Primary type information: Primary type material: holotype worker. Primary type locality: U.S.A.: New York, Richs Spring (correctly Richfield Springs) (no collector’s name). Primary type depository: unknown (not in MSNG, presumed lost). Type notes: Smith, 1957b: 162, says the holotype could not be found in MSNG, but adds that there are “two workers in USNM which appear to belong to the original series”. However, in the original description Emery states that he has only “one worker”).
