Popis: | A 2012 microphytobenthos survey from coral reef environment at Napuka Atoll (Tuamotu Archipelago, South Pacific) focussed on diatom assemblages. Atolls are tropical carbonate, productive ecosystems, with a fast turnover, from which benthic diatom floras are poorly known. When compared to younger volcanic islands from the same area, Napuka shows a poor colonisation by benthic diatoms. Although normally rare, Achnanthales occur in the assemblages from Napuka. In the tidal zone, marine debris of sponge origin were colonized by several taxa, among others a small-celled Cocconeis here described as C. napukensis sp. nov. The new taxon has some likeness to Cocconeis subtilissima Meister and to C. vairaensis Ricard. Original drawings and type material are examined when available. A lectotypification and an emended description of Cocconeis subtilissima are proposed, along with the description of Cocconeis suzukii sp. nov. and Cocconeis meisteri sp. nov. from Meister type material. The morphological features of C. napukensis are investigated with scanning electron miscroscope (SEM) and light microscope (LM). Until now C. napukensis has not been found in the other investigated sites of Tuamotu and Society Archipelagos. |
