3.1. Etymologie (Namenserklärung)
Davis (1986: 119) erläutert: "The species name is derived from the Latin inarmiger (unarmed), in reference to the relatively simple male genitalia."
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 Plesiophatus ist dabei bisher nur durch P. inarmigerus vertreten. Im Abstract (S. ii) erklärt er: "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. 116 ist zur Gattung und ihrer einzigen Art erfahren: "Although similar to Metaphatus, this genus appears somewhat intermediate between the former and Palaephatus. With most Metaphatus it shares a bifid apex on the maxillary palpi; a very similar, acute uncus, simple valvae, and rudimentary, hirsute gnathos in the male; and a very similarly developed colliculum in the female. It resembles Palaephatus in having lost all evidence of a sclerotized anellus and in possessing a more attenuated ovipositor with relative straight, posterior apophyses. This particular suite of characters, together with the unusually shortened corpus bursae, transverse sensory ridge, and simple, unspined eighth sternite of the female, easily distinguishes Plesiophatus from all other Palaephatidae."
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. inarmigerus war bei Davis (1986: 119) zu lesen: "This species is known only from the type-locality in the Andean lake region of Argentina and a somewhat disjunct site near the Chilean coast. The climate around Lago Puelo is unusually mild because of its low elevation. The Chilean locality consists of a relatively cool, moist Nothofagus forest situated in the mountains west of Temuco. Most of this area is in the process of being clear cut and replanted with exotic pine."
