This species was treated in FRPS (31: 364. 1982) as Neolitsea acutotrinervia. However, the original description and type material of Tetradenia acutotrinervia show its characters to be quite similar to those of N. aciculata, from Japan, and so the two entities are here treated as conspecific.This species was treated in FRPS (31: 364. 1982) as Neolitsea acutotrinervia.
