Distribution and ecology. – Lepidocupania guillauminii is endemic to Chuuk atoll in the Caroline Islands, where it grows in lowland evergreen forests on volcanic soil and humus (ADEMA, 1991).

Note. – While ADEMA (1991: 122) noted that the available material of this species is rather incomplete and that it resembles both L. concolor and L. samoensis, he recognized it as distinct based on several differences in the amount of indument and in features of the fruits.
