Epermeniidae

Epermeniidae or the 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they have been divided in two subfamilies Epermeniinae and Ochromolopinae (e.g. Common, 1990: 321) but this is no longer maintained since the last group is probably hierarchically nested within the first (Dugdale et al., 1999).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 they share some features. 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).

==Identification== Epermeniidae are small narrow-winged moths, having a span of 7–20 mm, with conspicuous whorls of bristles on their legs, lacking spines on the abdomen unlike some similar moths. The smoothly scaled head bears no ocelli or "chaetosemata". They are most easily confused with Stathmopodinae (Oecophoridae), which unlike epermeniids have the tarsi of the forelegs and midlegs without the whorls of spines, and whose proboscis is scaled at the base. The projecting scale tufts on the inner margin of the hindwing is the easiest field character (Common, 1990).
