COMMENTS

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.
