This subspecies is markedly smaller (at least in skull length) than Bassaricyon neblina neblina and Bassaricyon neblina osborni, with the fur longest and most strikingly reddish of all the Olinguito populations (reddish with golden and black tipping), and more golden brown face and and reddish brown limbs, with the limbs well-furred. Though similar in overall skull length to Bassaricyon neblina hershkovitzi, the skull is especially wide for its size (Table 8), with broad zygomata, braincase, and rostrum compared to that subspecies.

Distribution.

This subspecies is recorded from the Urrao District of Colombia (2200–2400 m in Huila and Antioquia Departments), on the western slope of the Western Andes, where it is documented by specimens collected in 1951 by Philip Hershkovitz.

Etymology.

The name refers to the rich reddish-brown pelage of this subspecies (Figures 3, 14).

Holotype.

FMNH 70722, adult male, skin, skull, and postcranial skeleton, Rio Urrao, 2400 m, Urrao, Huila Department, Colombia (collected by P. Hershkovitz, 24 April 1951).

Paratypes.

FMNH 70721, adult female, skin, skull, and postcranial skeleton, Rio Ana, 2200 m, Urrao, Huila Department, Colombia (collected by P. Hershkovitz, 19 April 1951); FMNH 70723, adult male, skin, skull, and postcranial skeleton, Guapantal, 2200 m, Urrao, Antioquia Department, Colombia (collected by P. Hershkovitz, 28 April 1951).
