Thiotricha tethela

Description

Thiotricha tethela is a moth of the Gelechiidae family. It was described by John David Bradley in 1961. It is found on Guadalcanal in the Solomon Islands. The wingspan is 9–10 mm. The forewings are white, in some examples with a weak very light fuscous suffusion. The markings are dark mouse grey and hair brown and the anterior edge of the costal margin is fuscous at the base. There is a dark mouse grey very outwardly-oblique wedge-like marking from the costa at about four-fifths, followed by and sometimes confluent with a small triangular spot and a small inwardly-oblique dash mixed with black and very near the apex. A broad hair brown or mouse grey suffusion is found along the inner margin from near the base to about three-fifths, followed by a slender wishbone-shaped marking, the upper-most fork of this being nearly straight and reaching to a little beyond the inner end of first costal marking, the lower fork curved and terminating at the blackish pre-apical dash from the costa. The hindwings are white, with a fuscous suffusion at the margins and a few dark fuscous scales at the apex.
