Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Carnivora Herpestidae

Scientific Name: Crossarchus obscurus F.G. Cuvier, 1825
Common Name(s):
English Common Cusimanse, Cusimanse, Long-nosed Cusimanse
French Mangouste brune
Taxonomic Notes: Considered conspecific with Crossarchus platycephalus by Wozencraft (1993), but here treated as a distinct species following Van Rompaey and Colyn (1992), Colyn and Van Rompaey (1994) and Colyn et al. (1995). The separation of C. obscurus from C. platycephalus has been supported by a recent exhaustive study based on craniometric and molecular analyses (Sonet et al. 2014).
