摘要

The present assessment of Rotifera biodiversity of the eastern Himalayas reveals a total of 172 species belongingto 39 genera and 19 families from Arunachal Pradesh, the northeastern-most state of India. The richness forms ~59% and~40% of the rotifer species known till date from northeast India (NEI) and India, respectively. Three species are new to theIndian sub-region, four species are new to NEI and 89 species are new to Arunachal Pradesh; 27 species indicate globaldistribution importance and 25 species reported exclusively from NEI merit regional interest. The rich and diverse alpha diversityand biogeographic interest of Rotifera of this Himalayan biodiversity hot-spot is noteworthy in light of predominanceof the small lentic ecosystems. Lecanidae Brachionidae Lepadellidae Trichocercidae collectively comprise ~71% oftotal rotifer species. Brachionidae records the highest richness known from any state of India. This study indicates the role ofthermophiles with overall importance of ‘tropic-centered’ genera Lecane and Brachionus, and particularly at lower altitudes;species of ‘temperate-centered’ genera Keratella, Notholca and Synchaeta are notable in our collections at middle and higheraltitudes, while Trichocerca and Lepadella are other species-rich genera. The rotifer fauna shows a mixture of ‘tropical’ and‘cold-water’ elements, depicts the littoral-periphytonic character, and records a large component of cosmopolitan species.The study of more collections from middle and higher altitudes of Arunachal Pradesh are desired for an update on Rotiferafrom the eastern Himalayas.
