[1][3][4][5] The specific name katoptroides is Greek for "mirror-like" and refers to the similarity of this species to Pristimantis crucifer, but being found on the other side of the Andes.

The groin and posterior surfaces of the thighs are deep blue to dark brown, sometimes with orange spots on the edges.

[4] Pristimantis katoptroides occurs in montane and submontane cloud forests at elevations of 650–1,800 m (2,130–5,910 ft) above sea level.

Although considered generally rare,[1] Pristimantis katoptroides is observed with some frequency in eastern Ecuador.

[4] Cattle grazing and mining activities can be local threats,[1][4] but its presence in secondary forests suggests some degree of tolerance to human impacts.
