Licania arianeae can be recognized by the leaves with conspicuous stomatal crypts and long persistent stipules, easily observed characters even in sterile specimens of Chrysobalanaceae . These characters are shared with L. naviculistipula , but L. arianeae can be distinguished by the elliptic to oblong-elliptic leaves, 9–13 pairs of primary veins and 7 stamens ( vs. oblong-elliptic to ovate, 8–9 pairs, and 8 stamens in L. naviculistipula ). Collected with flowers in February and May.

Licania arianeae is here confirmed as endemic to the Atlantic Forest, with records from Rio de Janeiro and EspÍrito Santo ( Barros et al. 2022). In the latter, it occurs in Restinga, Ombrophilous forest and Mata de Tabuleiro , in Itapemirim and Linhares municipalities. The taxon is classified as

“Endangered” (EN) ( Fraga et al. 2019; Brasil 2022) and it was collected in only one protected area (Reserva Natural Vale).

The common name for this species is quebramachado ( D.A. Folli 228).
