Original description, Walker 1864
Mas et foem. Corpus crassum. Proboscis brevis. Palpi subarcucati, oblique ascendentes, capitis latitudine non longiores; abdomen alas posticas paullo superans. Pedes robusti; tibiae posteriores fimbriatale. Alae anticae, apice subrotundatae, costa basi subconvexa, margine exteriore subobliquo.
Male and female. Body very thick. Proboscis short. Palpi smooth, slightly curved, obliquely ascending, not longer than the breadth of the head; third joint lanceolate, half the length of the second. Antennae smooth, much shorter than the fore wings. Abdomen extending a little beyond the hind wings Legs stout, rather short; posterior tibiae fringed; spurs stout, moderately long. Wings long broad, smooth. Fore wings slightly rounded at the tips; costa slightly convex towards the base; exterior border slightly convex and oblique; veins much like those of Cryptophasa.
Subsequent description, Meyrick 1890
Maroga, Walk.
Head with appressed scales; ocelli absent; tongue short. Antennae moderate, in male flatly dentate or filiform, shortly ciliated (½), basal joint somewhat swollen, without pecten. Labial palpi moderately long, curved, ascending, second joint with appressed scales, slightly rough beneath, terminal joint about half second, smooth, acute. Maxillary palpi very short. Thorax smooth. Abdomen stout, sides clothed with projecting hairs. Anterior tarsi and tibiae more or less thickened with scales, middle tibiae rough-haired above, posterior tibiae densely rough-haired above and beneath. Forewings with vein 1 long-furcate towards base, 2 from 3/5, 3 from angle, 4 and 5 closely approximated at base, 7 and 8 stalked, 7 to apex or costa, 11 from middle. Hindwings over 1, oblong-ovate, towards base below median and towards inner margin densely clothed with long hairs, 1b shortly furcate towards base, 3 and 4 from a point or short-stalked, 5 tolerably parallel, 6 and 7 from a point or short-stalked, 8 connected with cell at a point towards base.

[Echiomima] Type mythica Meyr. I formerly included this in Maroga, but it is now evident that it is a good genus of peculiar (probably snakelike) facies, distinguished by costal termination of vein 7 of forewings (in Maroga apical); from Eschatura, which is also nearly allied, it differs by the short terminal joint of palpi. (Meyrick, 1898).

[H. Edw., Ins. Life III. 386 (1891), wrongly quotes this genus as ‘Morgia.’] (Walsingham and Durrant, 1900).
The timber or wood boring moths are well represented in Australian forests, and many of the smaller forest and scrub trees are killed by their larvae. The moths deposit their eggs upon perfectly sound, healthy trees. Some, like the Cryptophaginae, of which the cherry-tree borer is an example, simply make a hole in the stem and a short, vertical burrow below, webbing the bark in front, and coming out at night to feed. Thus they gradually eat off all the bark surrounding the bore before they pupate, and thus kill large branches. Others, like the wattle-borers, feed down the centre of the stems, and are true timber feeders, ready when full-fed to pupate at the end of the burrow, which comes so close to the outer bark near the pupal cell that on emergence the moth can push her way quite easily through the outer bark. (Froggatt, 1923).
The finest species belong to Cryptophasa, Xylorycta, Maroga and Uzucha. The depredations of the large genus Cryptophasa are very noticeable in the bush; ... (Tillyard, 1926).
Good examples, of progressive reduction in the maxillary palpi are exhibited in this large family. Lichenaula has a five-segmented palp; the genera Telecrates, Odites, Procometis, Agriophora [sic], Chalarotona, Scieropepla, Eschatura, Uzucha, and Catoryctis have each lost a segment; Xylorycta and Maroga have only three remaining; Cryptophaga rubescens has two, with a third represented by a minute papilla, while in C. nubila this papilla has been lost.
