Original description, Newman 1856
Genus Boydia, Newman.
Caput mediocre rotundatum, fronte laevigato; antennae elongatae, setaceae nullo modo ciliatae: labipalpi mediocres, 3-articulati, articulo basali brevi scite cyathiformi; 2do elongato, crasso, apice truncato; 3tio apicali gracili, brevi, nudo, peracuto, paullulum recurvo: alae anticae elongatae marginibus parallelis, disco longitudinaliter profunde unisulcato; posticae amplae, insecti quiescentis ultra anticos protrusae, margine costali fimbria longissima venuste ornatis.
The very remarkable appearance of this insect, reposing with its hind wings protruding from beneath its fore wings, as in the familiar Gastropacha Quercifolia, and each furnished with a plume of delicate long hairs attached to its costal margin, at once distinguishes it from any other of the Tineadae with which I am acquainted: the labial palpi also differ from those of any described genus, and the deep sulcus on the fore wings is a character of interest. I have dedicated the genus to Mr. Thomas Boyd, one of our most zealous and active Microlepidopterists. The genus will in all probability be found to be most nearly allied to our Anchinia [Oecophoridae].

Synonymic description, Meyrick 1890
Hypertricha, n.g.
Head smooth; ocelli absent; tongue developed. Antennae moderate, in male filiform, simple, basal joint moderate, without pecten. Labial palpi moderately long, curved, ascending, second joint with rough scales beneath projecting towards apex, terminal joint very short, ¼ of second, acute. Maxillary palpi very short, appressed to tongue. Thorax smooth. Abdomen moderate. Posterior tibiae rough-haired above. Forewings with vein 1 furcate towards base, 2 from 2/3, 3 from angle, 7 absent (coincident with 8), 11 from middle. Hindwings 1 ¼, subtriangular, apex rounded, costa in male with extremely long hairs from basal half lying beneath forewings, 1b densely haired towards base, shortly furcate at base, 3 and 4 short-stalked, 5 parallel, 6 and 7 from a point, 8 connected with cell at a point towards base.

Original description, Newman 1856
Boydia criniferella, Newman.
Alis anticis nigricantibus, albido-inoratis, striga basali lata binisque median is parvis albidis; posticis nigricantibus pilis plurimis longissimis fuliginosis margine antico ortis. (Alarum dilat. .1 unc.)
Basal cup-shaped joint of labial palpi white, second joint white beneath nearly to the tip, which is tinged with brown, third or apical joint white at the base, black at the tip, head brown, eyes large and black; thorax and abdomen brown, the apex of the latter testaceous; fore wings brown, irrorated with white scales; on the basal disk is a vitta composed of white scales, which terminates rather before the middle of the wing; this is interrupted by a dark-brown or nearly black blotch in the very centre of the wing, and beyond this are two short, white, parallel vittae; hind wings testaceous brown, the costal margin tinged with ferruginous, the hairs constituting the plume attached to the costa are ferruginous at base, dusky brown at apex:. beneath, body and legs whitish; wings dusky brown.
Three specimens of the insect  are preserved: it is totally different from any species previously described.

Synonymic description, Meyrick 1890
Hyp. ephelota, n. sp.
Male 24 mm. Head and thorax light fuscous, mixed with ochreous-whitish. Palpi fuscous irrorated with white, lower half of second joint white. Antennae fuscous. Abdomen brownish-ochreous, basal half light grey with three incomplete dull reddish bands. Legs dark fuscous, apex of joints ochreous-whitish, posterior pair ochreous-whitish. Forewings elongate, costa strongly arched, apex round-pointed, hindmargin extremely obliquely rounded; fuscous, irregularly strewn with ashy-whitish scales; an ill-defined dot of dark fuscous scales on submedian fold at ¼, a second in middle of disc, a third on fold beneath second, a fourth in disc at ¾, and traces of a fifth on fold towards anal angle; second and fourth connected by an ashy-whitish streak, and a less marked similar streak connecting the other three; some dark fuscous scales on veins posteriorly: cilia fuscous mixed with whitish. Hindwings fuscous; costal hairs bright ochreous towards base; cilia pale fuscous, with a darker basal line.
Mount Lofty, South Australia; one specimen.

Original description, Lower 1905
Hypertricha stenadelpha, n. sp.
Female, 20 mm. Head, palpi, and thorax cinerous grey-whitish, second joint of palpi fuscous at apex, terminal joint nearly half of second, acute. Antennae fuscous, obscurely annulated with white. Abdomen dull silvery-grey, segmental margins dull reddish. Legs cinerous-grey-whitish, anterior coxae whitish, posterior legs greyish. Forewings elongate, moderate, costa gently arched, termen strongly oblique; 7 and 8 coincident; cinerous-grey-whitish; a streak of white along fold from base to end of cell, containing an oblique fuscous patch in middle, and two or three fuscous dots on upper half at and near extremity; cilia cinerous-grey-whitish, terminal half grey-whitish; hindwings pale grey-whitish, somewhat fuscous tinged around apex; cilia grey, with a fuscous basal line.
Bears a striking resemblance to Procometis tetraspora Low., but the resemblance is superficial only; the neuration of the forewings is a specific distinction. Although the terminal joint of palpi is somewhat longer than the characters of Hypertricha, that is, one-quarter of second, I scarcely consider it necessary to erect a new genus for its reception, but should the male show additional characters there may be some justification for doing so.
Broken Hill, New South Wales. One specimen; in March.
