Abstract
A new freshwater bryozoan species, Plumatella mukaii, is recognized from eastern Asia and western South America. Colonies and statoblasts both bear a resemblance to P. emarginata, and have often been confused with that species, especially in Japanese studies. Floatoblasts and sessoblasts are enclosed within a tough, wrinkled, membrane which resists removal by mechanical means. Floatoblasts are generally smaller than those of P. emarginata, but display unusually high variability in their overall dimensions. The species has been reported from both lentic and lotic habitats. In Asia, the range includes Japan, Korea, China, India and Indonesia. It has most recently also been found at several sites in Chile. The recognition of P. mukaii narrows the previously reported range of P. emarginata and invites a re-inspection of that species worldwide.
