Rattus blangorum


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Rattus blangorum
Species Authority: Miller, 1942
Common Name/s:
English Aceh Rat
Taxonomic Notes: Still represented only by the holotype and another specimen. Originally described as a species (Miller, 1942), but later included in R. tiomanicus (Musser and Califia 1982, Corbet and Hill 1992, Musser and Carleton 1993). Recent multivariate analyses employing morphometric traits of Sundaic samples of the R. tiomanicus complex indicate blangorum to be distinct from all other insular samples in that assemblage (Musser and Carleton 2005). The taxonomic validity of this species is in question (D. Lunde and K. Aplin pers. comm.).
