Strange white Langur found in Lanka
A team of Sri Lankan researchers has discovered a strange white
Langur monkey in the rain forests of Southwestern Sri Lanka.
New colour morph
This is a new colour morph of the purple faced leaf Langur (Semnopithecus
vetulus) which is endemic to the island.
The research team included Galle Wildlife Conservation Society's
Madura A de Silva and Nadika C Hapuarachchi, and Nations Trust Bank
Primate Conservation Project's P A Rohan Krishantha. The team has
discovered over 30 monkeys of this new colour form in 14 troops. The new
colour morph was named as the Galanthus (snow white) colour morph.
Galanthus colour morph was observed among troops mainly from rain
forests and rain forest associated habitats.
"Sri Lanka has four subspecies of the purple faced leaf langur from
four different geographical zones. The new colour morph belongs to the
Southern purple faced leaf langur (Semnopithecus vetulus vetulus)," said
According to researchers, all white individuals had black naked parts
of the face and beige to ashy brown crown hair. None had red eyes and
body and limbs were white, sometimes with ashy patches. They have
identified adults, juveniles and infants of both sexes of this new
The researchers also observed that most rain forests, in which these
individuals are observed, are adjoining commercial lowland tea
plantations and tea smallholders. Therefore, the encroachment of rain
forest by tea cultivations has been a major issue related to the
Galanthus colour morph.
