UPDATE 1-Bolivia's Morales calls for talks on autonomy

(Adds recall votes)

By Carlos Alberto Quiroga

LA PAZ, May 8 (Reuters) - Bolivian President Evo Morales called on Thursday for urgent talks with regional leaders to ease divisions over mounting demands for autonomy, but some said they were not yet ready for negotiations.

Bolivia's richest region, Santa Cruz, voted heavily in favor of autonomy from the central government in a referendum on Sunday and the leaders of at least three other regions said they would not meet with Morales until they held similar votes over the next two months.

The eastern lowland regions of Tarija, Beni and Pando plan referendums before the end of June.

The votes could strengthen the autonomy movement and increase conflict with the western highlands where Morales, a leftist and Bolivia's first indigenous president, has his support base.

"This Bolivian family cannot be divided," Morales said in Santa Cruz just days after his supporters clashed with autonomy backers in the referendum. "Autonomy must be for all Bolivians, with social justice, not autonomy just for groups."

Morales, who has said the autonomy votes are illegal, asked for all of Bolivia's nine regional governors to meet with him on Monday to avoid further division.

Meanwhile, in a surprise session, the Senate on Thursday passed a controversial law calling for a series of recall elections that could either ratify the mandates of Morales and the governors or possibly vote them out of office.
