Cophixalus tetzlaffi are small frogs, though medium-sized among Cophixalus: adult males measure 20–22 mm (0.79–0.87 in) in snout–vent length. Head is broader than long, and males have a large vocal sac. Ground colour is yellowish-grey during day, getting light grey at night. There are conspicuous blackish dorsolateral stripes, and a cream-coloured stripe running from tip of the snout to the anus.^[2]

Cophixalus tetzlaffi is only known from the Fakfak Mountains, West Papua, Indonesia.

The type locality is tropical primary forest at an elevation of 860 m (2,820 ft) above sea level. Males were found perched on herbaceous vegetation, shrubs, and leaf litter. The species can attain locally high densities.^[1][2]

As it is not known whether the species can adapt to secondary habitats, it is potentially threatened by habitat loss caused by logging and establishment of plantations.^[1]
