- 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)
