曹维特长臂猿于2002年在越南被重新发现，2006年在中国被重新发现。这是唯一已知的种群，约有110只个体，位于中国-越南边境。除了它的种群数量和分布之外，人们对它知之甚少。根据2007年至2009年两年的监测资料，描述了中国地区曹维特长臂猿的社会结构和种群动态。在这个地点建立了四个研究小组，包括1个成年雄性，2个成年雌性和2-6个后代。在研究过程中，两组两只幼崽消失了。2008年11月至2009年2月，3组共出生4例婴儿。在其中两组中，两名成年女性都有独立的婴儿。这些观察表明，曹维特长臂猿生活在一夫多妻制的群体中，与通常的只有一只成年雌性的一夫一妻制群体相反，但与康科尔长臂猿和海南长臂猿的社会组织相似。我们观察到1只成年雄性和2只大型幼虫协调分散，雄性与新到达的雌性结成一对。我们的观察结果支持了人们对长臂猿社会组织中的可变性的日益增长的认识。
The Cao Vit gibbon (Nomascus nasutus) was rediscovered in 2002 in Vietnam and then in 2006 in China. This is the only known population with about 110 individuals located along the China-Vietnam border. Little is known about it other than its population size and distribution. We describe the social structure and group dynamics of the Cao Vit gibbons in China based on 2 years of monitoring from 2007 to 2009. Four established study groups at this site consisted of 1 adult male, 2 adult females and 2–6 offspring. Two juveniles in 2 groups disappeared during the research. Four infants were born in 3 groups from November 2008 to February 2009. In 2 of the groups, both adult females had dependent infants. These observations suggest that Cao Vit gibbons live in polygynous groups, contrary to the usual monogamous group with only 1 adult female, but nevertheless similar to the social organization of both N. concolor and N. hainanus. We observed a coordinated dispersal of 1 adult male and 2 large juveniles, and the male formed a pair with a newly arrived female. Our observations support a growing awareness of variability in gibbon social organization.
