Original description, Meyrick 1890
Tymbophora, n. g.
Head with appressed hairs; ocelli absent; tongue well-developed. Antennae moderate, in male filiform, minutely ciliated ( ¼ ), basal joint moderate, without pecten. Labial palpi very long, recurved, second joint with appressed scales, terminal joint almost as long as second, slender, acute. Maxillary palpi very short, appressed to tongue. Thorax with small posterior crest. 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 hindmargin, 11 from middle. Hindwings over 1, trapezoidal-ovate; towards inner margin and base of 1b clothed with long hairs, 1b shortly furcate at base, 3 and 4 short-stalked, 5 tolerably parallel, 6 and 7 from a point, 8 connected with cell at a point before middle.
This is a simple development of Telecrates, differing from it essentially only by the crested thorax.

Original description, Meyrick 1890
Tymb. peltastis, n. sp.
Both sexes 19-27 mm. Head ochreous-whitish. Palpi whitish, second joint ochreous-brownish, except at apex and towards base beneath. Antennae whitish fuscous. Thorax very pale whitish-ochreous, more or less fuscous-tinged posteriorly, crest pale reddish-fuscous in front. Abdomen fuscous-whitish, segments with obscure narrow median transverse reddish bars. Legs ochreous-fuscous, femora white, posterior tibiae whitish-ochreous. Forewings elongate, moderate, costa moderately arched, apex obtuse, hindmargin sinuate, hardly oblique; very pale whitish-ochreous, with fine scattered black or brownish scales, more or less tinged or suffused with pale fuscous except towards anterior half of costa, sometimes very faintly; a trapezoidal deep brown-red blotch, irrorated with black and a few ochreous-whitish scales, extending on inner margin from 1/3 to ¾, narrowed upwards, upper side flat, not reaching half across wing; three or four brownish dots on posterior half of costa: cilia whitish-ochreous, on costa barred with brown-red, on hindmargin with terminal half barred with brown-reddish, at anal angle with a brown-red basal spot irrorated with black. Hindwings fuscous-grey, more or less suffused with pale whitish-ochreous anteriorly; cilia ochreous whitish, with two cloudy pale fuscous lines.
Brisbane, Queensland; Sydney and Cooma (3,000 feet), New South Wales; Adelaide, South Australia; Fremantle, West Australia; in December and January, not uncommon. Larva 16-1egged, stout, cylindrical, with scattered pale hairs; pale greyish-ochreous; spots moderate, dark fuscous; subdorsal strong, fuscous; sides irregularly marked with light pinkish; head irregularly spotted with dark ochreous-brown; second segment grey-whitish, with a suffused ochreous-brown transverse median band spotted with dark fuscous; anal segment speckled with black: feeds on Angophora lanceolata, residing in a chamber of silk beneath the bark, in October.

Male genitalia
Uncus: dorsally deeply divided into two lobes, fusing apically into a downturned point (‘beak’); strongly sclerotised at apex; setose laterally on exterior of uncal lobes; paired patches of setae on underside of beak; laterally on uncal lobes; with setae; sparse scobinations on beak; gnathos: two arms fused at base to uncus, produced anteriorly to form a slightly upturned, curved, pointed beak; strongly sclerotised at apex; some lateral setae at base; very finely scobinate on upper surface of end of beak; tegumen: broad, gently arched, smooth; articulation with vinculum slightly sclerotised; vinculum narrow sclerotised margins, pointed at base; saccus small; transitilla absent; juxta long lobed, v-shaped; valva: long, upturned, curved; thinly sclerotised sinus in 1st ¼ beneath costa, beside clasper. Finely and densely setose; longer at proximal end, shorter towards apex. Sinus smooth; valva, costal process: bifurcation at costal base, lower division setose; valva: costa: concave at base, very slightly sinuate, one convexity. Apex turned slightly inward, rounded; first ¼  of costa thickened; post-saccular margin: gently curved, apex rounded, finely setose; sacculus: nearly straight, curved only at apex and base; setae on proximal end of upper margin, and on apical area; lower saccular margin: nearly straight, curved only at apex and base; apex tenuous, tapering, pointed, indefinite. claspers: on a short stalk from the upper saccular margin, tapering outwards to about ½; upper ½ straight-sided; apex truncate. Apical spine from inner margin, hooked; defined boundary at base of clasper; apical spine sclerotised, outer margin smooth; inner margin densely and finely setose. Apex with longer tuft of setae; densely scobinate beneath setose areas, extending into sinus of valva; anellus: a rounded bulb to just above the height of the juxta; from there, two elongate lobes with 6 spines on their outer margin;. aedeagus narrow, broader in 1st 1/3.
Food plants: Larva webbing green leaves with silk and beneath bark. Larval foodplants: Eucalyptus polyanthemos, Angophora costata (Myrtaceae). (Edwards, 2003).
Flight period: December, January.
Distribution: Australian Capital Territory, New South Wales, Queensland, South Australia, Tasmania, Victoria, Western Australia. Endemic. (Edwards, 2003).
