Thiotricha glenias is a moth of the family Gelechiidae. It was described by Edward Meyrick in 1908. It is found in Sri Lanka.[1]
The wingspan is 8–10 mm. The forewings are silvery white, more or less tinged with ochreous and with the apical two-fifths orange ochreous anteriorly suffused. There is a grey mark from the dorsum before the tornus, angulated inwards near the dorsum, then outwardly oblique, reaching more than halfway across the wing, a round black dot at the apex, and another on the termen, each preceded by a whitish dot. The hindwings are whitish grey, thinly scaled, the apex tinged with orange and with a blackish apical dot.[2]
