≡ Arytera lepidota Radlk. in Sitzungsber. Math.-Phys. CI. Konigl. Bayer. Akad. Wiss. Munich 9: 555. 1879.

Lectotypus (first step designated by TURNER, 1995: 182; second step designated here): NEW CALEDONIA. Prov. Sud: Mont Dore, s.d., Pancher [Mus. Néocal.] 222 ( P [ P00639113 ]!; isolecto-: C [ C10018554 ] image seen, K [ K000701492 ]!, MEL [ MEL1586135 ] image seen; NY [ NY00038710 ] image seen, P [ P05310135 ]!).

Distribution and ecology. – Lepidocupania lepidota is endemic to Grande Terre, where it is restricted to dense humid forest on ultramafic substrates, from 10 to 915 m. Most collections are from the main ultramafic massif of the south, although it is also recorded from a few isolated localities in the north, including Mont Do and Cap Bocage ( TURNER, 1995), and more recently from Kantalupaik (MUNZINGER et al., 2018).

Notes. – Seven syntype collections were cited in the protologue of Arytera lepidota: Balansa 1445, 2841 , Baudouin 134A, Pancher [Mus. Néocal.] 222, Vieillard 205, and 206. TURNER (1995: 182) designated Pancher [Mus. Neocal.] 222 as the lectotype. The original material deposited at P is, however, mounted on two sheets, necessitating the second step lectotypification designated here, for which we have selected the most complete and best-preserved sheet [ P00639113 ].
