Original description, Lower 1894
Cryptophaga stenoleuca, n. sp.
Male, 40 mm. Head and thorax fuscous; abdomen whitish, with ferruginous segmental rings, second segment broadly orange-red; antennae and palpi yellowish-white; legs grey-whitish. Forewings moderately oblong, posterior slightly dilated. Costa straight, apex obtuse, hindmargin straight, with a slight sinuation beneath apex; fuscous, finely irrorated with black scales; a narrow whitish streak along costa from very near base almost to apex, attenuated at extremities; two very suffused and hardly traceable small dark-fuscous patches in centre of wing; two from near middle; cilia dark-fuscous, with a fine whitish line at base. Hindwings with hindmargin somewhat projecting at anal angle; snow-white, infuscated along hindmargin and apical half of wing; cilia snow-white, towards apex slightly infuscated.
One specimen, Duaringa, Queensland.
Nearest irrorata, Lew., but differs from that species by the white costal streak, besides being a more slender insect.
