The genus Mallomonas (Mallomonadales, Synurophyceae) in several Southeast Asian urban water bodies -: the biogeographic implications

We report the occurrence of 10 Mallomonas taxa from several urban water bodies in four Southeast Asian cities in Malaysia, Singapore and Indonesia. Apart from some cosmopolitan or pantropic species, the two presumed Asian synurophyte endemics (Mallomonas grata and Mallomonas ocellata) were found. We discuss the patterns of their geographic distribution that could contravene Finlay's neutral model of ubiquitous dispersal of microbial eukaryotes for these two species.
