Resumen:
We described and analyzed female sexual response in the tarantula Grammostola vachoni Schiapelli and Gerschman 1961 under three series of 10 experiments each with different situations for the encounters male-female: males free in terrarium but with no access to female; males confined into a glass cup at 30 cm of female burrow and; males confined into a glass cup over a heavy stone closing the female burrow. We observed leg palpal tapping and body movements of females in response to male courtship. Leg and palpal tapping could indicate female receptive condition and her attractiveness and also could orient males towards her location. These females responded with leg and palpal tapping only to males which present long courtships together with active searching (walking) for female’s location. Female responses are discussed in the light of sexual selection and predation risks.
