Hemiphractus johnsoni is sexually dimorphic; females are significantly larger than males. Snout to vent length in males averages approximately 52.9mm, while females average 77.2mm in length. There are scattered tubercles on the dorsal surface and forearms, and poorly developed tubercles on the hind limbs, of all hemiphractine species. The granular eyelids also have one or two enlarged conical tubercles. On the tip of the snout of Hemiphractus johnsoni is a small, triangular and dorsoventrally flattened, fleshy proboscis. The shape of this proboscis is one of the ways Hemiphractus johnsoni differs from the other hemiphractine species. A unique feature in Hemiphractus johnsoni is the presence of a small, round post- orbital depression with a light crossbar; conversely Hemiphractus johnsoni lack the provomerine teeth that other hemiphractine species possess. The color pattern of the dorsum is tan-brown with reddish mottling and darker spots. The forelimbs and hind limbs are a pale ground color with dark transverse. The outer digit of the unwebbed hands are noticebly darker than the inner digits. The back feet have basal webbing and the adhesive discs of the toes are slightly smaller than those of the fingers (Trueb 1974).
