Abstract :
An updated checklist of faunal biodiversity of the spiders, in two eastern states of India,
Bihar and Jharkhand is presented herewith. A total of 116 species of spiders described under 67
genera belonging to 23 families were recorded in both the states of east India. The species
biodiversity of spiders is more in Bihar state (93 species, 55 genera, 21 families) than in Jharkhand
(35 species, 27 genera, 13 families). Only 12 species overlap in distribution in both the states.
However, most of the areas in both the states (26 districts out of 38 districts in Bihar and 15 districts
out of 24 districts in Jharkhand) are still virgin regarding the faunal survey programmes and need
intensive and extensive survey programmes in those areas by keen workers.
