With the intention of providing pelvimetric values that allow the selection of animals with better characteristics for reproduction, we studied the X-ray of the pelvis, in ventro-dorsal projection of 12 adult animals, six males and six females, belonging to the National Center of Primates - CENP. The measurements were made to right diagonal diameters (RDD), left diagonal diameter (LDD), bi-iliac middle diameter (BIMD), bi-iliac upper diameter (BIUD), bi-iliac lower diameter (BILD), sacrum-pubic diameter (SPD), and the input area of the pelvis (IAP), which were compared in relation to sex and bodily correlated with the biometrics. The results of the means and standard deviations regarding pelvimetry (cm) were: for the RDD in males of 1.91?0.14 and in the females of 2.05?0.08; LDD in males of 1.85?0.16 and in females of 2.03? 0.08; BIMD in males of 1.46?0.12 and in the females of 1.5?0; BIUD showed in males 1.3?0.1 and in females of 1.3?0.06; BILD in males of 1.35?0.15 and in females of 1.25?0.08; SPD in males of 1.68?0.09 and in females of 1.93?0.13; IAP in males of 1.9?0.26 and in the females of 2.23?0.13. It was concluded that the pelvis of Callithrix jacchus could be classified as dolicopelvic type, there is sexual dimorphism in relation to the pelvis of adult animals and that the bodily measurements have low positive correlation with pelvic measurements. O sagui-de-tufo-branco se destaca como um importante primata neotropical para as pesquisas biom?dicas. Com o intuito de fornecer valores pelvim?tricos que permitam a sele??o de animais com melhores caracter?sticas para a reprodu??o, estudaram-se radiografias da pelve, em proje??o ventrodorsal, de 12 animais, sendo seis machos e seis f?meas, adultos, pertencentes ao Centro Nacional de Primatas - CENP. As mensura??es realizadas foram referentes aos di?metros diagonal direito (DDD), diagonal esquerdo (DDE), bi-il?aco m?dio (DBIM), bi-il?aco superior (DBIS), bi-il?aco inferior (DBII), sacrop?bico (DSP), al?m da ?rea de entrada da pelve (AEP), os quais foram comparados em rela??o ao sexo e correlacionados com a biometria corp?rea. Os resultados de m?dias e desvios-padr?o com rela??o ? pelvimetria (cm) foram: para o DDD nos machos de 1,91?0,14 e nas f?meas de 2,05?0,08; DDE nos machos de 1,85?0,16 e nas f?meas de 2,03?0,08; DBIM nos machos de 1,46?0,12 e nas f?meas de 1,5?0; DBIS nos machos de 1,3?0,1 e nas f?meas de 1,3?0,06; DBII nos machos de 1,35?0,15 e nas f?meas de 1,25?0,08; DSP nos machos de 1,68?0,09 e nas f?meas de 1,93?0,13; AEP nos machos de 1,9?0,26 e nas f?meas de 2,23?0,13. Concluiu-se que a pelve de Callithrix jacchus pode ser classificada como do tipo dolicop?lvica, existe dimorfismo sexual em rela??o ?s pelves de animais adultos e que as medidas corp?reas apresentam baixa correla??o positiva com as medidas p?lvicas.
