Four Republican state senators were falsely identified as leaders of Senate committees in documents sent to the state comptroller by Senate payroll staff in March, authorizing tens of thousands of dollars in stipends earmarked for other lawmakers.

The arrangement was identical to one that benefited three of their Democratic allies in the chamber, and was heavily criticized after The New York Times disclosed it this week.

Documents obtained through a Freedom of Information request show that Senator Thomas F. O’Mara of the Finger Lakes region and Senator Patrick M. Gallivan of the Buffalo area were listed as chairmen of the transportation and education committees in two emails sent to the comptroller in March. The men do not hold those positions, though they are vice chairmen of the committees.

The emails, labeled “Senate Certifications,” requested total pretax payments of $15,000 for Mr. O’Mara and $18,000 for Mr. Gallivan. Stipends for such positions were paid in March and early April, according to the comptroller’s office.
