Note: Prionitis filiformis is a substitute name for P. angusta (Harvey) Setchell, published July 1899, a later homonym of P. angusta (Okamura) Okamura (1899: 4), published 20 January 1899. The latter name was intended to be a new combination of Gymnogongrus ligulatus Harvey var. angustus Harvey (1860a: 332; intended type locality: Shimoda, Japan), but this varietal name is invalid because the specific name was invalid at that time (see Art. 43.1). Gymnogongrus ligulatus was proposed as a new species by Harvey in his Ceylon exsiccata (1857a: no. 50), but no description was provided. The name was validated by Kützing (1869: 23–24, pl. 63: figs. a, b). Harvey's varietal epithet was validated by Okamura as Cryptonemia angusta Okamura (1895: 478, pl. IX: figs. 8–15). Thus, the authorship of the Japanese Prionitis angusta is (Okamura) Okamura, not (Harvey) Okamura as usually cited.
