Lecithocera terrena is a moth in the family Lecithoceridae. It was described by Alfred Jefferis Turner in 1919. It is found in Australia, where it has been recorded from Queensland.[1]
The wingspan is 15–17 mm. The forewings are ochreous-grey-whitish, with the first discal dot at one-third, dark fuscous and distinct. The plical is obsolete and the second, nearly obsolete, discal is found before two-third. There is some fuscous irroration between it and the tornus and some fuscous irroration on the termen. The hindwings are grey-whitish.[2]
