Forewings are rather dark fuscous, purplish-tinged, towards dorsum and costa more blackish numerous costal streaks, a spot in disc posteriorly, and two or three dorsal spots white; a black apical dot, strongly white edged anteriorly; cilia with three entire dark fuscous lines.

Taxonomy
The genus Paronix comes from para, meaning alongside and ornix named after the genus Ornix Treitschke, 1833, which refers to ornis, a bird. The genus Ornix originally included a wide range of feathery-winged microlepidoptera in the Coleophoridae and the Gracillariidae. Ornix was an early synonym of the genus Coleophora as a number of moths were name after birds. The feathery-winged moths were later restricted to Paronix. The specific name torquillella comes from torquis – a collar, ″from the prothoracic plate of the larva, which consists of four transversely placed black spots.[5]
