Epermeniidae or "fringe-tufted moths" is a family of insects in the lepidopteran order with about 14 genera.
 Previously they have been divided in two subfamilies Epermeniinae and Ochromolopinae (e.g. Common, 1990: 321) but this is no longer maintained since the last group is probably hierarchically nested within the first (Dugdale et al., 1999).
 They are presently placed in their own superfamily but have previously been placed among the Yponomeutoidea or Copromorphoidea with which some features are shared.
 Their systematic placement among the apoditrysian  group "Obtectomera" (having pupal segments I-IV immobile) is however uncertain.
 They show some morphological similarities to the "plume moths" (Alucitoidea and Pterophoroidea), for example the wing fringe has similar groups of scales (Dugdale et al., 1999).
 There are also some similarities to Schreckensteinioidea, for example spiny legs and at least in some species an open-network cocoon.
 The genus "Thambotricha" from New Zealand may be the sister group of all other extant members.
 The most important genera are "Epermenia", "Ochromolopis" and "Gnathifera".
 The group has been extensively revised and catalogued by Dr Reinhard Gaedike (e.g. Gaedike, 1977, 1979).
Tunnel 57 was a tunnel under the Berlin Wall that on the third and fourth October 1964 was the location of a mass escape by 57 East Berlin citizens.
 Student and future astronaut Reinhard Furrer was among the West German escape helpers who assisted the East Berliners in escaping.
 During the escape, East German border guards came upon the scene.
 A West German escape helper, Christian Zobel, opened fire, the bullet piercing the shoulder of young East German guard Egon Schultz, who was then fatally wounded by friendly fire from another guard.
 This friendly fire was kept secret by the GDR government.
 A memorial plaque on the site today commemorates both the successful escape, and Schultz's death as a victim of the Berlin Wall.
Prof. Dr. Reinhard Alfred Furrer (25 November 1940 – 9 September 1995) was a German physicist and astronaut.
Reynders or Reijnders is a Dutch patronymic surname common in the Limburg area.
 The form Reinders is more common in the Eastern Netherlands and the flanking regions of Germany.
