Dear colleague,

may I suggest you be more precise and scientific when talking about taxonomy?

I would be glad to assist you but which particular taxonomic group of spiders are you working on?

Respectfully,

D.Telnov

Dr. Shah,

Are you seeking information about the 'Golden Silk Spiders' of the family Nephilidae or more broadly are you wanting to find spiders in a variety of families that might have yellow silk?

Dear Sir

Thanks for your kind information.thats exactly what I mean . Systematic position of golden silking spiders.

The golden silk spiders are classified in the family Nephilidae (or sometimes as a subfamily Nephilinae in Tetragnathidae). I am not familiar with the African species but here are a few papers that might help:

These few can get you started, but I suggest that you use scholar.google.com to find more papers on the fauna you seek to study.

Dear Sir

Thanks for your kind information.

Quick update, some recent studies on the phylogeny of orb-weavers have concluded that nephilids are a subfamily of the Araneidae. I include here the link to the world spider catalog for reference.

Thanks.highly appreciated.
