Spiders Biodiversity and Recording of Nesticodes rufipes from Suburban Area of South Bengaluru Karnataka

In the current study the spider’s biodiversity was surveyed, the findings of Theridiid spider Nesticodes
rufipes was recorded and documented from the suburban area of Turahalli forest, south Bangalore
Karnataka. The samples were collected, during the monsoon season as the richness of species were
encountered. Totally 11 families with 18 different species were documented and identified. Some of
the common spiders observed were signature spiders, orb web spider, garden spiny spider. Orb
weaver spider, decorative silver orb web spider, red house spider, Indian ornamental tarantula, funnel
web spider, yellow sac spider black wood spider, giant wood spider, golden lynyx spider, jumping
spider, grass crab spider, and white kneed spider. Among the 18 species, Araneidae family had
recorded highest species (05) with 27.7%, the families Nephilidae, Oxyopidae and Salticidae(02each)
had recorded with 11.11%. The other seven families had documented with (01 each) 5.55%. The
male and female spiders were found and recorded for the most dominant species. The Oxoypes
species had documented the highest number of males (15) with 37.5%. Whereas the greater number
of females had found for Argiope anasuja (25) with 18.65%. The Simpsons Diversity Index (SDI) was
0.92, indicating the high richness in the species diversity. From the study area Nesticodes rufipes was
identified and reported. The morphology of N. rufipes is very similar to that described by Saaristo
(1978) of Seychelles Finland. However, the morphometric analysis of male and female spider differed
both in size & body coloration, which might be due to geographical variations.
