As it is most widely recognised today, Cebidae includes six genera organised into three subfamilies, though one of these genera is currently purely formal in that it contains only a single species.

Such knowledge on the temporal order of ancestral branchings separating these ceboid genera from one another is needed not only to solve problems of higher-level ceboid systematics but also to be able to place the problems of lower-level ceboid systematics in their broader phylogenetic context.
We plan to gather extensive additional DNA sequence data in order to test the congruent branching arrangements of the epsilon and IRBP maximum parsimony trees, especially those arrangements that are controversial when compared to the cladistic evidence from previous morphological studies (11-14).
The Cebidae belong to the superfamily Ceboidea, suborder Anthropoidea.
Marmosets are the smallest of all monkeys and are more primitive than the Cebidae.
Their fingers end in claws instead of nails; their scent-marking behavior is like that of the LEMUR, as is the lack of a strong bond between the female and her young.
Social group size varies from that of the squirrel monkey, which lives in troops of up to 500 individuals, to that of the owl monkey, which lives in small nuclear family groups.
Many of the Cebidae and Atelidae have strong prehensile tails that are largely hairless on the underside and have sensitive tactile pads.
The Cebidae and Atelidae are generally very enterprising when it comes to obtaining food.
Mites collected from the auditory canal of Cebus apella (capuchin monkey), familyCebidae, were identified as Fonsecalges johnjadini (Psoroptidae, Cebalginae).
This group of Cebidae is arboricolous and can live in any kind of neotropical rainforest (Freese & Oppenheimer 1981).
In this study, the mites were collected from both right and left auricula and many mites were removed from the earwax characterizing these sites, indicating that they were a favorite habitat for these mites in this species of primate.

They range in weight from only 2.5 to 19.5 ounces, but their thick fur deceptively makes them look larger and heavier.
The smaller marmosets venture into the very top of forest canopies to hunt the insects that are abundant there.
any of the Cebidae species have strong prehensile tails that are largely hairless on the underside and have sensitive tactile pads.
Growth of Functional Cranial Components in Saimiri sciureus boliviensis (Cebidae): A Longitudinal Study(Site not responding. Last check: 2007-10-26)
ABSTRACT:Ten male Saimiri sciureus boliviensis (Cebidae) born at the Centro Argentino de Primates (CAPRIM) were divided into a control group (five animals fed ad libitum on a 20% protein diet) and an undernourished group (five animals fed ad libitum on a 5% protein diet) at weaning (seven months old).
Each animal was radiographed monthly from both later-lateral and dorsal-ventral views, from the first to the third year of age.

Epsilon-globin and beta-2-microglobulin (both autosomal) infer a sister-relationship between the Atelidae and Pitheciidae; IRBP (autosomal) supports a clade of Pitheciidae and Cebidae; G6PD (X-chromosomal) groups the Atelidae with the Cebidae.
Such disagreement among molecular datasets is consistent with the hypothesis that an evolutionarily short internode separates the two divergence events giving rise to the progenitors of the platyrrhine families; the conflicting nuclear topologies would then be the result of differential lineage sorting at various genetic loci.
Cebus apella (Primata: Cebidae) as a New Host for Fonsecalges johnjadini (Acari: Psoroptidae, Cebalginae) with a Description of Anatomopathological Aspects
This group of Cebidae is arboricolous and can live in any kind of neotropical rainforest (Freese and Oppenheimer 1981).
Each group of these monkeys consists of 8 to 18 members (Kuhlhorn 1939 apud Freese and Oppenheimer 1981).
