Original description, Turner, 1917
COMPSOTORNA ECCRITA, n sp.
εδχχριτος, picked out.
♂ 32 mm. Head whitish; face pale fuscous. Palpi moderate, second joint reaching base of antennae, terminal joint stout, ½, fuscous, apex of second joint and a broad median band on terminal joint whitish. Antennae whitish, becoming fuscous towards apex; ciliations in ♂ 1. Thorax fuscous, anterior margin whitish.  Abdomen ochreous-whitish. Legs ochreous whitish. mixed with fuscous; anterior and middle tarsi fuscous; anterior tibiae densely dilated with hair-scales. Forewings moderate, costa gently arched, apex obtusely rounded, termen rounded, scarcely oblique; 7 and 8 coincident, running to apex; fuscous·; a large ill-defined basal subcostal whitish suffusion; a large ochreous-whitish tornal suffusion extending nearly to apex, and connected with basal suffusion above fold; some blackish scales tending to form a streak on basal half of fold; a large irregularly oval discal spot beyond middle, fuscous outlined with blackish; several fine short blackish streaks between this and apex; cilia pale fuscous towards apex mixed with whitish. Hindwings ochreous-whitish; cilia ochreous-whitish with a fuscous spot at apex.
Certainly allied to C. oligarchica, although vein 7 of forewings is absent - an unreliable character for generic distinction in this group. Xylomima Turn., is a genus near to and derived from Compsotorna.
N.Q. Kuranda near Cairns; one specimen received from Mr. F. P. Dodd.

Remarks: Turner’s confusing observations about the relationship of Compsotorna eccrita to the genus ‘Xylomima’ are apparently based on general appearance (facies) which, like wing venation, can be an unreliable taxonomic indicator in this subfamily.
C. xylomima, currently placed in Cryptophasa, is a species of Caenorycta. Xylomima is a nomen nudum.
The male genitalia of Compsotorna eccrita differ quite markedly from Caenorycta xylomima, particularly in the uncus and gnathos. There is, however, a similarity in that the apex of the sacculus terminates in an extended process, which is unusual. From this I am drawn to conclude that there is a possible relationship between Compsotorna and Caenorycta. A common ancestor is suggested rather than any directly lineal relationship.

Original description, Meyrick, 1890
Comps. oligarchica, n. sp.
Male 22mm. Head and thorax ochreous-whitish, sides of face ochreous. Palpi whitish, second joint externally fuscous. Antennae fuscous. Abdomen ochreous-whitish, posterior half of second segment dull red. Legs whitish, anterior pair whitish-ochreous. Forewings elongate, moderate, costa moderately arched, apex rounded, hindmargin not oblique, rounded beneath; whitish ochreous, with a few fine scattered black scales; a fuscous-grey straight longitudinal streak above middle from base to near apex, margined beneath first with blackish and then with an ochreous suffusion, and above and posteriorly by a white suffusion reaching almost to costa; a triangular reddish-brown spot in disc at 2/3, with a central transverse pale mark, its upper side rounded and whitish-margined, intersecting the fuscous longitudinal streak, its two lower sides black-margined;, cilia whitish-ochreous. Hindwings and cilia whitish-ochreous.
Toowoomba, Queensland; one specimen in December.
Synonymic description, T.P. Lucas, 1902
Theiosia aetheria, n. sp.
♀. 28 mm. Head and palpi reddish-ochreous; antennae fuscous, basal joint ochreous; thorax ochreous, with a rich chestnut band behind collar; abdomen whitish-ochreous; legs ochreous, tarsal joints of hind pair fuscous. Forewings with costa gently rounded, hindmargin rounded, reddish-ochreous, sparsely speckled with black dots, and marked with white, grey- black, and chestnut. Forewings with a kidney-shaped rich chestnut-coloured discal blotch, extending over middle third of wing, beyond ½ costa; this is bordered on costal edge by a fine white line; and this is again enclosed by a broad band of smoky black, which extends from base of wing to opposite 7/8 costa, and is again enfolded by a broad white suffusion, reaching to costa at base, and gradually receding from costa at ¼, leaving a band of ground colour for costal border to apex; the white is freely speckled with black dots; a subhindmarginal line of black dots, and a hindmarginal reddish-brown line: cilia reddish-ochreous, diffusing to reddish-fuscous at apex and apical hind margin. Hind wings light ochreous; cilia light ochreous.
