We describe for the first time the sexual behavior of Pavocosa gallopavo (Mello-Leitão, 1941) (Lycosidae), analyzing encounters between 25 pairs of virgin adult individuals. Both courtship and copulation were brief, averaging 3.66 min and 1.74 min respectively. Males showed a very conspicuous and vigorous courtship, with Leg Shaking and Palpal Drumming as the most noticeable displays. Females were also active during courtship, performing Leg Waving as well as showing some level of aggression by displaying Cheliceral Opening and Pushes against males. The males mounted the females in the typical position of wolf spiders, and females initially performed intense body shakes (Bucking). The copulatory pattern consisted of alternating single insertions of both palps, with a unique hematodochal expansion by insertion. Females cannibalized males three times, two of them before copulation and the third after copulation. Copulation was brief with respect to other wolf spiders, and females were unusually active during copulation. The species would be suitable for further studies of multimodal communication and the sexual inhibition of female aggression.
