          Abstract

          We report here a set of observations on mating behavior and female accompaniment by the whiptail lizard Cnemidophorus ocellifer in an area of Caatinga (xerophilous open forests) in the state of Rio Grande do Norte, northeastern Brazil. We observed a stationary male lizard performing repeated vibratory movements of the pelvis and tail base upon the sandy soil. Since that male was in front of a burrow in which a female of the same species was sheltered, we hypothesize that this behavior may be part of a courtship display. We continued the observation and later, when the female emerged from the burrow, the male climbed on her and the copulation occurred. The incident of accompaniment observed was characterized by one male continuously accompanying a female during foraging. Plausible functional explanations for a male accompany a female include mating guarding, post-copulatory courtship, and sperm loading. By accompanying females, males would be guaranteeing insemination by multiple copulation and stimulation of the female, and protecting their paternity by chasing away other males, diminishing the chances of extra-pair copulations.

          Nós relatamos uma série de observações sobre o comportamento de acasalamento e acompanhamento da fêmea no lagarto-da-cauda-de-chicote Cnemidophorus ocellifer em uma área de Caatinga no estado do Rio Grande do Norte, Brasil. Nós observamos um macho estacionário realizando movimentos vibratórios da pélvis e base da cauda sobre o solo arenoso. Uma vez que o macho estava em frente à abertura de uma toca onde uma fêmea se encontrava abrigada, nós sugerimos que esse comportamento faz parte da exibição de corte. Continuamos a observação e posteriormente, quando a fêmea saiu da toca, o macho engajou-se em montá-la e progrediu para uma cópula. A ocasião de acompanhamento da fêmea foi caracterizada por um macho continuamente acompanhando uma fêmea durante o forrageamento. Explicações funcionais plausíveis para uma fêmea ser acompanhada por um macho incluem guarda de parceiro, corte pós-copulatória e fornecimento de estoque de esperma. Ao acompanhar as fêmeas, os machos estariam garantindo a inseminação através de múltiplas cópulas e estimulação pós-copulatória da fêmea, e protegendo a paternidade afugentando outros machos, diminuindo as chances de cópulas extra-par.
