- General aspect of the dentition : weak (teeth thinner, with less trenchant cusps)
- m2 : developed (similar to size of m1 talonid)
- M2 : present, well developed ; present, residual
- Flattening of the anterior region of the mandible : present
- m1 talonid : developed (hypoconulid, entoconid and hypoconid present)
- P3 lingual cusp : absent or extremely reduced
Body proportion
Pads
Teats
Hair ultrastructure
- Cortex of dorsal guard hair (spatula) : thick (> 1/3 medulla width)
- Cross section shape of dorsal guard hair (base of spatula) : round or slightly ovoid
- Margin of the scales located in the middle of the spatula of dorsal guard hair : crenelated
- Shape of the scales located between the base and the middle of dorsal guard hair : triangular
Coat
- Pair of wide median nuchal stripes : absent
- Coat of hindfoot : dark
- Coat of upper leg : same as ground coloration but dark posterior part
- Coat of inner upper leg : dark
- Spots on upper leg : not merged
- Coat of forefoot : dark
- Coat of upper arm : same as ground coloration but dark posterior part
- Mid-dorsal crest : absent (similar length than adjacent dorsal hairs)
- Length of hairs on tail : short (from 20 to 30 mm)
- Tip of the tail : bright
- Chin : inferior chops bordered by a large dark stripe
