stimulatrix

Learned borrowing from Latin stimulātrīx. By surface analysis, stimulator +‎ -trix.

stimulatrix

1. (rare) A female who stimulates.
   • 1803, Tiberius Cavallo, Evolution, page 81:

     I think it but reasonable to attribute them [tides] to her [the Moon's] agency, as the stimulatrix and supplier of that electric principle by which land and water, for certain lengths of space and for certain times, mutually attract and repel each other, which is the proper definition of tide.

From stimulō, stimulātum (“to urge on, goad on, stimulate”, verb) +‎ -trīx f (“-ess”, agentive suffix).
