Original description, Meyrick 1890
Plectophila n.g.
Head loosely haired; ocelli absent; tongue developed. Antennae moderate, in male serrate, shortly ciliated ( ¼ - ½ ) basal joint moderate, without pecten. Labial palpi long, recurved, second joint with appressed scales, slightly roughened beneath, terminal joint shorter than second, with appressed scales, acute. Maxillary palpi very short. Thorax smooth. Abdomen moderate. Posterior tibiae rough-haired above and beneath. Forewings with vein 1 furcate towards base, 2 from 2/3,  3 from angle, 7 and 8 stalked, 7 to apex, 11 from middle. Hindwings 1, oblong- ovate; base below median and inner margin clothed with long hairs, 1b shortly furcate at base, 3 and 4 from a point, 5 tolerably parallel, 6 and 7 from a point, 8 connected with cell at a point towards base.
Forewings with an ochreous-brown fascia near base.                 50. electella.
[Forewings] without [an ochreous-brown fascia near base.]      51. discalis.

Xylorycta Meyr.
I propose to widen the definition of the genus Xylorycta, so far as to unite with it the genera Lichenaula, Telecrates, Clerarcha, Plectophila, and Chalarotona. These were all published by me at the same time, and I select the name of Xylorycta for the resulting group because I made that typical of the family and therefore gave it precedence. The structural characters are thus extended in the following particulars: Antennal ciliations of ♂ variable (½ -3); 7 of forewings to apex or termen; 6 and 7 of hindwings approximated, connate, or stalked. (Meyrick 1905).

[Perixestis] Type eucephala Turn. I note here that the genera Plectophila Meyr. (type electella Walk.) and Telecrates Meyr. (type laetiorella Walk.) are good and tenable genera, not to be merged in Xylorycta. Meyrick 1917).

[Araeostoma] Distinguished from Plectophila by the nearly obsolete tongue, short palpi, and peculiar male antennae. In general facies the following species [Araeostoma aenicta] nearly resembles Plectophila poliochyta Turn. [Clerarcha poliochyta]. (Turner, 1917).

Gen. plectophila.
To this genus I refer Lichenaula choriodes Meyr., poliochyta Turn. [Clerarcha poliochyta], and micradelpha Turn. (Turner, 1917).

He [Meyrick] also establishes the genus Iulactis with a new type species semifusca (which I possess) as the type, to also include insignis Meyr. But in my opinion these last two species are Xyloryctinae, and should be referred to the genus Plectophila Meyr. or at least very near it. Vein 2 of the forewings in them arises from 2/3 or ¾. (Turner, 1919).
