Heteralcis palathodes is a moth in the Lecithoceridae family. It was described by Meyrick in 1906. It is found in Sri Lanka. The wingspan is 14–16 mm. The forewings are ochreous-yellow with small dark fuscous spots on the costa at and near the base, and near the base of the dorsum. There are three irregular obscure brownish-ochreous fasciae at one-fourth, the middle, and three-fourths, dilated in the disc, and a similar transverse line before the second, sometimes mostly confluent with it, the third sometimes suffused with fuscous. The hindwings are dark grey in males, with the apex whitish-ochreous, with a subdorsal groove enclosing a long ochreous-yellowish hair-pencil. The hindwings of the females are grey, with the apex and upper part of the termen suffused with whitish-ochreous.
