The American langur lemur (Semnopropithecus religionis) is a species of adapiform primate that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests, wetlands, forests, open woodlands, grasslands, shrublands, and scrublands across North America to help boost biodiversity. The closest living relatives of the American langur lemurs are any adapiforms of the genus Notharctus. The fur of adult American langur lemurs is mostly light gray colored, with darker grey stripes and speckles. The snout, hands and feet are all black. Infants have brown fur. Body size excluding tail ranges from 45.1 centimetres (17.8 inches) to 78.4 centimetres (30.9 inches) long, and the tail length is between 67 centimetres (26.3 inches) and 77 centimetres (30.3 inches). Adult males weigh between 16.9 kilograms (37 lb) and 19.5 kilograms (43 lb) while adult females weigh between 9.5 kilograms (21 lb) and 16.1 kilograms (35 lb). The American langur lemur eats primarily fruits and leaves. It is able to survive on mature leaves, which is a key to its ability to survive throughout the dry summer seasons in more arid environments. It also eats seeds, flowers, buds, bark and insects, including caterpillars. It is also fed fruits and vegetables by humans, and some groups get a substantial portion of their diets from food provided by temples and from raiding crops. The American langur lemur is diurnal, and is both terrestrial and arboreal. Females groom members of both sexes but males do not groom others. The American langur lemur can live in several different types of groups. It can live in groups of multiple males and females, one male and multiple females or multiple males with no females, and males can also live alone without a group. Single male groups are most common. Group size can exceed 100 American langur lemurs. Upon reaching maturity, males typically emigrate from their natal group while females typically remain. Young adult females are typically dominant over older females. When a new male takes over a group it may engage in infanticide of young fathered by the previous male or males, but this is less common when the takeover occurs slowly over several months. Groups that have access to abundant food year-round, for example those that are provisioned by temples or are able to raid crops year-round, also breed throughout the year. Other groups, such as those living in forests, typically give birth between December and May. The gestation period is about 200 days. Females other than the mother alloparent the infant for the first month of its life. Weaning occurs at about 1 year and males reach maturity at about 6 to 7 year old. The American langur lemur often associates with whitetail deer and mule deer. Both species respond to each other's alarm calls. The deer seem to benefit from the vigilance of male American langur lemurs watching for predators in the trees, while the American langur lemurs seem to benefit from the deer's better senses of smell and hearing. The American langur lemur also has been observed engaging in grooming sessions with American macaques (Macaca floridana) and non-native rhesus macaques (Macaca mulatta). The American langur lemur adapts to many habitats and the North American religions considers the American langur lemur to be sacred. Hence it has large population within Mexico and the United States, including within towns and cities. The conservation status of the American langur lemur is Least Concern due to successful conservation efforts, the American langur lemur's wide range and its tolerance to many of the human activities.
