Draft of the IUCN Primate Specialist Group, 2000 / Orlando Workshop, Febr. 2000

This review is not supposed to answer taxonomic questions; older subpopulation synonyms are partly maintained in the database to assure that data valid for a local subpopulation are not included as valid for the whole subspecies or species.

Distribution maps

Localities in which animals were found before 1960 or in which the date of occurrence is unknown are generally marked by a symbol with white center; similar black symbols indicate occurrence or publication from 1960 on (in some cases, publication may be much later than occurrence). Trade origin, if known (animals, possibly from elsewhere, offered for sale) is indicated by a symbol in parentheses. If for a region only old localities are noted, this may either be due to vanishing of animals from the regions or due to lack of published survey data. Abundant actual evidence in a region does not necessarily mean that animals are abundant, but may also indicate exploitation or habitat destruction leading to increased discovery of animals.

Specimen lists compiled as a supplement to the distribution maps

The following data are included:

Column 1: place number. Locations in close proximity may be listed under one number. On the distribution map, the number of the place is noted next to the symbol indicating the place of origin; in the type localities, the underlined name of the location is noted instead of a number.

Column 2: names of localities (place of observation/capture or origin of museum specimens as noted on labels), including coordinates, when given. Places may in some cases be trade origin, for instance local markets to which the animals had been brought; if this is known, this is noted both in the lists and on the maps.

Column 3: The altitude of habitat / place of origin in meters.

Column 4: date of observation, capture or importation. If authors provide no date but indicate the present-day occurrence of lorises, the date of publication is mentioned in parentheses. If the time of occurrence is not mentioned, "prior to (date of publication)" is noted (in some cases, publication may be much later than occurrence). If it appears that the information was published much later, no date is mentioned. More recent dates (from 1960 onwards) are printed bold and underlined.

Additional information, if available: abundance, other; noted below the location data in a separate line.
