Hyodectis is a genus of moth in the family Gelechiidae.
[1] It contains only one species, Hyodectis crenoides, which is found in Australia, where it has been recorded from New South Wales and Victoria.
The forewings are rather light brown, sometimes golden-tinged and with a rather broad straight shining white streak above the middle from the base to the apex, suffusedly edged beneath with dark fuscous, especially posteriorly.
There is sometimes a white dot at three-fourths touching its lower edge and is also sometimes an undefined fine whitish almost terminal line.
