Original description, Lower 1901
Cryptophaga hyalinopa, n. sp.
Male, 30 mm. Head, palpi, thorax, and legs fleshy-ochreous, head somewhat pinkish tinged, tarsi ringed with blackish. Antennae blackish., pectinations: 2. Abdomen blackish, second segment orange-red. Forewings elongate, moderate, costa, nearly straight, termen obliquely rounded; fleshy-ochreous, darker on basal third; a, fine black dot in disc at one-third, a second at posterior extremity of cell, and a third obliquely below and before; two others on fold beyond middle; an obscure row of fine blackish dots along termen to anal angle, not reaching apex. Hindwings semi-hyaline, basal two-thirds black; cilia whitish becoming fuscous around anal angle. Underside of both wings with basal two-thirds densely black.
Nearest balteata, Walk., but very distinct by the curious semi-hyaline hindwings. I received this species from the late Mr. G. Barnard as sarcinota, Meyr., but having now received that species I find that there is a very great difference between the two.
Duaringa, Queensland; one specimen in October.
Subsequent description, Lower 1902
Cryptophaga hyalinopa, Lower.
(Trans. Roy. Soc., S.A., p. 82, 1901.)
Female, 66 mm. Head, thorax, palpi, antennae, legs, and abdomen as in male. Forewings as in male, but, color clear fleshy-ochreous throughout; markings as in male. Hindwings pale ochreous, with a tuft of blackish hairs on innermargin above anal angle; cilia, pale ochreous.
The sexes of this species are very dissimilar in the hindwings, the male having the terminal half hyaline and the basal half black.
Cooktown, Queensland; one specimen.
Subsequent description, Turner 1902
Cryptophasa hyalinopa, Low.
(Trans. Roy. Soc., S.A., 1901, p. 82.)
Male, 31-32 mm. Head and palpi whitish. Antennae blackish, pectinations 1. Thorax pale pinkish-white. Abdomen blackish; apices of segments whitish; second segment reddish-orange. Legs whitish, anterior pair pinkish, annulated with blackish. Forewings rather narrow, costa nearly straight, apex round-pointed, hindmargin very obliquely rounded; slaty-brown; with five black discal dots; first at one-third of disc and one-third from costa; second before two-thirds of disc and one-third from costa; third before and below second; fourth and fifth closely approximated, above and below fold, about midway from first and third; cilia pale fuscous, with a dark fuscous basal line. Hindwings 1 ½; hindmargin slightly rounded; blackish; apical two-fifths free from scales and transparent; the line of division sharp, somewhat dentate; cilia, white.
Female differs as follows: 65-70 mm. Antennae white, finely annulated with dark fuscous. Forewings broader, costa moderately arched, hindmargin less oblique; pinkish; cilia with a series of blackish basal dots. Hindwings white, with an inner-marginal hairy patch. Abdomen with apical segments whitish.
Townsville, Queensland, in October; bred abundantly from Eucalyptus sp. by Mr. F. P. Dodd.

In an attempt to trace relationships among the gelechioids I examined the larvae of four Australian Xyloryctinae in the BMNH: Cryptophasa hyalinopa Lower, C. balteata Meyrick, Echiomima mythica Meyrick and Perixestis eucephala (Turner). These species also have the adfrontal area not reaching the vertical angle of the head and the distance between setae P2 is  almost the same as that between setae PI. Therefore it seems that the combination of both  characters of the head, i.e., adfrontal area not reaching the vertical angle and the distance  between setae P2 about the same as between setae PI, is a good diagnostic feature for distinguishing the larvae of Stenominae and Xyloryctinae from those of other Gelechioidea.
