Abstract
Scurrula neoraindica L.J. Singh,, V. Ranjan, Anant Kumar & G. Krishna (Loranthaceae) is described and illustrated from Neora Valley National Park of West Bengal, India as a new species along with an inventory of host species and conservation status. The new species closely resembles S. parasitica L. and S. paramjitii L.J. Singh of the sub-tribe Scurrulinae of Loranthaceae. However, the new species is distinct in morphology of vegetative and reproductive characters from all previously known species. A detailed description, photographs, distribution, illustrations, comparative table of key characters and an identification key to Scurrula species of India are provided.
