Abstract: Gnathia indoinsularis n. sp. is described from Rodrigues, western Indian Ocean. The species was collected from dead coral, Porolithion clumps and encrustations, compacted coral rock and in Acropora patches intertidally and at snorkelling depths. The species is most similar to Gnathia calsi Müller, 1993, G. cooki Müller, 1989 and G. lignophila Müller, 1993 in having a bifid, inferior mediofrontal process, a rounded, superior frontolateral process, and stout and simple mandibles with a dentate blade. The species is, however, distinguished from those species by a shallow, narrow excavation of the anterior cephalon border. The species differs from the only other Gnathia species from the Mascarene Islands, G. firingae (Müller, 1991) from Réunion, in having the bifid mediofrontal process considerably posterior to the superior frontolateral process. |
