Synonymic description, Walker 1864
MARISBA.
Mas. Corpus sat robustum. Proboscis brevis. Palpi recurvi; capitis latitudine multo longiores; articulus 2us subfimbriatus; 3us 2o paullo brevior. Antennae subserratae, subpubescentes. Abdomen lineare, alas posticas longe superans, lateribus subfasciculatis; Pedes postici sat validi, femoribus breviusculis, tibiis fimbriatis, tarsis squamosis. Alae anticae falcatae, margine exteriore subconvexo perobliquo.
Allied to Oecophora.      Male.— Body rather stout. Proboscis short. Palpi recurved over the vertex, much, longer than the breadth, of the head; second joint with a short thick fringe in front; third setiform, a little shorter than the second. Antennae minutely serrated and pubescent, more than half the length of the fore wings. Legs rather stout; hind femora short; hind tibiae fringed; hind tarsi squamous. Wings long, moderately broad. Fore wings falcate; exterior border slightly convex, very oblique.

Original description, Mayrick 1890
Pilostibes, n. g.
Head with appressed hairs; ocelli absent; tongue short. Antennae moderate, in male shortly bipectinated throughout, basal joint moderate, rather swollen, without pecten. Abdomen linear, extending much beyond the hind wings, with small  tufts along each side and with two apical lateral valves. Labial palpi long curved, ascending, second joint thickened with dense scales, more or less rough or almost tufted towards apex beneath, terminal joint shorter than second, with appressed scales, acute. Maxillary palpi very short, appressed to tongue. Thorax smooth. Abdomen moderate. Interior [sic] tibiae and tarsi thickened with dense scales; posterior tibiae rough-haired above and beneath.Forewings with vein 1 long-furcate towards base, 2 from 3/5, 3 from angle, 7 absent (coincident with 8), 8 to costa, 11 from middle. Hindwings 1 ¼, oblong-ovate; base below median, and inner margin clothed with long hairs, 1b shortly furcate at base, 3 and 4 from a point or stalked, 5 parallel to 4, 6 to 7 from a point or short-stalked, 8 connected with upper margin of cell at a point before middle. 
Certainly a development of Cryptophaga.

[Cryptophasa] The genus is distinguished from all but Pilostibes by the pectinated antennae of the male. (Meyrick, 1890).

[Eschatura] This genus belongs to the group formerly maintained as a distinct family under the name Xyloryctidae, and is intermediate between Uzucha and Pilostibes. (Meyrick, 1897).

The genus Pilostibes, Meyr., I have dropped, as in all the specimens I have examined veins 7 and 8 are stalked. I can only conjecture that Mr. Meyrick was misled by an abnormal specimen in which vein 7 happened to be absent. P. enchidias, Meyr., is included under the present genus; P. stigmatias, Meyr., under Xylorycta. (Turner, 1898).

PILOSTIBES, Meyr.
Forewings with veins 7 and 8 stalked or coincident, 7 to costa.
On reconsideration, I have determined to retain this genus, altering the definition as above, and regarding P. enchidias, Meyr., as the type; referring P. stigmatias, Meyr., to Xylorycta. (Turner, 1900).

[Xylomimetes] Type Pilostibes trachyptera Turn., (Trans. Roy. Soc. S. Aust., 1900, p. 6). A very distinct genus, most nearly allied to Pilostibes Meyr. (Turner, 1916).

Food plants: Larva boring in stem and tying cut leaves to bore entrance. Larval foodplants: Callistemon salignus, Melaleuca nodosa (Myrtaceae). (Edwards, 2003).
Flight period: October, November, December, January.
Distribution: New South Wales, Queensland. Endemic. (Edwards, 2003).

Remarks: The wing venation of the specimen I examined agrees with Meyrick’s description, ie veins 7 and 8 (R5 and R4) of the forewing are fused. In the hindwing, vein 8 is forked (Sc + R1 are divided towards the costal margin), which may be abnormal.
This venation places Pilostibes in a close relationship with Echiomima. The genitalia of these two genera also show many similarities.
Turner’s dilemma about Pilostibes may have resulted from confusion of members of this genus with superficially similar species of  Xylorycta.

The genus Pilostibes, Meyr., I have dropped, as in all the specimens I have examined veins 7 and 8 are stalked. I can only conjecture that Mr. Meyrick was misled by an abnormal specimen in which vein 7 happened to be absent. P. enchidias, Meyr., is included under the present genus [Cryptophasa]; P. stigmatias, Meyr., under Xylorycta. (Turner, 1898).

Five species have been referred to Pilostibes Meyrick, including P. stigmatias Meyr. (Fig. 23.12) which occurs mainly in rainforest from southern Queensland to Newcastle, New South Wales. The larvae have been recorded as stem-borers in Elaeocarpus obovatus (Elaeocarpaceae). (Common, 1990).

Flight period: September, December.
Distribution: New South Wales, Queensland. Endemic. (Edwards, 2003).

Remarks: Male antennae finely ciliate rather than pectinate or serrate. It is probably this feature that led Turner to include P. stigmatias in Xylorycta. However, the wing venation of P. stigmatias does not resemble the venation described in the generic description; neither do its distinctive male genitalia resemble those of P. basivitta. Barcoding also places these species at a considerable distance from each other. Perhaps Turner was right, and P. stigmatias belongs in Xylorycta.
