Nationwide Financial Services has formed an  investment management business and tapped well-known mutual fund executive   Paul   Hondros to run it.     
The new company, with $19 billion of assets under management, will be  based in the Philadelphia area, where Mr. Hondros lives. 
  
As yet unnamed, it will combine Nationwide Advisory Services and Morley  Financial Services, an investment manager Nationwide bought in May. 
Mr. Hondros helped transform Fidelity Investments, Boston, into a major  mutual fund seller through banks and other intermediaries. He left Fidelity   in 1997 to become president of Pilgrim Baxter & Associates, a subsidiary of   United Asset Management, Boston. He left Pilgrim Baxter in the fall after a   deal to sell it to Nationwide fell through.       
  
Mr. Hondros' duties will include adding new funds, possibly acquiring  investment management companies and expanding distribution, the company   said. It is too early to say whether Nationwide's new unit will expand   beyond its main distribution base of insurance agents, a company spokesman   said.
