Parastega niveisignella is a moth in the family Gelechiidae. It was described by Philipp Christoph Zeller in 1877. It is found in Panama, Colombia and Peru.[1]
The wingspan is 12–14 mm. The forewings are blackish brown with a purple sheen. A narrow white streak runs from the basal fifth of the costa obliquely outwards and downwards to the fold and is continued much attenuated and obscurely beyond the fold outwardly in a shallow curve. There is an interrupted, light brown, longitudinal streak on the fold and a small white costal spot at the apical fifth. The hindwings are dark fuscous.[2]
