A general term for animals in the genus Presbytis, which are found in Asia east of Pakistan, among the animals of the family Cercopithecidae, order Primates, class Mammalia, subfamily Colobinae. There are 14 species of monkeys in this genus, Presbytis , all of which feed mainly on leaves, have a slender build with a body length of 50-70 cm, a tail length of 50-100 cm, and are also called lanky monkeys. The color of the fur varies from species to species, but they are divided into four subgenera based on the color of the babies. Those with black babies are in the subgenus Langur, those with white cheeks and gray or black elsewhere in the subgenus Kasi, those with white bodies in the subgenus Leaf Monkey, and those with orange babies in the subgenus Luton. Of these, the two subgenera Langur and Kasi are distributed in the Indian subcontinent and Sri Lanka, and in the strict sense, these are called langurs. The Hanuman langur ( P. entellus ) of the subgenus Langur lives throughout the region, the Nilgiri langur (P. johnii) of the subgenus Kasi lives in the southern tip of the Indian peninsula, and the purple-faced langur ( P. senex ) in Sri Lanka. All three species form small monogamous groups, with territories of about one square kilometer.

哺乳(ほにゅう)綱霊長目オナガザル科コロブス亜科のうち、パキスタン以東のアジアに分布するラングール属に含まれる動物の総称。この属Presbytisのサルには14種があり、いずれも木の葉を主食として、体長50~70センチメートル、尾長50~100センチメートル、ほっそりとした体格をもち、ヤセザルともいわれる。 体毛の色は種ごとに違うが、赤ん坊の体色により4亜属に分けられる。赤ん坊が黒いものがラングール亜属、頬(ほお)が白く他が灰色または黒いものがカシ亜属、全身白いものがリーフモンキー亜属、オレンジ色のものがルトン亜属である。このうちラングール、カシの2亜属はインド亜大陸とスリランカに分布し、狭義にはこれらをラングールとよぶ。ラングール亜属のハヌマンラングールP. entellusはその全域、カシ亜属のニルギリラングールP. johniiはインド半島南端部、パープルフェーストラングールP. senexはスリランカにすむ。この3種はいずれも小型の単雄群をつくり、群れは1平方キロメートル程度の縄張り(テリトリー)をもつ。 [川中健二] [参照項目] | |©木村しゅうじ"> サルのおもな種類(オナガザル類)〔標本… 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
