Thiotricha acronipha is a moth of the family Gelechiidae. It was described by Alfred Jefferis Turner in 1919. It is found in Australia, where it has been recorded from Queensland.[1]
The wingspan is about 11 mm. The forewings are whitish, towards the apex slightly ochreous-tinged and with a short longitudinal fuscous streak ending in the termen below the middle. From its anterior end a similar streak runs parallel to the termen and there is a short oblique streak from the costa at five-sixths, as well as an elongate clear white apical dot edged above with black beneath with fuscous. The hindwings are pale-grey with a minute fuscous apical dot.[2]
