of the genus, P. falsus, and rubbed specimens, particularly of females, may be difficult to distinguish without dissection. The two species agree in having lost the antennal pecten and labial hair brush and in the possession of specialized hair pencil pockets in the male hind wing and very similar male genitalia. Palaephatus pallidus may be distinguished from its sister species by its paler, almost white ground color and by the presence of a short white longitudinal bar at the lower margin of the discal cell in the forewings. The male genitalia of this species differs from that of P. falsus by the different form of the gnathos, aedoeagus, and valvae shown in Figures 536-539."
3.3. Faunistik
Davis (1986) beschrieb 25 neue Arten der Familie. Sie stammen alle aus (meist höheren Lagen von) Chile und dem angrenzenden Bereich von Argentinien. Zu P. pallidus war bei Davis (1986: 154) zu lesen: "Although relatively uncommon, this species is widely distributed through the southern temperature forest (Valdivian) of Chile, with only a single record known from the adjacent Andean frontier of Argentina. In Chile it has been found from the coastal Nahuelbuta Mountains south to Puyehue National Park and Chiloe Island."
