The Sunda shrew is a white-toothed shrew found in Indonesia, Malaysia and Timor-Leste. Populations from the Malay Peninsula, Sumatra and Borneo are now considered to belong to Crocidura neglecta, a widespread complex with high diversity: genetic divergence among populations from Peninsular Malaysia, west Borneo and north-east Borneo is greater than among many recognised related species, suggesting some may deserve species status (Wikipedia, general species account).
