The genus Phycopeltis (Trentepohliales, Chlorophyta) from tropical Southeast Asia
Twelve species of the aerophytic green alga Phycopeltis from epiphyllous biotopes in Peninsular Malaysia, Sumatra and Java are reported. Phycopeltis theaensis sp. nov. is described as a new species from leaves of Thea sinensis at mountainous tea estates in Peninsular Malaysia. Two of the species found during the investigation (P.arundinacea P.epiphyton) seem to have a cosmopolitan distribution in tropical, subtropical and temperate ecosystems. Seven species (P. amboinensis, P. aurea, P.irregularis, P.pseudotreubii, P.treubii, P.treubioides, P.vaga) appear to have a pantropic distribution. Phycopeltis kosteriana, P.prostrata and P.theaensis have yet to be reported outside the Indo-Malayan-North Australian phycogeographical region.
