Thiotricha tetraphala

This species was first described by Edward Meyrick in 1885 and named Thistricha tetraphala.^[4][2] In 1886 Meyrick gave a fuller description and corrected the misspelling of the genus name to Thiotricha.^[5] The male holotype specimen, collected in Dunedin, is held at the Natural History Museum, London.^[2]

The wingspan is about 12mm. The forewings are light grey, somewhat irrorated with grey-whitish in the disc. There are three dark grey spots, the first basal, the second triangular, in the disc before the middle, the third larger, oblong, beyond middle and resting on the sub-median fold. The hindwings are grey.^[5]
