SPECIMENS EXAMINED. — New Caledonia. North Province, Poindimié, Tango plateau, Hoeêne upper valley, 20°58’44”S, 165°5’53”E, on rock of small waterfall in a gallery forest, 347 m, 11.X.2019, Thouvenot NC3028 PC[(PC0712110)]; South Province, Païta, Mt Ouin, along the path to the summit, on dead wood in a wet forest in ultramafic massif, 1000-1025 m, 19.IX.2016, Thouvenot NC2097.

Lobatiriccardia coronopus (De Not. ex Steph.) Furuki subsp. coronopus was the single species of the genus hitherto reported from New Caledonia (Thouvenot et al. 2011). Lobatiriccardia alterniloba can be recognized from the later by the remotely toothed thallus margins, female branches with scale-like to fimbriate paraphyses without unicellular cilium, male branches with dorso-lateral wings 2-3 cells wide, not ciliate. The distribution of L. alterniloba, reported from New Zealand, Australia, Tasmania and Vanuatu (Preussing et al. 2010) is consistently expanded to New Caledonia, in both provinces of Grande Terre.
