New data on the distribution and diversity of the Tonkin limestone rat (Tonkinomysdaovantieni, Rodentia, Muridae).

ABSTRACT

The paper presented novel findings of little-known species of rodents the Tonkin limestone rat Tonkinomysdaovantieni in Cao Bang Province, Vietnam with its morphological and genetic characterisation. The study summarises data on the distribution of this data-deficient species, available museum collections, genetic samples, information on its taxonomy and ecology, important to establish the proper conservation status of the species. An exhaustive map of the findings is provided. It is shown that, based on the data currently available, the species does not require taxonomic revision and also, apparently, does not need a special conservation measure; its status may be established to date as Near Threatened B1a+2a and the current population trend - Stable, IUCN.
