Molecular data from the holotype of the enigmatic Bornean Black Shrew, Medway, 1965 (Soricidae, Crocidurinae), place it in the genus .

Although Borneo has received more attention from biologists than most other islands in the Malay Archipelago, many questions regarding the systematic relationships of Bornean mammals remain. Using next-generation sequencing technology, we obtained mitochondrial DNA sequences from the holotype of , the only known specimen of this shrew. Several shrews collected recently in Sarawak are closely aligned, both morphologically and mitochondrially, with the holotype of .
