Leuronoma zymotis is a moth of the Gelechiidae family. It was described by Meyrick in 1909. It is found in South Africa. The wingspan is about 15 mm. The forewings are fuscous irregularly mixed with ferruginous-brownish and sprinkled with dark fuscous and with a blackish mark beneath the base of the costa, and one on the fold towards the base, each followed by longitudinal white-ochreous suffusion, the latter streak extending to the second discal. There are suffused white-ochreous oblique costal and dorsal opposite marks about three-fourths, not meeting. The hindwings are grey.
