Abstract

Field observations of larger mammals in Laos, 1994-1995.

Abstract

Mammal records are presented from surveys in eleven extensive forest areas in Laos. Most surveyed areas were south of 18°40'N but one site was in the far north of the country. Particularly significant information was gathered on two newly described ungulates, Saola, Pseudoryx nghetinhensis and Large-antlered Muntjac, Megamuntiacus vuquangensis and another unidentified species of muntjac probably referable to Muntiacus truongsonensis. A (sub)species of Francois's Langur endemic to Laos, Semnopithecus (francoisi) laotum was recorded for the first time in at least 25 years, at five locations. Globally Threatened species (sensu IUCN 1996) recorded were : Pygmy Loris Nycticebus pygmaeus (provisionally identified), Pig-tailed Macaca nemestrina, Assamese M. assamensis and Bear Macaques M. arctoides, Douc Langur Pygathrix nemaeus, Dhole Cuon alpinus, Asiatic Black Bear Ursus thibetanus, Back-striped Weasel Mustela strigidorsa, Clouded Leopard Pardofelis nebulosa, Tiger Panthera tigris, Asian Elephant Elephas maximus, Gaur Bos gaurus, Southern Serow Naemarhedus sumatraensis, Saola and Inornate Squirrel Callosciurus inornatus. Data Deficient species are also listed. A record of Spotted Linsang Prianodon pardicolor was one of few anywhere in recent years. A major structured programme of collecting is required to clarify the complex taxonomy of the squirrel genera Tamiops and Callosciurus in Laos.
