international online community for dna barcoding professionals
Dear meenakshi I know one person who is a student of Dr. D. B. Bastawade. He works on the theraphosidae. you can contact him or even talk to me (although i am working on amphibians). You have not specified where you work and what kind of facilities you ahve in your lab. I can suggest you even some good places where you can send your DNA samples of interest for sequencing. They are prety cheap. So you have to make you problems a little bit more clear.
with warm regards
