3.1. Etymologie (Namenserklärung)
Davis (1986: 141) erläutert: "The specific name is derived from the Latin albus (white) plus terminus (end, limit), in reference to the narrow white band on the termen."
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. 141): "Palaephatus albiterminus is closely allied to P. fusciterminus, as indicated by their similar color patterns and, more important, by the identical presence of two specialized androconial areas in the hind wing of the male, with their accompanying venational modification. Both species possess a slender longitudinal fold along the base of the medial vein, which contains an elongate hair pencil. Also present in both species is an oval pocket in the anal lobe. This opens ventrally, exposing two distinct types of sex scales, one attached to the inner dorsal walls (i.e., floor) of the pocket and the other type to the inner ventral wall. The two species may be easily distinguished by the different color of the forewing termen and fringe; that of P. albiterminus being mostly white and that of P. fusciterminus fuscous. The two species are further distinguished by their radically different genitalia, as illustrated."
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. albiterminus war bei Davis (1986: 141) zu lesen: "This common species is apparently restricted to the wetter areas of the temperate, Valdivian forests of southern Chile and Argentina. Records to date indicate that it is less abundant in Argentina. It is known to occur in the coastal ranges from Nuble Province (-36 °S) south to Chiloe Island (43 °S) and in the Andes from Cautin Province (~39°20'S) south to Puyehue National Park in Osorno."
3.4. Typenmaterial
Davis (1986: 135) schrieb zum Holotypus: "HOLOTYPE. — ♂. d. Aguas Calientes to 3 km W, 450-500 m, Parque Nacional Puyehue, Osorno Province, Chile; 12-20 Dec 1981, UV light trap, D.R. Davis, type no. 101170 (USNM)." Dazu kommen etliche Paratypen aus Chile und wenige aus Argentinien.
