Thiotricha synodonta

Thiotricha synodonta is a moth of the family Gelechiidae. It was described by Meyrick in 1936. It is found in Korea and Japan.[1]

The wingspan is about 16 mm. The forewings are white with a dark fuscous costal streak throughout, becoming ochreous-brown towards the apex, within it a very fine short very oblique white strigula beyond the middle produced along the costal edge to rather near the base, and another less oblique at three-fourths reaching half across the wing. There is an oblique-triangular dark fuscous blotch occupying the basal third of the dorsum, its apex reaching half across the wing before the middle, connected on the dorsum with another oblique-triangular blotch beyond the middle, of which the apex is produced as a slender discal streak to meet the apical ochreous-brown area, from the second blotch another dark fuscous line below this proceeds obliquely to the dorsum. The apical and terminal area are ochreous-brown, with a fuscous angular projection between these two lines, and enclosing a small black apical spot receiving a short silvery-leaden discal streak, three small white spots separated by blackish preceding this on the costa, and an erect white tornal mark. The hindwings are grey.[2]
