Original description, Meyrick 1918
IULACTIS, n. g.
Head with appressed scales, sidetufts loosely raised; ocelli small, posterior; tongue developed. Antennae 4/5, in ♂ shortly ciliated, basal joint moderate, without pecten. Labial palpi very long, recurved, second joint with rough projecting hairscales beneath diminishing anteriorly or not continued to apex, terminal joint somewhat shorter than second, slender, acute. Maxillary palpi very short, filiform, appressed to tongue. Posterior tibiae rough-haired above. Forewings with 1b furcate, 2 from 4/5, 3 from angle, 7 and 8 stalked, 7 to apex, 11 from middle. Hindwings 1, trapezoidal, apex tolerably pointed, termen sinuate, cilia 4/5; 3 and 4 connate or short-stalked, 5 hardly approximated, 6 and 7 stalked.
Type semifusca Meyr.; as stated above, insignis Meyr. (which I now possess from Brisbane) is also referable here.
Other references
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).

Original description, Meyrick 1904
D. insignis, n. sp.
♂♀. 11-12 mm. Head, palpi, antennae, and thorax white; antennae in ♂ ciliated. Abdomen light greyish-ochreous. Legs dark fuscous ringed with white, posterior pair white. Forewings broader than in the other species, termen sinuate, rather oblique; shining white; a triangular blackish-grey blotch on base of dorsum; a deep golden-ochreous fascia from middle of costa to ¾ of dorsum, acutely angulated in middle; three deep golden-ochreous marks on costa beyond this, connected beneath; a series of six longitudinal black lines before termen, two upper surrounded with ochreous suffusion : cilia whitish-ochreous, with two faint darker lines becoming dark fuscous above apex. Hindwings broader anteriorly, 6 and 7 stalked; grey, lighter towards base; cilia pale whitish-yellowish.
Brisbane, Queensland: Sydney, New South Wales; from October to December, three specimens.

Original description, Meyrick 1918
Iulactis semifusca, n. sp.
♂♀. 10-11 mm. Head, thorax shining white. Palpi white, anterior edge of terminal joint blackish. Abdomen pale greyish. Forewings elongate, rather narrow, costa slightly arched, apex tolerably pointed, termen sinuate, oblique; brown, on dorsal half or sometimes wholly suffused fuscous; a broad white supramedian streak from base to 2/3, not quite reaching costal edge on its basal half, thence narrowed to extremity; a very oblique slender white streak from costa beyond middle to extremity of a black subapical dash; two short white transverse marks from costa beyond this, and a white wedgeshaped spot along apical part of costa; a white suboval blotch almost on lower half of termen, marked with four or five fine black longitudinal lines: cilia white, a dark fuscous subbasal line lighter and thicker on termen, and fuscous apical shade. Hindwings light grey, somewhat darker posteriorly; cilia pale grey, round apex whitish.
Queensland, Herberton, Townsville, December (Dodd); three specimens.

Remarks: The specimens mistakenly labelled Iulactis semifusca in the ANIC collection are in fact Xylorycta ceratospila, a fact that Patrick Strutzenberger has recently confirmed by photographing the types at the BMNH. I am fairly certain that X. ceratospila probably does not belong in Xylorycta, but is another species of Iulactis. However, this speculation needs to be confirmed by barcoding results. There is a remote possibility that X. ceratospila and I. semifusca are identical.
Specimens labelled Plectophila sp. ANIC 17 of the BOLD website, following the ANIC collection order, are in fact Iulactis semifusca: http://www.boldsystems.org/views/taxbrowser.php?taxid=365435 .
The male genitalia of Plectophila sp. ANIC 15, a species close to Iulactis semifusca, resemble other species of Plectophila and it is likely that the genus Iulactis needs to be properly examined and revised, and its relationship to Plectophila clarified.
