Original desription, Meyrick 1894
Comocritis, n.g.
Head with appressed scales, sidetufts loosely spreading, projecting- between antennae; ocelli. present;- tongue developed. Antennae 2/3, in ♂ shortly bipectinated, with .streak of rough scales on  back near base, basal joint large, with dense pecten. Labial palpi moderate, curved, ascending, second joint loosely-scaled, terminal joint less than half second, pointed. Maxillary palpi very short, filiform. Posterior tibiae clothed with rough scales. Forewings with vein 1 b furcate, 2 from near angle, 7 to costa, 11 from middle, with a subhyaline groove on lower surface beneath 12 towards base. Hindwings 1, elongate-ovate, .cilia ¼, veins 3 and 4 from a point, 5 and 6 somewhat approximated at base.
Allied to Oeta [= Atteva, Yponomeutidae], but not closely.

Immature stages:

Distribution: Queensland, Papua New Guinea. (Edwards, 2003).

Remarks: The late J. Kyrki of Finland had informed us that Comocritis should not be in the Yponomeutoidea but he did not know its correct family. (Pitkin and Jenkins, 2004).

Food plants: larvae of Indian species feed on lichens and the bark of trees. (Meyrick 1920).
Flight period:
Distribution: Queensland, from the Daintree, south of Cooktown (Edwards, pers. comm., 2009).
Imbil, South-east Queensland.

Remarks: Very close to C. olympia. The serrations on the phallus relate to similar structures in C. heliconia and C. thespias (Gates Clark, 1955).
There appears to be a well-formed transtilla in the dissected male genitalia. This feature is otherwise absent in the Xyloryctidae. The relative size of the genitalia and phallus is also most untypical of other Australian Xyloryctidae. Barcoding results have proved to be inconclusive, as there is not enough material for comparison; whether this genus belongs in the Xyloryctidae remains a mystery. Apparently not related to other Australian genera; may be introduced.
