Thiotricha syncentritis is a moth of the Gelechiidae family. It was described by Meyrick in 1935. It is found in Indonesia (Java). The wingspan is about 15 mm. The forewings are grey-whitish with a faint tinge of flesh-colour and with a slender blackish longitudinal supramedian streak from the base to the apex, and another rising from the base of the dorsum, running subdorsal and gradually converging to meet the first at the apex. There is a very oblique blackish striga from the costa at four-fifths also meeting these at the apex. There is a suffused dark grey line along the fold throughout, and another along the dorsum and termen throughout. The hindwings are bluish-hyaline, minutely freckled grey and with the veins dark grey, the costa and termen narrowly suffused dark grey.
